I first got headaches in the month of July and when it happened everyday I got my eyes checked. I found out I had weak eye muscles, and got prescribed for glasses. - 0.75 in each eye. The headaches disappeared for 2 weeks only to return again. I consulted my eye doc and he told me take painkillers thrice a day. I changed my doctor after that but he also told me that I had the same power and my headache could probably be caused by weak eye muscles. The headache still didn't go. Then I went to a new optometrist and got my eyes checked again. This time he prescribed me a power of -0.75 in left eye and -1 in right with a lil bit of cylindrical power. The headaches disappeared for about 2 weeks. But it's been 2-3 days now and I feel a slight headache these days. I have been working a lot on my laptop and my eyes started watering when a went to watch a 2.5 hr movie at the theatre. What's causing this? Help please I'm a student and I can barely concentrate on my work with these incessant headaches!
