light Blocki ng that reduce light from the lap top screen
Berrylands KT5
DESCRIPTION
Hello, I work hard at the university, read a lot, many hours on the computer, and I think it is good if I have glasses, not for eye sight, but that reduce the light from the screen. Night mode is not enough because big parts of the screen are still bright and the light is sometimes not strong and it is bad for the eyes.
