If you spend most of your day staring at a computer screen, you'll want a UV and blue light filter to protect your eyes. The problem is that many blue light and UV filters darken the monitor display, reducing brightness and graphic clarity. This is not the case with MOSISO's blue light filter and screen protector, which retains 95% of the screen's original brightness. That's why it's the best choice when graphics are key, such as for graphic art and gaming purposes.

Tired of that nosy office neighbor that's always trying to spy your iMac monitor from the side? Then this is the screen protector for you!
