Hello, I have mild myopia and astigmatism. My old glasses prescription from 4 years ago (that was unchanged two years ago) was:
Left: -1.25 sph, -0.75 cy, 162.5 degrees
Right: -1.25 sph, -0.75 cy, 25 degrees.
The old glasses have a base curve of ~4.5 and pupillary distance of 60.
I have sunglasses of the same prescription with a pd of 59. Both pairs are comfortable to wear.
I went for a sight test elsewhere recently and after a bodged first attempt (left eye -1.75, 0.25, 170 that gave me crippling headaches) the new prescription was given as
Left: -1.25, -0.75, 10
Right: -1.25, -0.75, 10
The pd in the new glasses is 62 and the base curve is 4.
Frames are almost identical in size and shape.
Vision through each eye is sharp from the new glasses however despite wearing them for a week I had depth perception and distortion problems, specifically the centre of my vision felt too close to me so everything looks flat, I got mild headaches and had the sensation that my eyes were looking in different places...as if I was crossing them or one was looking wide of true. When I took them off I felt like I was looking at a magic eye picture, depth perception and orientation without glasses was upset for over a day after stopping wearing them.
The store says the test was done carefully and glasses are within tolerance, so any ideas why I am unable to cope with the change in glasses?
