Contact lens exams require special tests that are typically not performed on a routine eyeglass exam. Contact lens exams require a fitting of the contact lens according to the parameters and curvature of the cornea.
SPECIALTY CONTACT LENSES
CRT, or Corneal Refractive Therapy, is a non-surgical option that helps correct nearsightedness without the daytime use of contacts or glasses. CRT lenses are worn at night, and correct the curvature of the cornea while sleeping so you can see clearly during the day.

Keratoconus is a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape. This cone shape deflects light as it enters the eye on its way to the light-sensitive retina, causing distorted vision.
