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

Great glasses, fit really well and transitions work really good. Happy with them

These glasses are lightweight, conform to the shape of your face, and stay in place. They darken quickly in sunlight and lighten just as quickly which means one doesn’t have to put on and take off when going inside and out. i haven’t challenged their protective ability yet.

Good light weight safety glasses. They do NOT get that dark. There is a slight warping of vision but i only notice it when i am trying to open a tumbler style (Master lock) in bad lighting. it's not noticeable when driving. I don't notice them changing tint but if i compare them in and out of the sun they definitely change tint.

Stylish, comfortable, and great sun protection

These are very comfortable, so comfortable I forget I'm wearing them. They tint just enough for most conditions. I will definitely by another pair when I need them. I have worn real glasses for years and the people on here that say these don't tint fast enough or dark enough have never worn real photochromatic lenses. The temperature does play a part as when it gets cold they get darker. That's just the chemical used in them that makes them darken.

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)

Realmente me gustaron mis gafas de seguridad, son confortable y buenas al momento de estar a la luz del sol

I’ve had several pairs of different brand photo-chromatic safety glasses. I usually end up getting new ones when the lenses get too scratched up. I bought this brand in November and they darkened very nice. In February I got to my office and let them fall on my desk from about 4”. The frame above the right lense broke. I’m not sure how they get a safety rating of z87.1 when they brake that easy. I have never experienced any safety glasses breaking in the 23 years of industrial work. I would not recomend these.
