Interesting new development for us 4-eyed folk... electronic focusinglens
This is rather interesting, glasses that can be switched from bi-focal
to regular lens in milliseconds, either manually or automatically. Price, according to demonstrator, will carry a 'slight' premium over blended lenses in a high quality frame. Probably won't see these on Zenni anytime soon....  http://www.youtube.com/watch?v=buLnHrBDCao Jon |
