Oct 26, 2021

Many families now attach great importance to the protection of eye health. lutein and beta carotene are widely known, which one is more suitable for oneself? What is the difference between lutein and beta carotene?


What are the benefits of lutein for eyes?

eye anatomy

1. Lutein is yellow, mainly concentrated in the macular area of the retina of the human eye. It is an important pigment component on the retina. Lack of it can cause blindness.

2. Protect the eyes from ultraviolet rays and blue light, reduce the formation of free radicals, prevent damage and degradation of the macular area, delay aging and prevent eye disease.

3. Lutein can promote the regeneration of rhodopsin in retinal cells, can alleviate the damage of vision when light and dark are interlaced, and can prevent moderate myopia and retinal detachment.

4. Lutein can also alleviate the symptoms of asthenopia, such as blurred vision, dry eyes, pain, swelling and pain, and photophobia.

5. Lutein also has the effect of promoting eye development, can increase the pigment density of the macula and enhance the resistance of the macula.

6. Lutein can also prevent macular disease, such as macular degeneration or retinitis pigmentosa and other symptoms. It can also prevent the formation of drusen.

These foods contain lutein:

Lutein is generally found in yellow and green vegetables.

Such as: marigold, spinach, broccoli, water spinach, egg yolk, kiwi, corn, mango, kale, fungus, leeks, lettuce, etc.

What are the benefits of beta carotene for eyes?

1. Beta carotene can increase the humidity of the eyes, help keep the cornea moist, make the eyes transparent and clear, and promote eye health.

2. Beta carotene can be converted into vitamin A in the body, which is a component of retinal cells, can promote the regeneration of rhodopsin, and has the effect of enhancing eyesight.

3. Beta carotene can prevent cataracts, protect the fiber part of the eye lens, and prevent damage to the lens.

4. Vitamin A can prevent night blindness and strengthen the ability of the eyes to distinguish colors.


These foods contain beta carotene:

Foods rich in beta carotene are generally orange, yellow, and red foods.

Such as: soybean, carrot, tomato, persimmon, pumpkin, spinach, mango, cantaloupe, apricot, melon, loquat, etc.

Lutein and beta carotene have different nutritional parts

Lutein is mainly distributed in the macular area of the retina and the lens, which can filter out the blue light in the sunlight and prevent the blue light from harming the eyes. If blue light enters the eyes, a large amount of free radicals will be produced, causing cataracts or degeneration of the macular area. Therefore, once lutein lacks, presbyopia, cataracts, asthenopia, pseudomyopia and other diseases will occur.

Beta carotene is the precursor of vitamin A and is currently the safest product for vitamin A supplementation. For the eyes, β-carotene mainly acts on the ocular mucosa and rhodopsin. Insufficiency can cause dry eyes, decreased dark adaptability, and night blindness.
