Talk:Astigmatism

Old talk

perhaps start out saying what it actually is. It says what causes it, but not what it actually is. I guess is something like the acuity depends on the angle of what you're looking it. So vertical lines might appear clearer than horizontal lines. (Wish I knew, I'm new here !) Divenal (talk)

@Divenal: That's how I wanted to tackle it, but I could find no way to do so simply, as it manifests differently in different people. I thought the little illustration in Jake's video showed well enough how the 'scattered' light hits the retina at different places causing distorted or multiple images.. Please go ahead and start off with what you come up with as to what it is.Hannie (talk) 14:34, 31 May 2020 (UTC)

Spherical equivalent

Spherical equivalent direct to this article. Maybe a section about it. Viceroy Sam (talk) 12:32, 16 March 2021 (UTC)
