If you have to work out what helps eyestrain on your own-- look for the colored plastic strips given to kids with reading (tracking and focus) issues. There's blue, red, and I think both yellow and green, and ONE will work noticeably better for you than the others. The kids store the strip like a bookmark, and when reading it's like one of those pocket magnifiers my dad used to use. That will give you an idea of which TINT to use-- Going to someone who has treated vision processing disorders really helped. $10 for the set of bookmarks, and testing them out over several days, was very, very helpful in the long run.
