My eyes are getting sore from reading, and I have a lot of textbooks to read for school. Just wondering if there’s something to help with this? I’m thinking along the lines of some sort of plastic sheeth to place over the text that reverses the colours……but maybe that is an absurd request for magic. Would it be better to consider amber tinted glasses or something? I am reading under adequate lighting…… any help would be greatly appreciated! I did have lasik a few months ago, not sure if that’s making my eyes more tired than usual….
