Reliable Comfort &
Visual Clarity

If you wear contact lenses, you know how convenient they are and their ability to provide visual clarity. While contact lenses may look small and simple, the way in which they aid your vision can be quite complicated. Contact lenses are medical devices that need to be fit and evaluated annual with a Contact Lens Exam to make sure they aren’t causing serious risks to your eye health.

Our eyes change subtly over time, and prescriptions may need to be adjusted depending on the lens types or even the brands. Just because you have worn the same brand for years doesn’t mean you will be able to forever. Having a proper eye exam is key to maintaining the health of your eyes. Our doctors are dedicated to helping you find the perfect pair of contact lenses for your eyes and providing you with the necessary information you will need to utilize your contact lenses properly.

At Optical Illusions: An Optometric Practice, our contact lens exams are designed to not only ensure that your contact lenses are right for you, but that you are right for your contact lenses.

What is a
Contact Lens Exam?


Compared to a regular eye exam, a contact lens exam involves gathering additional data measurements that help determine the shape and size of your eye’s surface. These measurements will determine what kind of contact lens will work best for your eyes. 

The Doctor optometrist will use a special device called a Pentacam AXL Wave that will take advanced measurements of the front surface of your eye to determine the most appropriate base curve and diameter of a contact lens for you. This was previously done with 3 separate devices called a keratometer, topographer, biometer.

Our doctors determine if you can produce sufficient enough tears to keep your contact lenses moist and lubricated. If your tear film cannot produce an adequate quantity or quality of tears, then contact lenses may not be safe or comfortable for you to wear contacts for extended periods of time.

A slit lamp is used to evaluate the overall health of your cornea. This tool will magnify the view of your cornea up to 40x and help our doctors determine if your lenses are too loose or too tight, and if they are causing any oxygen deprivation to the cornea. If you already wear contact lenses and are experiencing any kind of discomfort, this procedure can help determine what issues that your current pair of lenses are causing to your eyes.

Our eye doctors will check the health of your meibomian glands, or oil glands, that sit at the base of the eyelid margins. Blockages of these glands can cause inflammation and hordeloums, or styes which decrease the comfort and longevity of contact lens usage.

Some patients have irregular corneas caused by injury, dystrophies, or degenerating conditions and cannot wear regular soft contact lenses. Many of our doctors are able to fit a variety of specialty contact lenses that could be the solution for those specific needs.

These special lenses include rigid gas permeable (RGP) lenses, hybrid lenses, scleral lenses, bitoric lenses, and custom soft lenses.
