Has anyone used them??? If so, did they work as advertised? I saw them at a trade show and was curious.
Is this what you're talking about?
that is a great idea for glasses, i just might bite the bullet on that price and get some. i am majorly color blind and have to rely on texture , it gets tough although i funtion better than most color correct folks. i have learned to spot issues from very far away, but i cant say it is easy. thanks for posting this find, it will help me in the future.
