I have sensitive eyes as well and do a lot of work at night so looked into getting a screen protector like the kind used on the old CRTS, but they were too bulky, somewhat costly, and did not work well on my 17.3" laptop. What I finally came up with that works great is getting a roll of tinted privacy window film from Home Depot and cut out a section to fit my exact screen dimensions. The result is fantastic as it filters out the rays causing eye strain, can be peeled on or off in seconds, and reused as many times as you like (it clings to the screen and doesn't need adhesives or hardware to work. I simply place it on the back of the screen where it clings until you need to use it again! The roll I bought was enough to cover two large windows, so would be enough for 25-35 laptop screens, and I think I paid $15 for the whole thing! Some friends of mine liked it so much they have it on their TV's that were too bright in their house, their car windows, and one guy used it to darken his prescription eyeglasses and loves it! Its so simple it borders on stupid, but I love it and will put it against the "Pet Rock" and Chia Pets" on QVC any day!
