Astigmatism occurs when either the cornea or the lens of the eye has a slightly different surface curvature in one direction than the other. Instead of being even and smooth in all directions, the surface may be flatter or steeper in some areas.

Slight amounts of astigmatism usually don't affect vision and don't require treatment. However, some people with astigmatism seem to have significant difficulty driving at night or working under certain light conditions.

If you have astigmatism, take a look at the following helpful tips.

The Ocular Nutrition Society (ONS) issued the following statement regarding the urgent need to educate Americans about the role of nutrition in supporting eye health:

Significant scientific evidence exists to support the role of certain nutrients, including zinc, vitamins C and E, lutein, zeaxanthin and long-chain omega-3 fatty acids, to help promote health in the aging eye. The displacement of nutrient-dense foods by processed foods in the Western, or American, diet is disconcerting, as is the lack of awareness of key nutrients and other modifiable risk factors that impact eye health. The lack of key diet-derived nutrients is a modifiable risk factor for protecting eye health, and eating a healthy diet rich in these nutrients is encouraged.

The National Eye Institute estimates that over the next 30 years, the number of Americans that experience eye health issues will double because of aging baby boomers. The demand for vision care service is expected to flood the healthcare system by 2015 due to age-related eye disease and the diabetes epidemic.
