Hi, I just got glasses and whenever I take them of I get a migraine on the left side of my head. I can see clearly without glasses, but I have had a few optic migraines in the past so my eye doctor wanted me to get some. He said I only need to wear them for watching tv, driving, computer etc, but I can t seem to take them off without get a headache a minute later. The prescription for my glasses are, Right: Sphere -0.25 Cylinder -0.50 Axis 160 Left: Sphere -0.50 Cylinder -0.50 Axis 012 . My eye doctor also said I have an astigmatism, if that has anything to do with it. Thanks!
