These are for night time btw

They're real and working unlike many other falsely advertised glasses, but they don't block 99% as claimed (because then it would turn blue colors into gray and block green colors as well).

I tested it, blocks about 50%-70% of blue light (darkens it and/or turns it green).

It's also comfortable and more premium than most glasses at this price, came with microfiber cloths.

As this filters out 99% everything goes orange, if you need to distinguise different colours go for something lower like 50%. I love using this especially on days i have headaches or i'm tired it takes away alot of strain and eye fatigue, allowing me to stay on my computer screen for 8+ hours per day. I don't wear glasses but this is quite lightweight you barely notice it.

Good product. It does give the feeling of resting the eyes while working at the computer

Anti-blue effect is almost too much (have to get used to it first), well built, lightweight glasses, packaged carefully. Paper box came bit crooked, but glasses were protected. Plastic, though normal quality, feels comfortable, i really like it.
