Global Vision Hercules 7 Safety Sunglasses Photochromic Auto-Darkening Clear to Smoke Lens ANSI Z87.1

I’m very impressed with these safety sunglasses. The photochromic lenses adjust quickly from clear to smoke depending on the lighting, which makes them perfect for both indoor and outdoor use. They feel comfortable and lightweight, yet still provide great eye protection. The fit is secure and they stay in place even during active work. The build quality is solid and the lenses are very clear. Overall, these are reliable, well-designed safety glasses that work great in changing light conditions. 👍

This a comparison review with the 3M brand (pictured on the right). Much better build quality than the 3M Securefit Smart lens (SF613AS) and cheaper too. The 3M are temples are very flimsy and already breaking thus why I'm replacing them. This safety glasses fit me better on my face and they are pretty light. I am a 185 lbs 5' 11" male. The Global Vision are slightly darker in the sun. However, they take like a minute longer to clear up in the shade. These are not sunglasses so need to manage expectations. They turn to smoke color in full sun, not as dark as real sunglasses. They are dark enough where I don't have to squint my eyes when I'm working outside on the yard. I cannot comment on their durability since I just got them but I highly recommend them based on functionality and comfort.

Love the glasses

Why did you pick this product vs others?: Great, fits well, comfortable all day, doesn't touch my face. Makes bright screens and work between in and outdoors easier. I get migraines less with these compared to the crappy ones my work gives me. No issues after a 50 hour week and getting sprayed in the face with oil. 5/5 Tint isn't super dark and takes a little to transition but not bad. They look good on me too.

Useless. The auto darkening does very little - if anything at all - and, you know, that was the reason that you purchased them. I am aware that they do not work in cars because the glass filters the UV rays that 'activate' the darkening process. The ad photos suggest a high level of darkening which turn out to be a lie - hardly any at all - seriously, and they even have tint in a dark room. Again, I am not sure that they darken at all. And then the nose bridge - it is so large, it is in your field of view - and that by itself makes these auto tinting glasses useless (see photo). And on top of that, they cost $40 and provide zero value. They do look good IMO, but... I sent them back.

I'm very happy with these. No they are not sunglasses. But they tone down the sun enough you won't be squinting. Use them daily for work. Plan on purchasing a few more pairs. They do take a few minutes to adjust to brightness, but as expected.

I needed a comfortable pair of quality auto tinting safety glasses for riding my road bike early (just before sun up) that would tint after the sun rose. I also needed them to double for when I play pickleball with my wife (after the sun has already come up ;0) and these fit the bill all around! They're comfortable and the tinting is gradual and just right. Initially I highly recommended these but since then the side piece that goes behind my left ear broke as I was removing them from the microfiber storing pouch! Obviously this past of the stem (at the halfway point) is the weak point in the plastic frame. After spending $40 on these and them only lasting seven months, I'm shipping for a new pair and a new manufacturer. Perhaps I'll settle for a $10 pair they'll probably hold up equally as well and at that rate I can afford to go through four pair :0)

I have had them in use for a week and they are good. Better than my company issued safety glasses. More comfortable too. I can pretty much wear them all day. As for the tinting, it does work. Not as dark as true sunglasses, but noticeable. Helps when I have to go between buildings.
