Top Eye Vitamins for Healthy Vision

Your eyes are more than just a means to see the world. They are vital to performing everyday functions such as moving, reading, and touching every aspect of your life, including socializing and protecting yourself from harm. Although most people assume it is just about this, the importance of eye health goes beyond vision! The health of your eyes is closely linked to overall health. Many eye conditions are related to other health issues, such as high blood pressure and diabetes. And as you age, maintaining healthy vision can help prevent falls and associated injuries such as fractures. In short, taking care of your eyes means caring for your entire body.

Maintaining healthy vision can be influenced by various factors such as age, environment, diet, and underlying health conditions. While these factors are crucial, incorporating specific nutrients into your diet may improve your vision and delay age-related eye conditions like macular degeneration. Research shows that taking certain nutrients contributes to better eye health.

There are several vitamins and nutrients that are important for maintaining eye health. Here are the top ones:

Vitamin A: Vitamin A is also known as retinol because it produces pigments in the retina, which help you see better in low light. It also nourishes the cornea, the clear outer layer in front of the eye. The cornea helps to focus light and helps in clear vision. Vitamin A deficiency leads to night blindness, eye dryness, and poor vision. Studies show that adequate vitamin A intake may be associated with a reduced risk of Age-related macular degeneration (AMD) and cataracts.

Vitamin C: Vitamin C is a water-soluble nutrient and a powerful antioxidant. It helps form collagen, a type of protein that helps provide structure to the eye. Vitamin C helps form the collagen structures for the corneal and scleral region  of the eye. As an antioxidant it fends off oxidation and protects the eye tissues.

Vitamin E: A diet rich in vitamin E is often recommended as part of maintaining healthy vision. Vitamin E is a fat-soluble nutrient and a powerful antioxidant. Since part of oxidative stress is considered one of the reasons for poor vision, cataracts, retinal degeneration, and other pathological conditions of the eye, consuming antioxidants like vitamin E may play a key role in mitigating oxidative stress and protecting delicate eye tissues. According to a randomized, placebo-controlled study (which is considered the gold standard), taking a daily dose of 400 international units (IU) of vitamin E, along with other nutrients such as carotenoids, zinc, and vitamin C, can help to slow down the progression of age-related macular degeneration (AMD) in older adults and prevent it from reaching advanced stages.

Lutein: Lutein is a carotenoid that is present throughout the central nervous system and brain. It is mainly concentrated in the peripheral retina, choroid (which supplies blood to and nourishes the entire eye), and ciliary body (the middle layer of the eyeball). A lesser concentration of lutein can also be found in the lens and iris of the eye. Due to its antioxidant and anti-inflammatory properties, lutein offers numerous benefits for maintaining good eye health.

Zeaxanthin: Zeaxanthin is another antioxidant carotenoid like lutein that is present in the eyes. The key role of zeaxanthin is to filter the harmful effects of natural and artificial lights. Zeaxanthin is stored in the macula, retina and fovea (a spot in the center of the retina). Fovea is responsible for all activities requiring intense visual details, such as driving and reading.

According to research conducted by the Schepens Eye Research Institute and Department of Ophthalmology at Harvard Medical School, the level of zeaxanthin in the retina strongly influences light damage. Researchers found that higher dietary levels of zeaxanthin provide significantly greater retinal protection than levels normally occurring in the diet. In essence, dietary zeaxanthin is shown to play an essential role in safeguarding the retina of the eye from the harmful effects of light.

Omega-3 fats: Omega – 3 fats are essential fats that form the structural components of all tissues and are vital for forming new cell membranes. Research shows that omega-3 fat, specifically DHA (Docosa hexaenoic acid) has directly influences the formation of rhodopsin. Rhodopsin is the most abundant protein in rod cells found in the retina. This visual pigment that is responsible for converting photons into chemical signals in the nervous system, which allows us to sense the light. DHA is necessary for converting the inactive form of rhodopsin to its active form. Preliminary studies  show that low levels of DHA can alter the content and function of rhodopsin.

Zinc: Zinc is a micromineral found in high concentrations in the eye, specifically the retina and choroid. Zinc interacts with taurine (amino acid) and Vitamin A to help regulate the light-rhodopsin reaction. Zinc is also an antioxidant that plays various roles in many biochemical reactions. Zinc performs this subtle biochemical reaction which may influence the development and progression of several chronic eye diseases.

Pro DHA Eye by Nordic Naturals: Pro DHA Eye is a powerful formula that protects against harmful ultraviolet blue light and supports eye health.
