If you've ever been fitted for glasses, you may recall your doctor talking about vitamin A. Good eyesight and strong night vision is more likely among those with a healthy amount of vitamin A intake [source: OFDS].
You can get a good dose of vitamin A by eating animal liver and eggs or by drinking milk from cows. Beta-carotene-rich vegetables will also supply you with what you need. Examples include carrots, apricots, spinach and cabbage.
Supplementation works well as the body has a high tolerance for vitamin A and overdoses are rare. Men with vision problems may find it especially useful to help maintain their eyesight in the years to come.
