Over 140 million people in the U.S. wear eyeglasses, which effectively correct vision by adjusting the way the eyes bend and focus light. Ideally, light rays are refracted (bent) as they pass through the cornea so that they focus on the retina in the back of the eye. In a healthy eye, this means that objects can be seen clearly. However, many people’s corneas have a shallow or steep curvature which causes light rays to focus in front of or behind the retina. Objects may then appear blurry at certain distances or at all distances.
As each person’s eyes are different, so is the extent of correction needed. Prescriptions are measured for each eye so patients can enjoy optimal vision clarity, usually 20/20. Dr. Marcelin is experienced in providing precise eyeglass prescriptions to help patients achieve the clearest vision possible for their individual needs.
Regular eye exams test for the development and progression of refractive errors and help Dr. Marcelin provide a proper prescription if eyeglasses are needed. Exams are also an invaluable tool in the early detection of eye disease, as drastic changes in your prescription may indicate a more serious problem.
