Glasses and contact lenses improve 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 (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.
Glasses and contact lenses correct these refractive errors. Prescriptions are measured for each eye so patients can enjoy optimal vision clarity. Eyewear may be used for certain activities, such as reading for farsighted (hyperopic) patients and driving or watching television for nearsighted (myopic) patients, or may be worn at all times.
Regular eye exams test for the development and progression of refractive errors and help your ophthalmologist provide a proper prescription if eyeglasses or contact lenses are needed.
