Eyesight Associates offers most contact brands and can special order brands that we do not have in stock. We prescribe a variety of contact lenses such as soft, rigid gas permeable, bifocal, and astigmatism-correcting lenses. Your doctor will determine which type of lens fits your needs and lifestyle.
If you require contacts, your doctor will choose a contact that is closest to your refraction during your routine eye exam and corneal evaluation. Once your doctor evaluates the contact on your eye and modifies the power, if needed, you will be ready to begin wearing your new contacts.
How Do Contacts Work?
Contact lenses correct the way your eye refracts light. In order to have normal vision, light rays enter your cornea at the front of your eye and focus on a single point on the retina, in the back of your eye.
When light focuses on different parts of your eye, you experience vision problems. People who are nearsighted (myopia), have eyeballs that are too long and cause light to focus on the front of the retina rather than the back. If you are farsighted (hyperopia), your eyeball is too short, which causes light to focus behind the retina rather than on it. Those with astigmatism have irregularly shaped corneas, causing light to focus on several different points.
Contact lenses correct all of these eye conditions by refocusing the light that enters your eye. They sit on the tear fluid of your eye and move fluidly with your eye movements.
