Sleep ZM Blue Light Blocking Glasses for Sleep - 99% Amber, Black Wayfarer 87% fotocromático

I have had these glasses now for over 2 years and they continue to hold up and work great, with no scratches, and still do the job. Look great and feel great. I wear these glasses everywhere I go; they even help with nighttime driving. perfect for work when staring at the screens for 8 - 10 hours a day. I highly recommend these glasses to anyone thinking about saving your eyes these are the best at a great price!Just bought a new back up pair. Best glasses I have ever owed!

I was a bit skeptical about the claim that these glasses block 85% of blue light since normally yellow glasses can only block out up to 65%, but these glasses really do block out 85%. These glasses are extremely versatile and you can wear these glasses anytime, anywhere and they will protect the area around your eyes from harm. I highly recommend these glasses for anyone looking for eye protection, especially protection from blue light.

to be honest, i couldn't believe my eyes when used them.only problem i have is the glass is soft and scratch easy.

I received a pair of glasses that were yellow tinted blue light blocking but had no sunglass tint or transition. I think I received the right item as the packaging described transition glasses. I returned the glasses.

Unusual glasses, but they work well in bright sun to overcast days. They transition pretty dark for daylight, but stay a little too dark for nighttime use. Polaralization and yellowish lenses make everything with a reflection like car windshields and puddles look the color of automobile antifreeze. But, I use them for bike riding year round and they are nice because even thin black ice shows up real well.

I’ve been sitting in front of a laptop and or tablet for up to 16 hours a day for the last 12 years. I started to notice that I was waking up every morning with a headache and that slight headache could last throughout the entire day. A co worker and I were talking and he told me about these glasses. I immediately ordered these and I haven’t had a headache since the day I started wearing them. This is a must have for anybody who works in front of a computer. The best part is you can use them day/night/raining

Started breaking apart as soon as the return window closed.... worked fine for the first 3-4 weeks.. they are light weight but after that things started looking south

I got these because my light sensitivity has been getting worse, and to hopefully reduce migraines.Positives: They're light weight. You don't feel them much. You can wear them for long periods of time comfortably.For the computer: ★☆☆☆☆I was hoping to use them for my job, which is computer work. But the right lens is blurry in spots and warps your view. So while looking around the screen, I start to feel nauseous because of the warping. And text will be blurry in certain spots, which is annoying. So they don't work for PC. The left lens (oddly) is fine. I returned the first pair for a replacement, but the replacement has the same issues in the right lens.For sunglasses: ★★☆☆☆The blurriness and warping isn't pronounced enough to cause problems when you're looking at things at a distance. …
