Global Vision GTR Hercules 7 Auto-Darkening Photochromic Safety Sunglasses Black Frame G-Tech Red Lens ANSI Z87.1+

These safety glasses are very comfortable to wear and stay on the nose quite well even in warm weather when sweating. The color of the lenses is very easy on the eyes and the photochromatic lenses change quickly making these wonderful for use when working outside in the sun light and inside under artificial light. Too soon to be able to say something about quality as I have had these for only 2 weeks, but so far these seem quite good. All in all very pleased, well worth the money

Fit and look great. Works as advertised. Bought more than 1 pair

Strong and work well as sunglasses, but it will dig into your nose after wearing it for several hours.

Very good optical clarity. Frames are lightweight and sit comfortably on the nose. They wraparound nicely to keep wind out of my eyes when riding my motorcycle. The red lense color looks cool, and is amazingly is very clear and not red at all looking through them. Very good in low light however in bright sunlight the photochromatic feature doesn't get dark enough, but it works as well as other photochromatic glasses I have purchased for double the price. I think photochromatic technology in general is the reason they don't get really dark. For $34 you can't beat these glasses.

Don't get dark enough on sunny days otherwise a good pair of glasses

I bought these to wear for motorcycle riding. I wear a 1/2 helmet, so having the stems not be excessively long was important to me. These fit well, sit comfortably on my face, and the transition from dark to light and back is pretty quick. They do very well in bright sunlight, yet lighten enough to wear well past dusk/sundown. While they don't quite go clear, the minimal tint they have at sundown isn't enough to cause issue. Very happy with these, and the other pair of Global Visons I own. Great for motorcycling!

Perfect

Not only do these not transition but they arrived with two large scratches on one of the lenses. For this much money they should be scratch resistant and arrive in better packaging.
