Among your five senses, sight is by far the most important one. Your eyes need the same vitamins and minerals as the rest of your body, but there are a handful that are especially important.
According to Healthline, these nutrients help keep your eyes healthy, shield them from damaging light, and prevent age-related degenerative diseases.
Your likelihood of developing an eye disorder increases with age. The most common types of eye disease include cataracts, macular degeneration, glaucoma, and diabetic retinopathy. Factors such as age, heredity, chronic conditions, and personal decisions all have a role in determining an individual's susceptibility to certain diseases.
One of the most common reasons people go blind is because they don't get enough vitamin A. The light-sensitive cells in your eyes, called photoreceptors, cannot function properly without this vitamin.
If you don't get enough vitamin A in your diet, you could end up with night blindness, dry eyes, or even more serious conditions.
Vitamin A can only be found in food that comes from animals. The highest dietary concentrations are found in beef liver, egg yolks, and dairy products. The antioxidant provitamin A carotenoids found in many fruits and vegetables are also a good source of vitamin A.
Lutein and Zeaxanthin
For example, the macular pigments lutein and zeaxanthin are yellow carotenoid antioxidants. The macula, the central region of the retina, the layer of light-sensitive cells on the back wall of the eye, is where you'll find the greatest concentration of these cells.
Natural sun protection can be found in lutein and zeaxanthin. A primary purpose of these accessories is to protect your eyes from potentially harmful blue light.
The amount of lutein and zeaxanthin in your retina is directly related to how much you consume, according to controlled research. Many foods contain both lutein and zeaxanthin. Spinach and green peas are two of the most well accepted examples.
There is also speculation that egg yolks, sweet corn, and red grapes contain notable amounts of lutein and zeaxanthin.
Omega-3 Fatty Acids
The omega-3 fatty acids EPA and DHA play an important role in maintaining healthy eyes. DHA is highly concentrated in your retina, where it may help with eye health. The maturation of the mind and sight is a crucial process that must occur during childhood. Therefore, a lack of DHA might cause eye problems, especially in children.
Research suggests that patients with dry eye diseases may benefit from taking omega-3 supplements. It has been suggested that omega-3 fatty acids can help protect against a number of eye conditions.
The best food source of EPA and DHA is oily fish. There are also a lot of omega-3 supplements you can buy, and they can be manufactured from fish or microalgae.
The eyes have the highest antioxidant needs of any other organ in the body. Although there is a lack of rigorous study on the topic, the antioxidant vitamin C seems to be especially important for maintaining healthy eyes.
Vitamin C concentration in the aqueous humour of the eye is the highest of any body fluid. Aqueous humour refers to the fluid that makes up the clear, outer layer of your eye.
The amount of vitamin C in the aqueous humor is directly related to the amount of food eaten. Thus, supplementing with vitamin C or eating foods high in vitamin C will help you focus better.
Cataract patients have a low antioxidant level, according to observational studies. Vitamin C supplement users also had a lower chance of acquiring cataracts, as shown by these studies.
High quantities of vitamin C can be found in bell peppers, citrus fruits, and guavas, among many other fruits and vegetables.
Vitamin E is an anti-oxidant that helps keep fats from becoming rancid. The retina contains many fatty acids, thus getting enough vitamin E is crucial for healthy eyes.
Extreme deficiency of vitamin E can lead to retinal degeneration and blindness, but whether or not taking a supplement is helpful if adequate intake has been achieved by food alone is unclear.
Some of the best places to get your vitamin E fix are from almonds, sunflower seeds, and vegetable oils like flaxseed oil.
You have an abundance of zinc in your retinas. Zinc is a component of many vital enzymes, including the antioxidant superoxide dismutase.
As an added bonus, it's supposed to contribute to the formation of retinal pigments necessary for vision. Night blindness may develop as a result of zinc deficiency. Zinc can be found naturally in oysters, pumpkin seeds, and peanuts.
