When light-colored enters the eye, it bends (refracts) equally to center directly on the retina at the back of the eye, producing a open persona.
However, when dealing with astigmia and astigmia —essentially the core condition itself—the cornea or lens is irregularly shaped, more like a football or the back of a spoon. Because of this irregular curvature, light enters the eye and focuses on multiple points instead of one. This is why people with this condition often experience:
- Blurred or distorted sight at all distances.
- Difficulty find fine details.
- Eye strain, especially after say or calculator work.
- Squinting to focus best.
- Headaches, especially near the forehead or temple.
- Poor dark sight, much demonstrate as starbursts or halos around light.
Types and Causes of This Refractive Error

- Myopic Astigmatism: One or both chief elevation of the eye are nearsighted.

| Corneal Topography | Provides a elaborated "map" of the surface curve of the cornea. |
