“About Astigmatism and Glasses”
I recently bought my first glasses ever for a -4.1 astigmatism prescription (which I believe it is the vertical type). Something that I notice when I wear them is that the image shrinks vertically, an example is when i'm looking at my phone I can tell it looks less rectangular and more square-ish
It this normal? Are the glasses okay? Have I been seeing everything stretched all this time without realizing it?

Interesting question, astigmatism is irregular shape of the cornea on the front of the eye. Most people describe it as being more shaped like the side of a foot instead of symmetrically round like a basketball. Astigmatism, especially larger amounts of astigmatism can distort the shape of an image. Without seeing your glasses and checking your eyes I can not say whether the image without the glasses or with the glasses is the distorted image. The easiest way to find out is find something that is a perfect square(measure with a measuring tape) and then look at it with and without the glasses.
