High Definition Lenses Offer Clearer Vision

If you wear glasses, you probably assume all glasses are about equal - as long as they match your prescription, you’re good to go. The reality is that new techniques in making lenses means all glasses are not created equal. High-definition is not just for TV and the movies. Now you can get HD glasses, too.

No Two are the Same
Differences in glasses start with the differences between your eyes. Whether you’ve noticed or not, no one’s face is symmetrical – the two sides are slightly different. The same is true of your eyes. One may be slightly higher or farther out from your nose. Those things affect the way your glasses work.

In addition to the differences in the position of your eyes, each of your eyes is unique. Just like fingerprints, no two eyes are exactly the same. Tiny differences in the surface of the lens and cornea – two parts of the eye that focus light – mean that each of your eyes needs its own prescription. It also means that even though other people may have the same basic prescription for glasses that you have, the way their eyes actually see through their lenses will be slightly different.

Your basic glasses prescription is intended to correct your nearsightedness, farsightedness, or astigmatism. But the slight variations in your eyes may mean that you still don’t see clearly even with the right glasses prescription. High-definition lenses are working to correct that problem, starting with clarifying the lenses themselves.

Free-Form Lenses
“Free-form lenses” are made using new techniques that reduce the slight variations that can occur when lenses are made. These lenses are also sometimes called “digital lenses”. In addition to making the lenses to match a general prescription, manufacturers also take into account where the lens sits in front of your eye in your chosen frames, and what the angle is between your eye and the lens when you look up, down, and to the sides. This precision can help reduce glare, starburst, and halos around lights at night. The lenses can also give sharper vision and better peripheral or side vision.

If you can find a pair of eyeglass frames that you like and need prescription lenses (these are usually the most expensive aspect of eyeglasses), you can get really cheap prescription eyeglass lenses at www.replacementlensexpress.com. You can get single vision for $25 and then add a sunglass tint for just $12, and they do ANY COLOR.

The delivery time within the states is usually 2-5 days (they are made in Connecticut).

They do stock eyeglasses, but they aren't up on their site yet (old store, new to the web) so if you shoot them an e-mail telling them what type of frames you're interested in, they can sell them to you at wholesale. You might even want to send them the link to these glasses and they can tell you a price.
