Help! My Child Doesn’t Want to Wear Glasses!

Do your kids need glasses in order to see clearly? Maybe they have a strong case of nearsightedness, perhaps they have astigmatism, or another type of refractive error. Whatever the cause, getting your kids to wear eyeglasses can be a parenting challenge.

Dr. Muldoon treats patients from all over Uptown Houston, Texas with their vision correction needs. The knowledgeable, caring staff at Briargrove Eye Center can help you and your kids if they’re struggling with their glasses or don’t want to wear them.

Why Won’t My Child Wear His or Her Glasses?

To help your children get the best vision possible, you first need to understand why they’re fighting with you over their glasses. It usually stems from something physical, emotional, or social, such as:

  • Wrong fit
  • Wrong prescription
  • Personal style
  • Reactions from friends

How do you know which it is? Pay close attention to the signs, from what your kids say, to how they behave, to how they interact with others.

Physical

Improper fit is a big reason why glasses could feel uncomfortable. If they slip down, itch behind the ears, or put pressure on the bridge of the nose, it can explain why a child wouldn’t like to wear them.

If there’s been a big change to their prescription, they may need time to get used to it. If they were given the wrong prescription, they may be straining their eyes, getting headaches, or having eye fatigue. An incorrect prescription can make wearing glasses painful or awkward. It doesn’t correct their vision, either, so they’ll still see blurry images. When this happens, your eye doctor can check the prescription and make an adjustment.

Emotional

Your kids at home aren’t the same as your kids in school, on the sports field, or with their friends. They may be afraid of being made fun of in school, or they may not want the sudden attention on their appearance. These feelings can be even stronger among the tween and teen set.

Social

Even young kids can feel different when they put on a pair of glasses, especially if it’s for the first time. Feeling different or weird, in their eyes, translates to a negative experience. When wearing glasses makes them feel like the odd man out, they may not want to wear them. The last thing your child wants is to feel like a social outcast. After all, everyone wants to belong.

How We Can Help

First, bring your child in to the eye doctor for an eye exam. Our optometrist, Dr. Muldoon, will check to make sure that your child has the right prescription and that any vision problems are being corrected. Next, we’ll take a look at the glasses and place them on your child’s face to determine if they’ve got the proper fit. Our optician will take care of any adjustments that need to be made.

The Vision They Need, The Style They Want

Fashion isn’t only for adults. Your budding fashionista or trendy young stud wants to look awesome, so don’t forget about style. When your kids look great, they’ll feel great! Give them the top-quality eyewear they need without compromising on style. Your kids are a lot more likely to wear glasses when they like the way they look.

What You Can Do to Help

Encourage, stay positive, and don’t give up. Avoid telling them what you want them to wear. Let them choose for themselves. In the end, they’re the ones wearing the glasses. Making decisions is an important life skill, something they’ll need as they grow up and become more independent.

For younger children, use positive words to encourage them. Talk about how glasses are like magic, letting them see beautiful things around them. Show them how a pretty flower or a bright red truck looks with the glasses on, and how different it looks with the glasses off. For older kids, throw in a little pop culture. Tell them how trendy they’ll look by showing them pictures of celebrities who also wear glasses. You’ll also rack up some cool parent points.

At Briargrove Eye Center, we have the experience and unique approach to children’s eyewear that will make your kids want to wear their glasses. Schedule an eye exam today – you can book an appointment online right here. If you have any questions or concerns, give us a call and we’ll be glad to help.

Do I have Eye Allergies?

Know the symptoms of seasonal eye allergies and how to get rid of this pesky problem

As the weather warms, flower buds are opening, and your neighbors are dragging their lawnmowers out for an annual spring tune-up. And suddenly you find a need to rub your itchy, red, and sore eyes constantly. Yep, it’s that time of year again – the time that seasonal allergies blossom with the trees.

Nasal symptoms of seasonal allergies, like a runny nose and sneezing, usually get all the attention, but actually, eye allergies (your eye doctor may call it “allergic conjunctivitis”) are pretty common – affecting millions of people in the US. Grass allergy and pollen in the eyes are the primary cause of eye irritation. What’s the best treatment? And how can you get rid of your eye allergies?

Eye exam to diagnose eye allergies in Uptown Houston, Texas eye doctor’s tips on how to recognize and relieve allergies.

The ocular symptoms of your seasonal allergies are caused when your body’s immune system becomes sensitized and overreacts to an environmental trigger that’s really harmless. That trigger, called an allergen, makes contact with antibodies in your eyes – and these cells respond by releasing histamine. Histamine and other natural chemicals cause tiny blood vessels in your eyes to leak, which can lead to redness, itchiness, burning, inflammation, and watery eyes. The symptoms can range from mild to severe enough to interfere with your clear vision. Rest assured – eye allergies are not dangerous, as annoying as they can be.

However, these symptoms alone are not enough to blame seasonal allergies. All of these signs are not unique to eye allergies and could point to several different eye diseases. That’s why a precise diagnosis is imperative! Our Uptown Houston, Texas eye doctor will perform a comprehensive evaluation of your eyes to identify the cause of the irritation.

Many eye diseases can be quickly and easily diagnosed during a comprehensive eye exam. If you were diagnosed with an eye disease, such as Cataracts, Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery – now or in the future? Our Uptown Houston eye doctor has prepared the following answers to your questions about eye disease.

Avoid your trigger to get rid of eye allergies

Grass allergy and pollen in your eyes are the most typical triggers for seasonal eye allergies, often called hay fever. Since that’s the case, you’re probably wondering how you can possibly avoid these widespread allergens. Before you lock yourself in your room and wait for the seasons to change, our eye doctor recommends:

  • Keep windows closed when the pollen count is high. Use a/c in your home, office, and the car in order to clean the air around you.
  • Do not rub your eyes! This spreads the pollen (and irritation!) all over.
  • When you are outdoors, always wear glasses and sunglasses to keep pollen out of your eyes. Don’t wear your contacts! Contact lenses can exacerbate eye allergies because they are a great surface for pollen to cling to and pile up.
  • When you return indoors after being exposed to seasonal allergens, rinse your eyes with saline drops.
  • Clean your floors with a damp rag, instead of sweeping with a dry broom that pushes any pollen that’s settled back into the air.

What’s the best treatment for eye allergies?

Some of the symptoms can be managed with nonprescription drugs, especially if your eye allergies are mild. Try using artificial tears to keep your ocular surface clean. Decongestant eye drops may also help, however, it’s not a good idea to use these for more than a few days since they can worsen your condition with prolonged use.

What about antihistamines for red eyes and seasonal allergies? Antihistamine eye drops, mast cell stabilizer eye drops, corticosteroid eye drops, and NSAID eye drops are accepted short-term treatment for eye allergies. Because these are all prescription drugs, you will need to visit your eye doctor (and possibly an allergist too) to determine which medication is most suitable for you. Some non-sedating oral histamines may also be effective at relieving your symptoms, but they can dry out eyes – thereby making the irritation worse. If your seasonal allergies are extreme and get in the way of functional living, immunotherapy allergy shots or tablets may offer long-term relief.

6 Common Eye Myths Debunked

Toric Contact Lenses for Astigmatism

Astigmatism is a condition that is caused by an irregular shape of the cornea - the clear part of the eye that covers the iris and the pupil.  The cornea is usually smooth, round, and spherical but in an astigmatic eye, the cornea turns into a shape that is not spherical and develops a second curve.  One of the primary duties of the cornea is to focus light onto the retina which enables you to see clearly.  When the cornea is out of shape and develops two curves, this creates two focal points therefore causing blurred vision.

The irregular shape of the eye makes it hard for traditional contact lenses to fit and provide clear vision and therefore requires specialized contact lenses such as toric lenses or rigid gas permeable lenses (RGPs).

What are Toric Contact Lenses?

Toric contact lenses are designed to correct astigmatism and custom made to fit the eye of the patient. Rather than having a perfectly spherical surface like standard contact lenses, toric lenses have a more oblong shape made to accommodate the shape of the astigmatic eye.  Toric lenses can be made of either soft or rigid gas permeable (RGP or GP) lens material, however the soft toric lenses are more common.

Toric contact lenses are also designed in such a way that the lenses stay in place on the eye to maintain proper vision. Sometimes as the eye moves or blinks the lens can rotate considerably on the eye.  If this rotation continues with a soft toric lens, a rigid gas permeable lens might be more effective.  Rigid gas permeable lenses have a longer initial adjustment time, but once this has passed they are usually just as comfortable as soft contact lenses and they are often easier to care for.

Toric lenses are available in every wearing schedule from daily disposable to long-term wear.  In some cases you may even find colored toric contact lenses.  Due to the customization required, toric lenses tend to be more expensive and may take more laboratory time to make than traditional lenses.

If you have astigmatism, finding the right fit for your contact lenses is essential.  Speak to your eye doctor today for a full assessment to determine which type of toric lenses will work best for you to help you see and feel your best.

Contact Lenses for the “Hard-to-Fit” Patient

It is not uncommon for patients to have difficulty wearing contact lenses for a number of reasons. Due to the individual eye shape, certain conditions or impairments or the aftermath of surgery, some patients are considered to be “hard to fit” as contact lens wearers.

For hard to fit patients that prefer to wear contact lenses however, there are options available that can provide comfortable and effective contact lens wear. This will require a specialized fitting with an eye doctor that is an expert that knows your condition and the various products available to find the right match for your specific condition.  You may be considered a hard to fit contact lens candidate if you have one of the following conditions:

  • Dry Eyes
  • Astigmatism
  • Giant Papillary Conjunctivitis (GPC)
  • Keratoconus
  • Pellucid Marginal Degeneration
  • Post-LASIK or other refractive surgery
  • Presbyopia (reduced near vision common in individuals aged 40 and over).
  • Corneal Scarring

Dry Eyes and Contact Lenses

Dry Eye Syndrome causes your eyes to feel dry, gritty, burning, red, and irritated.  Dry Eye Syndrome can also cause blurred vision. Often these symptoms can sometimes worsen by the use of contacts. In fact, many people who do not normally suffer from chronic dry eyes, will experience some of these symptoms as a result of contact lens wear.

First of all, if you have chronic dry eyes, you should see your eye doctor for treatment and relief before you think about contact lenses. Once your dry eyes are treated, it is safe to try contacts and there are a number of options that can be considered.

Many brands of soft contacts and products such as disinfectant and cleansing solutions are made with ingredients that are designed to be more comfortable for individuals with dry eyes. Your eye doctor will be able to recommend some of these brands and products to you. Alternatively, gas permeable (GP) or rigid gas permeable (RGP) lenses are made with a hard material that in some cases does not dry out like soft lenses and they are able to hold a certain amount of moisture beneath the lens to keep the eye from drying out. Gas permeable lenses are a very good option and can be quite comfortable for individuals with dry eyes.

Additionally, your doctor might recommend a specific wearing schedule such as limiting the time you wear your contacts throughout the day or replacing your contacts on a more frequent basis.

Toric Lenses for Astigmatism

Astigmatism is a condition that causes blurred vision (in some cases double vision) because rather than being round, the front of the eye (the cornea) has two curves instead of one, therefore, having two focal points instead of one. This makes it hard for traditional contact lenses to fit and therefore requires specialized contact lenses such as toric lenses or rigid gas permeable lenses (RGPs).

Toric contact lenses are designed to correct astigmatism and custom made to fit the eye of the patient. Most are made of soft material designed to stay in place on the eye, however in some cases, when the rotation of the lens (due to blinking and eye movement) can’t be stopped, gas permeable lenses might be tried. Due to the customization and more complicated fitting process required for these lenses, they are more expensive and take more time for the contact lens laboratory to make than traditional lenses.

Giant Papillary Conjunctivitis (GPC) and Contact Lenses

GPC is a type of conjunctivitis in which the inner surface of the eyelid becomes swollen.  The condition can be caused or worsened by a buildup of protein deposits on contact lenses.  Your eye doctor may either recommend daily disposable lenses or RGP lenses (which are not water based) and therefore have less of a tendency for protein buildup.  Your doctor may also prescribe medicated eye drops and require you to stop the use of contact lenses until the symptoms improve.

Rigid Gas Permeable (RGP) or Gas Permeable (GP) Lenses

Rigid Gas Permeable (RGP) also known as Gas Permeable (GP) lenses are effective for many hard to fit patients.  The hard, oxygen permeable material lets the eye breathe and significantly reduces the chance of infection due to protein deposits which tend to harbor bacteria on soft lenses.  RGPs also hold moisture under the lens to keep eyes from drying out.

Rigid Gas Permeable (RGP) Lenses for Keratoconus

Keratoconus is a condition in which the cornea thins and bulges forward into a cone shape.  Traditional contact lenses may cause some discomfort in these patients and the vision may still be blurry therefore RGPs are often used for treatment for mild, moderate, and some severe cases.  Rigid gas permeable lenses may help to slow down the cone shape from worsening in some cases. Further, RGPs are able to assist in vision correction for keratoconus which is often not possible with soft contacts or even eyeglasses.

Post-LASIK or Vision Correction (Refractive) Surgery

While LASIK surgery has a very high success rate, there are vision complications and symptoms that sometimes remain.  Night vision after LASIK, in particular, can sometimes give you side effects such as glare or halos around lights.  RGPs are often effective in helping with these side effects and restoring clear vision.

Bifocal and Multifocal Contact Lenses for Presbyopia

Presbyopia is a common condition in those people usually over 40 years old in which the eyes’ ability to focus on close objects is impaired. Many people keep a pair of bifocal or multifocal glasses on hand for times when they have to read menus, newspapers, books, and other objects that require near vision.  For those that prefer contact lenses over eyeglasses, bifocal and multifocal contact lenses are an option.

For some patients that have presbyopia and need correction for distance vision as well, one option is monovision.  Monovision is a contact lens fitting process in which you wear a contact lens in one eye for distance vision and the other contact lens of your other eye for near vision.  Another option is multifocal contact lenses.  In this contact lens fitting process, both eyes are usually fit for distance vision and both eyes are used for near at the same time.  Both contact lens fitting options usually take about one week for the brain and the eyes to adjust.

If you have one of these conditions or find contact lens wear difficult for another reason, speak with your eye doctor. As technology improves there are more and more options for hard to fit contact lens patients to benefit from the comfort and convenience of contact lens use.

Gas Permeable (GP) Contact Lenses

Gas Permeable (GP) or Rigid Gas Permeable (RGP) contact lenses are an alternative to soft contact lenses that are made from a hard, oxygen permeable material.  GP lenses are currently less popular than soft lenses but offer a number of advantages and are continuing to improve as research and technology advance.

GP contacts are made of a firm plastic material which allows the passage of oxygen through the lens to your cornea and the front surface of your eye - essentially allowing your eye to “breathe”. This increases comfort, health and safety during contact lens wear.

Benefits of GP or RGP Contact Lenses

Because of the strong material and the ability to diffuse oxygen, GP lenses offer a number of advantages over soft contact lenses.

Health and Hygiene Benefits:

Unlike soft lenses, GPs don’t contain water which makes them less likely to attract and breed bacteria that can cause eye infections. Further protein deposits won’t build up on the lens, keeping them cleaner and healthier.

Because they are made with a strong durable material, GP lenses won’t tear and are easy to clean and disinfect.  RGPs maintain their firm shape and will not dehydrate.  Further GPs last longer than soft lenses - when cared for properly, a pair can last a year or more.

Comfort

GP contact lenses are custom made for each patient based on the eye’s individual curvature, size, corneal shape. Their ability to transmit oxygen reduces eye problems such as dry eyes caused by reduced oxygen that are common in many brands of soft lenses or hard (non-GP) lenses.

GP lenses have a smaller diameter than soft contacts, meaning that they cover less of the surface of your eye. While this may take some time getting used to initially, ultimately many find that they are just as if not more comfortable than soft contacts.

Better Vision

Due to the rigid material, GPs have a smooth surface and maintain their shape, moving along with the eye to hold their place.  This provides sharp and stable vision. Further they do not dehydrate, which is often a cause for reduced vision with other lenses.

Cost

Because they last so long, GPs are much more cost effective than soft lenses, especially disposable lenses that require a constant supply. Because they are made to order, there is an initial cost investment and they will take up to a week to manufacture if you do need a replacement pair.

GPs for Astigmatism

GP lenses are ideal for individuals with astigmatism that may have been told that they cannot wear soft contacts. Because of the rigid nature of the lens, they hold their shape on the eye allowing for more clear and stable vision correction.

Adapting to GP lenses

One of the downsides of GP contact lenses is that they require an adaptation period, particularly if you are used to soft lenses with a larger diameter.  One of the major differences is an experience of “lens awareness” in which you feel the edge of the lens when you blink. It could take up to a few weeks to get used to the lenses but many people report that after this initial period they find that GP lenses are just as if not more comfortable than soft lens varieties.

GP Lenses for Myopia Control and Ortho-K

Research shows that gas permeable lenses might be effective in slowing the progression or worsening of myopia or nearsightedness, particularly in children. They are also used in Orthokeratology (ortho-k), a vision correcting procedure in which you wear the lenses at night to reshape your cornea for improved vision during the day.

Bifocal and Multifocal Contact Lenses

If you are over 40 and have difficulty seeing close up, you probably have a common age-related condition called presbyopia which is when the eye’s natural lens loses the ability to focus on close objects. Presbyopia is a natural process as the eye ages and affects the majority of people from age 40 and upward.  Individuals with presbyopia are often familiar with the need to hold reading materials such as newspapers an arm’s length away from their eyes in order to see clearly, yet reading glasses with bifocal or multifocal (progressive) lenses can help.

Fortunately for those who don’t like the look, feel or inconvenience of reading glasses, there is another option. Bifocal and multifocal lenses are also available in contact lenses in both soft and Rigid Gas Permeable (RGP) varieties.

Multifocal contact lenses give you added freedom over glasses and they allow you to be able to view any direction - up, down and to the sides - with similar vision. People wearing progressive lenses in glasses on the other hand have to look over their glasses if they want to view upwards or into the distance.

The Difference Between Bifocal and Multifocal Lenses

Just as the name indicates, bifocal lenses are divided into two distinct segments for different vision powers, the first for distance vision and the second for near vision.  This enables you to clearly switch your focus from near to far as needed, but your vision will not necessarily be clear in between. The term multifocal lenses can refer to any lenses with multiple powers including bifocals, trifocals or progressive lenses. Non-bifocal multifocal lenses have a range of powers that enable you to constantly adjust your focus to see clearly from up close to far and in between.

Multifocal contact lenses are generally designed in one of two ways, as either simultaneous vision lenses or alternating vision lenses.

Simultaneous vision lenses

The most popular version of multifocal contact lenses, simultaneous vision lenses present the distance and near vision zones of the lens at the same time.  Typically after a short adjustment period your eyes learn to utilize the segment of the lens that they need to focus on the desired object and essentially ignore the other.

They come in two designs:

  • Concentric ring design: In the most basic form these are bifocal lenses that are comprised of a central circular area of one power with a ring around of the alternate power, similar to a bulls-eye.  In this design the power of the rings (either near or distance vision is interchangeable).  For intermediate viewing (18-24 inches away) extra rings can be added to create a trifocal or multifocal lens.  The width of each ring is variable depending on the power that is needed most and the edges of the rings can be blended for a smooth transition of focus, similar to progressive eyeglass lenses.
  • Aspheric design: These multifocal lenses attempt to provide a natural vision experience by blending many lens powers across the surface and center of the lens. In this design both distance and near vision power are located in the central visual area and your eyes will adapt to focus on the area needed to view what you are looking at.

Translating or Alternating Vision lenses

Similar to bifocal eyeglass lenses, these contacts are divided into distinct areas or zones and your pupil will move to the desired zone depending on your vision needs. Typically the top of the lens, which is what you look through when looking straight ahead is for distance vision and the bottom area (what you look through when you look down) is for near vision. However, this can be reversed according to unique vision needs.

Since contact lenses sometimes move within your eye, translating lenses are held in place by a ballast which is an area that is thicker than the rest of the lens or by truncating or flattening the bottom to stay in line by the lower lid. These lenses are only available in rigid gas permeable lens material.

An Alternative Option to Multifocal Contact Lenses: Monovision

Monovision is another contact lens alternative for presbyopia particularly if you are having difficulty adapting to multifocal lenses.  Monovision splits your distance and near vision between your eyes, using your dominant eye for distance vision and your non-dominant  eye for near vision.

Typically you will use single vision lenses in each eye however sometimes the dominant eye will use a single vision lens while a multifocal lens will be used in the other eye for intermediate and near vision. This is called modified monovision.  Your eye doctor will perform a test to determine which type of lens is best suited for each eye and optimal vision.

Are Contact Lenses Right for You?

If you have presbyopia, contact lenses may be a great option for you. Many people prefer the look and convenience of contact lenses over traditional reading glasses. Speak to your eye doctor about the options available to you.

Eye Exams for Contact Lenses

Contact lenses are a great alternative to wearing eyeglasses. An often unknown fact is that not all patients wear contact lenses as their primary source of vision correction. Each patient is different, with some patients wearing contact lenses only on weekends, special occasions or just for sports. That is the beauty of contact lens wear, the flexibility it gives each individual patient and their lifestyle.

If you decide to opt for contact lens wear, it is very important that the lenses fit properly and comfortably and that you understand contact lens safety and hygiene. A contact lens exam will include both a comprehensive eye exam to check your overall eye health, your general vision prescription and then a contact lens consultation and measurement to determine the proper lens fit.

The Importance of a Comprehensive Eye Exam

Whether or not you have vision problems, it is important to have your eyes checked regularly to ensure they are healthy and that there are no signs of a developing eye condition. A comprehensive eye exam will check the general health of your eyes as well as the quality of your vision. During this exam the eye doctor will determine your prescription for eyeglasses, however this prescription alone is not sufficient for contact lenses. The doctor may also check for any eye health issues that could interfere with the comfort and success of contact lens wear.

The Contact Lens Consultation

The contact lens industry is always developing new innovations to make contacts more comfortable, convenient and accessible. Therefore, one of the initial steps in a contact lens consultation is to discuss with your eye doctor some lifestyle and health considerations that could impact the type of contacts that suit you best.

Some of the options to consider are whether you would prefer daily disposables or monthly disposable lenses, as well as soft versus rigid gas permeable (GP) lenses. If you have any particular eye conditions, such as astigmatism or dry eye syndrome, your eye doctor might have specific recommendations for the right type or brand for your optimal comfort and vision needs.

Now is the time to tell your eye doctor if you would like to consider colored contact lenses as well. If you are over 40 and experience problems seeing small print, for which you need bifocals to see close objects, your eye doctor may recommend multifocal lenses or a combination of multifocal and monovision lenses to correct your unique vision needs.

Contact Lens Fitting

One size does not fit all when it comes to contact lenses. Your eye doctor will need to take some measurements to properly fit your contact lenses. Contact lenses that do not fit properly could cause discomfort, blurry vision or even damage the eye. Here are some of the measurements your eye doctor will take for a contact lens fitting:

Corneal Curvature

In order to assure that the fitting curve of the lens properly fits the curve of your eye, your doctor will measure the curvature of the cornea or front surface of the eye. The curvature is measured with an instrument called a keratometer to determine the appropriate curve for your contact lenses. If you have astigmatism, the curvature of your cornea is not perfectly round and therefore a “toric” lens, which is designed specifically for an eye with astigmatism, would be fit to provide the best vision and lens fit. In certain cases your eye doctor may decide to measure your cornea in greater detail with a mapping of the corneal surface called corneal topography.

Pupil or Iris Size

Your eye doctor may measure the size of your pupil or your iris (the colored area of your eye) with an instrument called a biomicroscope or slit lamp or manually with a ruler or card. This measurement is especially important if you are considering specialized lenses such as Gas Permeable (GP) contacts.

Tear Film Evaluation

One of the most common problems affecting contact lens wear is dry eyes. If the lenses are not kept adequately hydrated and moist, they will become uncomfortable and your eyes will feel dry, irritated and itchy. Particularly if you have dry eye syndrome, your doctor will want to make sure that you have a sufficient tear film to keep the lenses moist and comfortable, otherwise, contact lenses may not be a suitable vision option.

A tear film evaluation is performed by the doctor by putting a drop of liquid dye on your eye and then viewing your tears with a slit lamp or by placing a special strip of paper under the lid to absorb the tears to see how much moisture is produced. If your tear film is weak, your eye doctor may recommend certain types of contact lenses that are more successful in maintaining moisture.

Contact Lens Trial and Prescription

After deciding which pair of lenses could work best with your eyes, the eye doctor may have you try on a pair of lenses to confirm the fit and comfort before finalizing and ordering your lenses. The doctor or assistant would insert the lenses and keep them in for 15-20 minutes before the doctor exams the fit, movement and tearing in your eye. If after the fitting, the lenses appear to be a good fit, your eye doctor will order the lenses for you. Your eye doctor will also provide care and hygiene instructions including how to insert and remove your lenses, how long to wear them and how to store them if relevant.

Follow-up

Your eye doctor may request that you schedule a follow-up appointment to check that your contact lenses are fitting properly and that your eyes are adjusting properly. If you are experiencing discomfort or dryness in your eyes you should visit your eye doctor as soon as possible. Your eye doctor may decide to try a different lens, a different contact lens disinfecting solution or to try an adjustment in your wearing schedule.
