This irregular curvature causes mild rays getting into the attention to focus at a number of factors relatively than a single level on the retina. This scattering of sunshine leads to distorted, blurry imaginative and prescient in any respect distances. Consider it like wanting by means of a warped lens – the picture is stretched and out of focus.
Forms of Astigmatism: Completely different Paths to Blurred Imaginative and prescient
Astigmatism isn’t a one-size-fits-all situation. It manifests in a number of completely different kinds, categorized primarily based on the place the visible distortion happens:
Myopic Astigmatism
