Vision Correction: 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 eye care 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 eye care professional may recommend an aspheric 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.

LENS DESIGN

There are more lens options today to meet your visual needs and activities, so take careful consideration when selecting a lens for your lifestyle.

LENS TREATMENTS

Anti-Reflective (AR)
AR lenses reduce reflections and glare making it easier to see especially when driving at night. Since reflections on the front surface of the lens are virtually eliminated, your lenses will appear invisible, allowing others to see your eyes clearly.

Polarized
Used to block glare, polarized lenses are a smart choice for prescription sunglasses and come in a variety of lens materials and colors.

Scratch Protection
Protects the lenses from everyday wear and tear. Polycarbonate, high-index and several new plastic lens materials have scratch-resistant protection.

Photochromic
Versatile lenses that change from light to dark and back to light by responding to UV light and temperature. These lenses are available in plastic, polycarbonate and high-index plastic.

UV Protection
Making sure your lenses include ultraviolet protection may prevent skin cancer around the eyes, cataracts, and longterm eye damage. While lens materials, such as high-index and polycarbonate, provide UV protection in the material itself, plastic lenses may require an added UV treatment.
