When it comes to maintaining eye health, nutrition plays a key role, particularly in today’s modern and often screen-focused world. But which supplements are good for eye health? From lutein to omega-3s, this article looks into the best supplements for eye health, exploring how these nutrients support your sight and contribute to overall ocular health.

Lutein and Zeaxanthin

Lutein and Zeaxanthin are two antioxidants found in high concentrations in the macula, which is the part of the retina responsible for clear central vision. These carotenoids are often referred to as the best supplements for eye health because they act as natural sunblock for the eyes, helping to filter out harmful blue light and ultraviolet rays. Regular intake of lutein and zeaxanthin through diet or supplements could help to maintain macular health, and potentially slow the progression of age-related macular degeneration.1 Foods rich in these nutrients include leafy greens, egg yolks, butternut squash and pumpkin, but for those who struggle to consume enough through diet alone, supplements can be a convenient alternative.

Vitamin A

Another common nutrient which arises when discussing which supplements are good for eye health is vitamin A, which is essential for the production of rhodopsin, a protein in the eyes that allows you to see in low light conditions. Vitamin A can also help to support the health of the cornea, which is the eye's protective outer layer. Vitamin A can be found in foods including carrots, sweet potatoes, and eggs, but supplementing with it could help you meet your daily requirements of this vital nutrient.

Omega-3 Fatty Acids

Omega-3 fatty acids, in particular EPA and DHA found in fish oil, have been shown to support eye health, for example helping support symptoms of dry eye syndrome. These fatty acids help maintain the integrity of the tear film that protects the eye's surface and also support retinal health and development. Many of us in the Western world do not consume enough oily fish in our diets, so omega-3 supplements can be a useful way of providing these essential fats that are crucial for maintaining moisture and preventing inflammation in the eyes.


Antioxidants play an important role in combating oxidative stress, a factor that can contribute to cataracts and other age-related eye issues. Vitamins C and E, along with the mineral zinc, are powerful antioxidants that can support eye health. These nutrients help to regenerate other antioxidants and protect the eyes from damage caused by free radicals. A balanced diet can provide these antioxidants, but eating a perfect diet is not always possible, so it’s worth bearing in mind that supplements can help to ensure adequate intake for those concerned about their eye health.

Looking after your eyes means considering which supplements are good for eye health, and incorporating them into your daily routine. Lutein, vitamin A, omega-3s, and a broad spectrum of antioxidants are among the best supplements for eye health, each playing a unique role in supporting different aspects of vision and ocular function. It’s useful to note that a proactive approach to eye health through nutrition and supplementation, could help keep your vision and eyes healthy as you age.
