Hello doctor i have a power of -0.50 in my left eye. i had a complete diluted eye checkup last year at this time. are reports were normal and my doctor didn't recommend me wearing glasses. Now since a week i feel a lot of strain in my eyes. they are red and itchy. my right eye is absolutely normal but my left eye is a little blurred. I have a alot of gadget use as well. should i start wearing glasses? or get my eyes checked and then try new prescription glasses. i also have dry eye problems
