Contact Lenses are great Alternative to wearing Eyeglasses

Contact lenses

As a great alternative to eyeglasses, some patients wear contact lenses. Our clinic offers great options for contact lenses near you, and we serve the surrounding area, including Lewis Center. The contacts are not a patient’s sole source of vision correction. Each patient is different, and chooses when and where to use their contact lenses. Some choose to wear them to work, and others choose to wear them during special events. The wonderful thing about contacts is that the patient is able to choose and customize their lifestyle to their eye wear.

To better serve you, our staff at Professional VisionCare will do a comprehensive eye exam before prescribing contact lenses. The comprehensive exam includes a check of your eye health, a look at your general prescription, and then a contact consultation. If contact lenses are your choice, you will have a contact lens consultation, which involves a measurement as well to decide a proper fit. Contacts should fit comfortably and properly. Our staff will then make sure you know the proper contact lens hygiene and instruct you on contact lens safety.

The Importance of a Comprehensive Eye Exam

Whether you have vision problems or not, having your eyes checked regularly ensures proper eye health, with no developing eye conditions. A comprehensive eye exam checks both the general health of your eyes and your visual acuity. During this exam the eye doctor will decide your prescription for eyeglasses. This prescription alone is not enough for contact lenses. The doctor will check for any eye health issues, such as dry eye, 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. The result is contacts are more comfortable, convenient and accessible. This is why the optometrist will discuss some health and lifestyle factors before suggesting contact lens options that suit you best.

Some 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 may have specific suggestions for the right type or brand for the best comfort and fit for you.

If you would like colored contacts, let your eye care provider now. For patients over 40, and having problems seeing fine 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

Contact lenses are not a one size fits all item. To fit your lenses properly, the optometrist will need to measure your eye. Improperly fitting contact lenses could cause discomfort, blurry vision or even damage the eye. The measurements your eye doctor will take for a contact lens fitting include:

To ensure that the curve of the lens properly fits to the curve of your eye, your doctor will measure the curvature of the cornea (the front surface of the eye). The curvature is measured with a keratometer which determines the proper curve for your contact lenses. If you have astigmatism, the curvature of your cornea is not perfectly round. A “toric” lens, which is designed specifically for an eye with astigmatism, would be used to offer optimal fit and comfort. 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.

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 important if you are considering specialized lenses such as Gas Permeable (GP) contacts.

One of the most common problems affecting contact lens wear is dry eyes. Contact lenses that are not kept properly hydrated become dry causing the eyes to become itchy and irritated. If you have dry eye syndrome, your doctor will want to make sure that you have enough tear film to keep the lenses moist and comfortable. If not, contact lenses may not be a good vision choice.

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. Another way is by placing a special strip of paper under the lid to absorb the tears, seeing how much moisture is produced. If the tear film is weak, your eye doctor may recommend certain types of contact lenses that are more successful in maintaining moisture.

You may be asked to try on a pair of contact lenses to feel if the fit is comfortable. The doctor, or assistant, will insert the lens. You will 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, these contact lenses will be ordered for you. Your eye doctor will also offer care and hygiene instructions including: how to insert and remove your lenses, how long to wear them, and how to store them, if relevant.

To assure that your eyes are adjusting properly and your contacts fit well, you may be requested for a follow up appointment. Visit your eye doctor if you experience any dryness or discomfort while wearing your contact lenses. Your eye doctor may decide to try a different lens, a different contact lens disinfecting solution or to try adjusting your wearing schedule.
