How Do Eye Vitamins Work?
There may be no easier way to care for your eyes than by adding an eye vitamin into your daily routine. After all, a good eye vitamin contains all of the proper vitamins and nutrients your eyes need to stay lubricated, make minor repairs, and keep your vision sharp.
But how do eye vitamins work? What do they do once they’re in your body, and why are they so good for you? In this article, we attempt to answer just those questions, plus break down all of the nutrients an eye vitamin should contain. Let’s get to it!
What Vitamins Are Good For Eyes?
The purpose of taking a daily eye vitamin is to ensure your body is getting all of the most eye-healthy nutrients. As you choose an eye vitamin, make sure it contains some or all of the following:
Lutein and Zeaxanthin
These two carotenoid antioxidants are vital to proper eye health. Absorbed by the retina, lutein and zeaxanthin act as a natural sunblock for your eyes, and have been found to greatly decrease the risk of developing age-related macular degeneration (AMD).
Vitamins A, C, and E
A powerful antioxidant and immunity booster, Vitamin A has been found to reduce the risk of developing AMD and cataracts. Vitamin C helps your eyes form their structure, while Vitamin E protects your eyes from harmful free radicals that can cause serious damage.
Vitamins B6, B9, and B12
Ensuring your diet contains one or more of these B vitamins is an important part of proper eye care. Most notably, vitamins B6, B9, and B12 are responsible for lowering levels of homocysteine, an amino acid that can lead to dangerous inflammation..
Omega-3 Fatty Acids
Omega-3 fatty acids, sometimes known as “fish oil,” are perhaps best known for being good for your brain, but they also help keep your eyeballs lubricated and prevent dry eye and vision loss.
Zinc
In addition to helping to form the pigment of the retina, zinc helps to prevent issues like blurred vision.
How Do Eye Vitamins Work?
Though it may sound counterintuitive, like anything else you ingest by mouth, eye vitamins go straight to your stomach. From there, they can be categorized in one of two ways: water soluble, or fat soluble. Water-Soluble vitamins are absorbed by the intestines before they are carried through the blood to wherever it is they are needed, in this case to the eyes.
However, water-soluble vitamins are easily flushed out of the body via sweating and urination, and therefore should be put into the body on a more frequent basis. Daily eye supplements make this necessary replenishment a simple task. Important, eye-healthy vitamins that are water soluble include:
- Vitamin C
- Vitamin B
- Saffron
On the other hand, fat-soluble vitamins tend to remain in the body longer because they are harder to break down. Unlike water-soluble vitamins, which make it to the bloodstream pretty quickly, fat-soluble vitamins are absorbed by lacteals in the small intestine, then transported throughout the lymphatic system before finally releasing into the blood. Once in the bloodstream, they are transported throughout the body. Important, eye-healthy vitamins that are fat soluble include:
- Lutein and zeaxanthin
- Vitamin A
- Vitamin E
- Copper
- Zinc

A good eye vitamin will include nutrients such as lutein and zeaxanthin, zinc, and vitamins A, C, and E, among others.
