It is said that lutein is the eye gold, can it really protect the eyes?

Date:Mar 31, 2021

Nowadays, we have more and more contact with computers and mobile phones, online shopping, chatting, and playing games. However, facing computers and mobile phones for a long time has caused serious damage to the eyes.

Therefore, many people who pay attention to health will look for some effective eye-care and eye-care dietary methods. Eating more foods or health products containing lutein has become the first choice for eye protection, and some people even call lutein the "eye gold". So, can lutein really protect eyesight?

Everyone knows that after the human eye receives light, it can only form a clear image when it falls on the retina. The central part of the retina is the macular area, which is extremely sensitive in processing light and color, and the most core nutrient that supports the normal operation of the macular area is lutein.

Lutein can form a protective film, filter out blue light, and prevent the fat outer layer of the macula from degenerating due to light damage, affecting vision. At the same time, lutein is also an antioxidant, which can prevent the retina from oxidative damage when it absorbs light.

What are the specific effects of lutein on the eyes?

Protect the retina and enhance vision

Lutein is a good antioxidant, which can prevent the retina from oxidative damage when it absorbs light, protect the optic nerve and blood vessel, maintain good blood circulation, reduce chromatic aberration, and improve vision.

Filter blue light, delay eye aging

Blue light can penetrate the eyeball and damage the retina and macular area, especially the fat outer layer of the macular area is easily damaged by light, so this area is prone to degeneration. Lutein can form a protective film to filter out blue light and prevent harmful rays from sunlight from invading the eyes. .

Lutein can relieve the symptoms of visual fatigue, dryness, blur, and photophobia

Prevention of fundus pathology

High myopia is prone to cause fundus diseases such as retinal detachment and water accumulation, and can even lead to permanent blindness. Supplement enough lutein to increase the resistance of the eyes and reduce the incidence of lesions.

Prevent eye diseases such as glaucoma and cataracts

Lutein can reduce the oxidation intensity of ocular globulin. The greater the intake, the lower the incidence of glaucoma. At the same time, lutein is the only carotenoid that exists in the eye lens, which can increase the resistance of the lens and delay or prevent the occurrence of cataracts. .

Reduce the probability of macular degeneration and disease

Macular degeneration is the main cause of blindness in the elderly. Lutein can help patients with age-related degenerative macular disease improve their vision.

However, it is worth noting that as the amount of eye use increases, the lutein content in the eyes will continue to be consumed, but the human body cannot synthesize this element autonomously. Once the lutein content is low or depleted, it will be harmful to the eyes. It was a disaster. Therefore, in addition to reasonable eye control, people need to constantly replenish lutein to enhance eye resistance.
