The eyeglass lens is a tool used by the experts at our Ashton-Sandy Spring optical store
, Quality Optical of Olney, to focus light correctly onto your retina. The type of vision problem you have is what determines the shape and type of eyeglass lens that is best suited to your needs. For instance, a lens that is concave, or curves inward, is used to correct nearsightedness, while a lens that is convex, or curves outward, is used to correct farsightedness. A distortion in the shape of the cornea, or astigmatism, is usually corrected by a cylinder shaped lens. The single vision lens is prescribed if you need correction for one field of vision, whether for distance or objects up close. At our Ashton-Sandy Spring optical store
, we offer a number of choices for the single vision lens wearer, including our high index lenses and polycarbonate lenses. As technology advances, so do choices in eyeglass lenses.

Eyeglass lenses used to be made solely of glass but today most eyeglasses are made of high-tech plastics. These new lenses are much lighter, don’t break as easily, and can be treated with a filter to protect your eyes from damaging ultraviolet light. One modern eyeglass lens recommended by the experts at our Ashton-Sandy Spring optical store
are polycarbonate lenses, which are lighter, thinner, and more scratch-resistant than glass lenses. These eyeglass lenses are shock-resistant and a very good choice for people who participate in sports on a regular basis, work in a job environment where their eyeglasses can be easily scratched or broken, and for children who tend to drop and scratch their eyeglasses. Polycarbonate lenses also provide ultraviolet protection.
Made from a newer plastic with similar characteristics of polycarbonate lenses, trivex lenses are lightweight, thin, and impact-resistant. Trivex lenses have also been known to result in better vision correction than the polycarbonate lenses for some people. High index plastic lenses are designed for people who require strong prescriptions but these eyeglass lenses are lighter and thinner than the standard, thick "coke bottle" lenses that may otherwise be needed. Whatever your situation, our educated staff at Quality Optical of Olney will educate you on the best choice for your particular condition.
