¿Por qué hay que suplementar los ojos con luteína y zeaxantina?
What is lutein?
Lutein is the most important nutrient in the human retina. It is found in the macula and lens of the retina of the eye, especially in the macula which contains a high concentration of lutein.
Lutein and zeaxanthin are indispensable nutrients in the human retina, distributed in the inner and outer ring of the macular region. Studies have shown that lutein and zeaxanthin can effectively resist blue light and protect the macular health of the retina.
Zeaxanthin and lutein constitute a strong blue protection barrier in the retina of the human eye, which weakens and absorbs blue light in advance and effectively avoids the potential damage of blue light to visual receptors. At the same time, with their excellent antioxidant, anti-inflammatory and blue light filtering properties, as well as their unique molecular structure, these two substances also protect brain health, prevent cognitive decline, and provide solid protection for our wisdom light.
The ratio of lutein to zeaxanthin is 5:1, which is consistent with the ratio of retinal pigment in the human body, and is known as the ideal nutrient ratio.
This matching mimics nutrient intake in the body’s natural state, helping the two work together to optimize vision and cognitive function while enhancing macular pigment density.
The role of zeaxantina and lutein benefits
luteína vitamina Protect the retina and enhance vision
lutein zeaxanthin is a good antioxidant that can avoid oxidative damage to the retina when it absorbs light, protect the optic nerve blood vessels, maintain good blood circulation, reduce color difference, and improve vision.
lutein for eyes Filter blue light to slow eye aging
Blue light can penetrate the eye and damage the retina and macular area, especially the fat outer layer of the macular area is vulnerable to light damage, so this area is prone to degradation, and lutein can form a protective film to filter out blue light and avoid harmful rays from sunlight. Lutein can relieve visual fatigue, dryness, blurring, photophobia and other symptoms
lutein supplement Prevent glaucoma, cataracts and other eye diseases
Lutein can reduce the oxidation intensity of ocular protein, and the higher the intake, the lower the incidence of glaucoma; At the same time, lutein is also the only carotenoid that exists in the eye lens, which can improve the lens resistance and delay or prevent the occurrence of cataracts. Reduce the probability of macular degeneration and disease, macular disease is the main cause of blindness in the elderly, lutein can help elderly patients with degenerative macular disease improve vision.
lutein foods Prevent high myopia and fundus lesions
High myopia is easy to cause retinal detachment, water and other fundus lesions, and can even lead to permanent blindness. Supplementing enough lutein can improve eye resistance and reduce the incidence of lesions.
When is lutein needed?
People who use electronic devices for a long time, people who use eyes with high intensity
Frequent eye rubbing, blinking, amblyopia, strabismus children
Dry eyes, serious red blood contact lens wearers
Glaucoma, presbyopia, myopia, cataract patients with eye diseases
When to take lutein?
Lutein is a fat soluble type, taken after breakfast and lunch, the best absorption effect. Does not irritate the intestines of sensitive people.
Do not take lutein at night, especially before going to bed, the absorption effect is poor, the liver burden is heavy!
Studies have shown that consuming 10 mg of lutein per day can significantly reduce eye strain caused by prolonged computer use.
Can lutein be eaten for a long time?
Lutein needs to persist and eat for a long time to have a role! Because lutein is not effective as soon as you eat, it takes a time to accumulate in order to gradually act on the eye macula. According to the White Paper on Chinese Eye Nutrition and Health, it is recommended to maintain it for at least 6 months to have a significant and stable effect. If consumed in excess at a single time, it may damage the liver, make the skin yellow, and can not achieve the absorption effect.
Is lutein an IQ tax?
No, it’s not! Lutein is a natural antioxidant, mainly in the retina, macula, is an indispensable nutrition for the human body, because people in the face of light, lutein will continue to be exhausted, if consumed, the eye will be damaged by blue light, eye tissue aging, nutrition eye health, so lutein in the eye plays a vital role.
Lutein can not be synthesized by the human body itself, but can only be supplemented by most of human lutein from vegetables and fruits, including a variety of dark green vegetables, orange vegetables , fruits and grains, such as amaranth, spinach, pumpkin , carrot , mango , orange , corn , kiwi and so on. Although the food contains lutein, but the diet is difficult to absorb the daily amount required, so it is recommended to supplement from dietary supplements!
