Whether you're new to glasses, or have been wearing them for years, you can benefit from the newest lens styles and materials. This article will define the varied lens materials, and show you which is best for your individual prescription.
If you’ve needed to buy glasses lately, you’ve probably noticed that there are many more lens material options available than ever before. Should you still wear glass lenses? Do you really need lightweight lenses? Why do lighter lenses cost more? Can you get bifocals in thinner materials?
Whether you’ve been wearing glasses since childhood or are a first-time wearer, this guide will help you understand your options so you can make the best decision for your lifestyle.
The Three Styles of Lenses
Single vision lenses can correct for distance vision or near vision, but not both. The reading glasses sold at drug stores are all single vision lenses and correct only for near.
Bifocal lenses correct for both distance and near vision in the same pair of glasses. Bifocals are available in lined or non-lined styles. Most people over forty years old will need bifocal lenses.
Trifocal lenses have three focal areas divided into lined segments: distance, intermediate, and near. Trifocals are useful for a wide range of visual needs, including computer use.
The good news is that no matter what style of lens your eye care professional recommends, it’s available in a variety of materials to best suit your needs.
