Default Digital Eyewear - Improved Vision Technology

I'm in my late 60s and have seen my vision deteriorate over the past 20 years. Got to the bifocal and then trifocal stage a few years ago. The last time I got new glasses was two years ago. I went to a very good optician that I had done some cabinet and display work for. After discussing the sort of work I did, mechanical and welding and computer, he suggested I consider digital lenses.

With free-form lenses (also called digital high-definition lenses), the fabrication of the lenses from wearer's eyeglass prescription is optimized with computer-controlled surfacing equipment that is much more precise than conventional tools. In fact, free-form technology can surface lenses in power increments of 0.01 diopter (D), compared with 0.125 to 0.25 D increments of conventional eyeglass lens tooling.

The fabrication of some digital, free-form lenses also takes into account how the lenses are positioned in front of the wearer's eyes when in the eyeglass frame, to provide the most accurate lens power and the sharpest vision possible.


After two years of use I rate digital lenses as a must have for most everyone. My ability to see and see through a welding helmet are vastly improved. I can see clearly at ANY distance and ANY angle. It is unbelievable, the difference.

Another tip he gave was caring and cleaning. He suggested ALWAYS cleaning with only lens cleaning wipes. I have followed that tip and after two years including shop use, have NO scracthes or fogging. I use Zeizz Lens Cleaning Wipes, they are $2.97 for a box of 50 at Wal Mart. They are in individual packets about the size of a half dollar. For us older men they fit in your wallet where the condom used to go.

The lenses are about $200 more than standard ones. Figuring the upgraded lenses and wipes for 2 year, 2 per day; it cost me about 40 cents per day for near perfect vision again.
