I just recently start college after being out of school for 5 years. After the first week of school I started noticing that after reading for a long period of time I would get really bad headaches behind my eyes, after a week my eye's were all blood shot and I was have problems focusing on words close up. I took a couple days off of reading my headaches went away and I could focus my eye's on words close up again. I went to see for an eye exam and was perscribed bifocials, Primarily for reading and looking at the black board. I got my glasses yesterday. When I wear my glasses my eyes seem to burn like their dry. I am still getting my headaches, usually when I take my glasses off and have to readjust my eyes. Also when I put my glasses on sometimes and read small words the words are a little blurry. Is this because I periodically use my glasses through out the day or is it that my script is wrong?
