Transitions Photochromic Lenses & 39DollarGlasses.com

Two reviews here...
1st 39DollarGlasses.com. I very much like this company. You really can buy decent glasses for $39.00. Because glasses are very personal, I was hesitant to buy a pair over the Internet. I heard good things elsewhere. In addition 39DollarGlasses.com offers a good return or exchange policy. So when got a scratch in a lens of my old glasses, I thought I'd give it a try.
I measured my old glasses to ensure I got a good fit, entered my prescription and selected frames. One week later my new glasses were in my mailbox. Great fit. They look good. The lenses were wonderful.
I opted for Transitions Lenses; lens that darken in the sun. They are nice, but not everything I'd hoped they would be. I will still need a pair of sunglasses. Transitions Lenses are activated not by visible light, but by UV light. This means that...
  • The lenses go dark on a cloudy day at noon since UV travels though clouds.
  • The lenses don't go very dark while driving on a sunny day since windshields block out UV.
  • The lenses won't go dark at sunrise or sunset, even if you are driving into the sun.
