| astigmatism |
Instead of the front surface of the eye being round it is more oblong. This prevents the light being focused in the right way and leads to blurring. Astigmatism can be secondary to the shape of the cornea or the lens, and is usually correctable with spectacle or contact lenses.

| asteroid hyalosis |
Benign condition in which flecks of calcium-rich fats become suspended in the eye's vitreous. The exact cause is unknown, but it may be due to aging collagen in the vitreous or decomposition of hyaluronic acid in the vitreous. Asteroid hyalosis typically is without symptoms, but some people experience blurred vision or floaters.

| astigmatism |
Condition in which the cornea's curvature is asymmetrical (the eye is shaped like a football or egg instead of a baseball); light rays are focused at two points on the retina rather than one, resulting in blurred vision. Additional symptoms include distorted vision, eyestrain, shadows on letters, squinting and double vision. Read more about astigmatism.
