VIEWS FOR 20/20 by Dr. Mark Skowron and Dr. Michelle Skowron HOW DO EYEGLASSES WORK? Like the lens and cornea in your eye, eyeglasses work by bending light to help it focus correctly on the retina. Refractive errors-which cause nearsightedness, farsightedness, and astigmatism-are corrected with different types of eyeglass lenses. Refractive errors occur when the eye's shape prevents light from focusing properly on the retina. Eyeglasses work by adding or subtracting focusing power to the cornea and lens. There are three types of lenses used in eyeglasses. Concave lenses are thinnest in the center of the lens and are used to correct nearsightedness. Convex lenses are thickest in the center and are used to correct farsightedness. Cylindrical lenses curve more in one direction and are used to correct astigmatism. At SKOWRON EYE CARE we offer a large selection of high-end designer frames, eye glasses and sunglasses. We also offer a wide variety of contact lenses that are guaranteed to suit your individual needs. We can help you select the style, shape, and color of eye glasses or sun glasses that are right for you!
