Different Eyeglass Lens Options

Modern eyeglass lenses have a number of special features that eliminate common problems among wearers. They protect your eyes from harmful ultraviolet (UV) rays, reduce glare and prevent damage when you throw them in your purse or pocket. Many of these features are available in combination, meaning you can enjoy the benefits of several lens options in one.

High-Definition

• According to optometrist Gary Heiting, OD, at All About Vision website, high-definition eyeglass lenses give some wearers clearer vision than other lenses. They minimize glare at night and help users gauge the distance of objects against backgrounds. They come in two main types: free form, which are the most popular kind, and wavefront lenses, which use LASIK eye measuring technology to create lenses.

Transition

• Transition lenses, also known as photochromic lenses, are light and clear indoors, then darken when exposed to sunlight. In other words, in bright conditions they turn into prescription sunglasses. They are popular choices for adults and children who like to spend time outdoors, and they eliminate the need for separate sunglasses for many people. According to Heiting and The Vision Council, nearly one in five lenses sold in the U.S. are photochromic. These also offer UV protection to prevent retinal damage from the sun.

Scratch-Resistant

• If you're worried about dropping your glasses or forgetting about them in the bottom of your purse, scratch-resistant lenses may alleviate some of your problems. They are covered in a protective coating that reduces the incidence of scratching, especially when coated on both sides. All About Vision states that this is especially helpful for kids, whose lenses are prone to scratches during playtime.

Anti-Reflective

• If you've ever been driving at night and noticed the glare of headlights that make it difficult to see the road, you've experienced glares and reflections--a common problem that anti-reflective lenses correct. They have a coating that allows light to pass through the lenses instead of bouncing back and causing glare. This enhances clear vision and allows others to see your eyes instead of their reflection in your lenses.
