If your eyes are causing pain. Go through these tips. Add your tips by downloading the slide and uploading it with your name. The idea is: my eyes were hurting me and I made these slides so that anyone can follow these tips, get some sort of help and spread these slides as a gesture of thanks.
I will try to make it a longer project. But I'd be delighted if you can do that.
