Hi all. In short, I had an eye test in October 2018. I was told to return within a few months to double check the prescription. I returned this weekend (different optician but the same company) and my prescription has changed significantly in terms of the astigmatism axes. I was under the impression that a few degrees of variation was normal. But this is much more.
I did go back to the most recent shop and the lady behind the counter told me “the values have hardly changed”, so not to worry. She would not double check my prescription.
Can anyone shed any light on whether the axes changes are realistic?
Right: +1 sph, -0.25 cyl, 85 axis
Left: +1 sph, -0.5 cyl, 110 axis
Right: +0.75 sph, -0.25 cyl, 5 axis
