Infield Terminator UV-400 Safety Glasses for Blue Light and UV

One of the biggest problems with glasses like these is that you don't know how much light is actually getting blocked. Thankfully these glasses come with proper safety glass markings; 2-1.7 GA 1 FT K. In simple terms, these should let in about half of all visible light, provide great protection from UVB (filter >99.99%), some protection from UVA (filter >93%), and unknown amounts of protection from IR and UVC. I tested these glasses with a UV meter and a 395nm UV source (10W power, 1.3W radiant intensity.) The UV meter showed a reduction of >99%, or better than spec for that wavelength. Other tests for these glasses showed reductions over the whole blue light range of 99.8%, which is excellent. They fit closely to my face, are comfortable and adjustable, and do not let light in through the side like most other glasses do. In short, these are excellent glasses for both blue light and general safety. ------- For the curious, a technical explanation of that marking: 2-17 is a scale number in the DIN standard EN:170; if your glasses are marked 2-17 they must transmit max. 0.0003% of any wavelength from 210-313nm UV, 7% of any wavelength 313-365nm UV, and between 43.2% and 58.1% of any wavelength from 365nm to the "IR range", which is not numerically defined. Other markings on the glasses included: "Z87+" (ANSI impact protection rating) and the name of the manufacturer.

I purchased these based off of a suggestion i read on reddit after being overwhelmed by the marketing of blue light blockers everywhere. I decided to give these a chance because they were a good price point and seemed good quality. I use them as part of my nightly routine and they've improved my sleep and rest significantly. The visibility is great. I appreciate that they wrap around blocking even more light than some of the more expensive brands do. They maybe look a little silly as their appearance is not stylish but i don't mind it. I love the adjustable fit as well. If you have longer hair there is something to be aware of. There are two prongs at the sides where longe hair can get caught on and snag. My solution to this is some painters tape of them and no issues after that. Again, the look isn't elegant but for the price and the quality it's hard to beat.

Glasses help with eyestrain when working on computer; clarity is good, and they're comfortable; they block a substantial amount of blue light. Orange tint might dissuade some from using them.

I have some bright blue LED's I test the blue blocking capabilities of various blue-blocking lenses with. With the Uvex Skypers and Proteges (SCT-Orange tint), the blue blocking is profound, near complete. If I'd rate the Uvex as profound for blue blocking, then I'd rate the Infield Terminator lenses at insane. Not complete, but definitely at least a small but noticeable notch above the Uvex lenses. These lenses are a bit darker in general than Uvex which could account for it, though I would suggest as mentioned in the headline, this can be both good and bad. If I'm driving in the daytime, green lights (which seem to put out tons of blue light) are nearly invisible unless I'm paying very close attention. Also, the sensation can border on virtual reality if you're not used to the amount of blue blocking, whereas I did not get that sensation with Uvex SCT-Orange lenses. These lenses and Uvex SCT-Orange lenses each have their merits (and considerable blue blocking either way). The cost is reasonable enough that the best thing to do is try one or the other for yourself and see which works best. I have both Uvex glasses and these, and I've noticed both seem to work better in different situations. Regarding the lens tint, the main picture seems to suggest this is a multi-tinted lens. It's not. Rather, it's a uniform fairly dark orange, almost the exact color of an amber construction strobe light. I have a fairly large head, and these did pinch a bit at first. They seemed to expand to my head with a bit of time, though perhaps a "luxury" spring hinged version of these may be in order. The nosepad is a bit strange but functional. When I received these, the nosepad was completely bent one way, but quickly adjusted to a central position. As I wear these, the nosepad seems to self adjust to the shape of my face, no complaints there. Note that these are essentially safety glasses and thus have safety frames, not cheater-reader frames. All in all, these are exactly what they claim to be. Thus, there's no hesitation giving these 5 stars.

These glasses do a great job of filtering the blue light, they are comfortable to wear and I really like how they can be adjusted to fit your face. Good value for the money!
