I am currently normalising my astigmatism. Currently at -1.00 dioptre of astigmatism in both eyes and now normalising to -0.50.
I noticed that when I look up towards the top edges of my glasses, it seems as if everything is clearer and that I feel as if I’m in a ‘stronger’ astigmatic prescription. But when I look through the middle of my lens, that’s where I can see the directional blur and clear it up.
Is this because of the quality of the lens (they’re really cheap) so the astigmatism is not even in all places? Or is it that you just have a sharper focus when your eyes point more upwards? Or is it just a natural curvature of all lenses?
