Tim, there is something a little weird about those sunglass lenses, or at least with the way they are described in the news release, so since I can't call the company until tomorrow, I'm asking one of the smartest guys I know, you.
They say in the news that the lenses can be rotated, and that they are polarized, and that you can have prescription lenses in them.
Well, I say there is no other product like theirs, simply because what they claim, as the news release is written, is not possible for either prescription lenses for people, like me, with astigmatism.
Nor is it possible to rotate a polarized lens, and have it remain polarizing. Both are pretty simple and basic optical principles. In both cases the lens must remain on the same axis, or the person with astigmatism ain't a gonna see too well, and with the polarized lens, turn it 90 degrees, and it just ain't a gonna polarize.
If anyone doesn't believe me, ask any eye doctor, or opthamologist, or about the polarizing, any kid in a camera store should know.
One other thought, a little more minor, to rotate the lenses in the frames, seems to me you can only have one lens shape.....round. Round sunglasses used to have a big market, John Lennon style, but it's not that big now. I've been in both the sunglass business for about 15 years, and the camera and optics business for over 20.
I suppose they may have some double or triple lens system with something inside rotating, but it can't be as simple as the news sounds.
"To our knowledge there is no sunglass product like ours for sale anywhere in the world. By simply rotating the lenses within the ultra
thin frame the wearer can choose from a variety of colors including amber, blue, green, grey and rose. The technology also allows one to go from lighter to darker within the same color. There are no replacement lenses to purchase, replace, carry or interchange. The sunglasses can have either non-prescription or prescription lenses. " |
