Is there any way to protect my eyes from computer,tv and etc?!

Unless you already need a correction and wear glasses , computer glasses are just a useless scam.

All you need to do is take frequent breaks and keep the monitor at least 28 inches away to help reduce that tired feeling.

There are no dangerous rays coming from monitors or TV , so there is nothing to need protection from.

Thousands and thousands do that all day and don't have visual problems , including myself, for many years.

Optician

They selling computer glasses, which are usually weaker version of reading glasses. You can try reading glasses, 1.0 is the usually the lowest while computer glasses range from. 25-.75 I think. Try looking through 1.0 or lower ( if you can find them) at any stores that sell them, ex: CVS, Walmart, etc.
