Alpha Omega AO2 Auto-Darkening Photochromic Motorcycle Sunglasses Black Frame, Clear-to-Smoke Lenses, Unisex, ANSI Z87.1 Certified

Fit is very comfortable. Well made. Photo chromatic changes are subtle in each direction and effective. Glad I bought them. Recommend.

I used to buy the "sets" of sunglasses, the ones with, clear, dark and amber colored lenses. And of course, they would lay around in the top case of my motorcycle collecting scratches waiting to be transferred to one of my other bikes, or until they got crushed or scratched so bad I hated using them. Then I found these photo-chromatic "motorcycle" glasses with lenses that darken or lighten as the day changes to night. This is now the third set of these glasses I own. I keep two pair in the Harley for my wife and myself, and another in the BMW RT which I generally ride alone. I wear an Extra-Large helmet on my extra-large head and these glasses fit almost perfect for me. They're snug enough to stay in place without gripping so hard they become annoying. They're made from hard plastic and don't flex much, so they my not work for everyone. If you have a head size much off the average for x-large, you may find them uncomfortable or loose. Unlike most motorcycle glasses, these DO NOT have a foam seal around the inside of the lenses that allow enough air to keep your eyes from fogging but not so much that they dry out. I really like this feature and am saddened to find this particular model of these glasses does not have it, especially as these are billed as "motorcycle" glasses. Other than this one feature, these seem to be exactly the same as my others. They do however, like my others, have the soft rubber nose piece the seem to stay comfortable. The photo-chromatic feature works well but takes a little getting used to. I have found that the view through the lenses kind of remains the same whether it's dark or light. They always seem lightly shaded to me whether it's day or night. I know though, that in bight sunlight I can take them off and see they are dark and at night they become almost clear. I've been using these glasses for near two years now and they are still in excellent condition. Maybe they are more scratch resistant than others or maybe I'm just more careful with them (and I am) because I like them and they're not exactly cheap. Oh, and I think they look great too, but sadly I'm lowering the rating due to no foam wind protection around the lenses.

I expected them to transition a little bit darker! I still have to change to a second pair of glass!

Reasonably dark in sunlight and gets clear when the sun goes down

I've used Bobster's for ages, but for some reason they've been breaking lately at the hinges, so been looking for a new type of glasses for my bikes. These fit me great (I wear a large size helmet, and have what's called a "roman" nose) and are very comfortable for riding, no slipping, and good but gentle pressure on head. I really like the fact that I don't really have to change the lenses from day to night. That said, they don't seem as dark as my older glasses but seem to be okay as long as I'm not riding exactly into the sun. My one issue with these for being my "main" riding glasses is that they don't seem to be properly sealed or vented when going speeds over about 60 mph, and I get too much wind in eyes that starts tearing (I also wear contacts that make my eyes quite susceptible to wind). I like these for riding my Vulcan as I rarely go on the interstate with it, but they are not sealed enough for my Thunderbird. They seem to be well made so far, but I'll be reporting back if they break anytime in the future.

I needed a new pair of safety glasses and these met expectations easily. The frames were light and the wrap around design kept these on your eyes while working with ease and felt really comfortable to wear for long hours. In addition, I'm sometimes in humid areas and these didn't fog up like my previous safety glasses, which was great. Another great feature are the transition lenses. Sometimes I need to step out to make a call and could just keep these on to act as sunglasses. In addition to the durabilty, comfort, and design, these were really a more stylish pair of safety glasses. Definitely checked all my boxes.

Fits well and feels protective. I use them as indoor safety glasses, but I've tried them outdoors a bit just to see the lens transition, and I didn't see any shift in tint. I work with hot glass and I was curious to see if they would tint while looking into 2000 degree reheating chambers, but they didn't seem to be affected by that either. I think they need more time under exposure to work. I think for $30 if you actually use them for riding they're probably a good deal, but if you just want safety glasses you can get something considerably cheaper.

I ordered these glasses to wear while biking. I live in an area of the county where there are tons of bugs present during early morning and dusk rides. Constantly clearing them out of my eyes and mouth. I initially was wearing sunglasses, but the sunglasses were too dark for evening rides. These glasses are perfect for my use case. Not only do they auto tint via the photochromatic properties of the lens, but they keep my eyes shielded from critters while riding. As the sun sets, the lens changes back to clear - perfect! Highly recommend for motorcycles although I haven't tested at speeds that fast. For mountain bikes and e-bikes, they are perfect!
