Add a non-glare coating to your lenses to help astigmatism. Non-glare lenses can help reduce the amount of light entering your eye, helping people with astigmatism see better at night.

Early on, you may be able to reduce the effects with glasses. Use sunglasses to lessen glare. Surgery is the common, effective way to treat more vision-impairing cataracts. During the surgery, the eye doctor removes your cloudy lens and usually replaces it with an artificial lens.
