With all the talk about new technology, here's a link to "old technology", which changed the appearance of spectacle wearers, especially those with strong lenses, which had many annoying reflections. Both the wearer and the person she was talking to could see these, and they were very distracting, so thank you Saint Dick Whitney......http://www.dickwhitney.net/AOARCoatingsPage.htm
Anti-reflective coatings have improved over the years. The earliest ones were developed for glass lenses, and for plastic and polycarbonate lenses, new minerals and techiques to coat had to be developed. The durability of AR coatings has improved, and even over the last few years, we have seen better-lasting coats. Essilor's Alize 2 stays clean, doesn't wear off and gives really sharp, clear vision. it's simply the best coating to have on your lenses. And the two year warranty gives peace of mind - not that we need to replace a coat of this quality hardly at all!
