Understanding Your Lens Choices
Design, material and treatments are the three components that make up a pair of prescription lenses. It is important to select the right combination of these elements for your particular visual needs and to always consult your eyecare professional.
SINGLE VISION — Contains either a single near or far vision prescription, depending on whether you are nearsighted or farsighted.
BIFOCALS — Combines near (reading a map) and far (driving a vehicle) prescriptions in one lens, with a visible line separating the two fields of vision.
TRIFOCALS — Provides clear vision at three distances–far, intermediate and near. The center portion is segmented into intermediate and near-viewing zones with two visible lines separating these areas.
PROGRESSIVES — Cosmetically the most desired multifocal lens since they do not contain visible lines. The prescription power is dispersed into three areas– distance (driving a vehicle), intermediate (viewing the dashboards) and near (reading a map).
ASPHERIC & ATORIC — Are 30 to 45 percent thinner than standard lenses. When either the outer edges of lenses (high-minus prescription) or the middle of the lens (high-plus prescription) are extremely thick, your eyecare professional may recommend an aspheric lens or atoric lens design that will be more cosmetically appealing, comfortable and will provide the wearer with excellent vision.
PLASTIC — The most popular and economical lens material, available in almost every lens design.
POLYCARBONATE — The most impact resistant material, commonly used for sports, safety, and children’s eyewear. Thinner and lighter than plastic lenses, polycarbonate provides 100% UV protection.
HIGH INDEX PLASTICS — Have the ability to be substantially thinner than plastic lenses, cosmetically more appealing, and are generally more expensive than standard plastic and polycarbonate lenses. Most include 100% UV protection.
