Protecting your eyes starts with proper nutrition. Vitamin A is among the most essential nutrients to keep the eyes protected and your vision sharp.

How the Eye Ages
As we get older, there are changes in our eyes that impact how well we see. Microscopic tears, cataracts and glaucoma can all develop, causing changes in vision and even vision loss. You may also experience chronic dry eyes as well as macular degeneration, which makes the vision less sharp and and worse in changing light conditions, like the nighttime.

Nutrition plays a big role in the health of your eyes, and vitamin A is at the center of it. Making sure you get enough of it can mean better vision for the long term.

Vitamin A’s Benefits for Eye Health
Vitamin A is a fat-soluble vitamin the body needs on a daily basis for proper function. When it comes to your eyes, vitamin A protects the cells of the eye as well as the various parts of the eye, making sure they function properly and adjust to changes in light. This is crucial for moving around, and of course driving, in the dark. Vitamin A is also an antioxidant that protects the tissues of the body by preventing the damage of free radicals, which can hurt the cells of the body.

Proper Vitamin A Intake
For adult women, 700 mcg (2,300 IU) of vitamin A is recommended on a daily basis, and 900 mcg (3,000 IU)  for adult men. In addition to vision problems, a weakened immune system is a common symptom of vitamin A deficiency, as vitamin A also helps keep the body's natural defenses strong.

You can first and foremost get vitamin A form food sources. Eggs, meat and fish oil are naturally rich in vitamin A, as well as vegetables like dark leafy greens, cantaloupe and carrots. Try to work them into your daily diet as often as possible and you should get what you need no problem.

The next step is to take a supplement. Vitamin A is typically included in all multivitamins -- just look for one with the recommended daily dosage, unless you’ve been instructed to take more by your doctor. Vitamin A supplements are sold on their own for this purpose. Your doctor can determine if you're in need of additional vitamin A through a blood test.

Women who are pregnant or breastfeeding will need to discuss vitamin A with their doctor -- too strong a dosage of vitamin A can negatively impact the health of a fetus, with the potential to cause birth defects.
