A new study pubished in the journal Optometry & Vision Science found that heavy alcohol consumption significantly increased the risk of age-related cataract. There was some evidence, but not as strong, that moderate consumption may help prevent cataracts.
Cataracts require surgery to treat. The surgery is fairly common and usually results in a good outcome. However it is not without risks and bad outcomes like double vision and other problems can occur. It is best to avoid contracts altogether. Avoiding heavy drinking appears to be one way to do that.
