Trying to understand astigmatism a little better.
From my understanding the horizontal blur with letters is related to astigmatism?
Which can also be caused from “correcting” astigmatism that is not actually there?
Asking because with my current lens “correction” that does have cylinder values, I have notice that if I am looking at a sentence while wearing my lenses and I move my head up or down, the result is that at only a certain degree point there is vertical blurring. HOWEVER, when I am not wearing lenses the vertical blur is constant.
So does real astigmatism visually change what you’re looking at constantly or only on the degree at which the astigmatism occurs?
I know my current “correction” is not correct and I am trying to figure out if what I am noticing is lens induced astigmatism or general myopic blur.
