The kind of vision problem that you have determines the shape and type of the eyeglass lens best suited for you. For example, 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. Simply put, the eyeglass lens is a tool used by the experts at our Towson eyeglass store
, Eye to Eye, to focus light appropriately onto your retina.
Progressive Lenses Towson
The single vision lens is prescribed if you need correction for one field of vision, whether for distance or objects up close. Our Towson eyeglass store
offers a number of choices for the single vision lens wearer, including our high-index lenses, polycarbonate lenses, transitions lenses, Polarized lenses, and other sun wear options. Aspherics are ideal for strong prescriptions, because they are flatter and thinner and provide better vision than ordinary lens. Bifocal and trifocal lenses come in many designs, depending on whether you spend hours in front of a computer, play golf, work on cars, etc. The progressive lens does everything a bifocal or trifocal does but without the lines. As technology progresses so do choices in eyeglass lenses.
In the past, eyeglass lenses were made solely of glass but today most eyeglasses are made of high-tech plastics. These new lenses are much lighter, do not 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 Towson eyeglass store
, lighter, thinner, and more scratch-resistant than glass lenses, are Polycarbonate lenses. These eyeglass lenses are shock-resistant and a good choice for people who regularly participate in sports, work in a job environment where their eyeglasses can be easily scratched or broken, and for children who may easily drop and scratch their eyeglasses. Polycarbonate lenses also provide ultraviolet protection. Trivex lenses are made from a newer plastic with similar characteristics of polycarbonate lenses. Lightweight, thin, and impact-resistant, they may 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 Eye to Eye will educate you on the best choice for your particular situation.
