With the popularization and development of electronic products, we are increasingly in contact with computers and mobile phones, chatting and playing games However, long-term exposure to computers and mobile phones has caused serious damage to the eyes. Therefore, many people will find some effective ways to nourish and protect their eyes. Eating more food or health products containing lutein has become the first choice for most people, and some people even regard lutein as “eye gold.”. So, can lutein really protect eyesight?
As we all know, after receiving light, the human eye can only form a clear image when it lands on the retina. The central part of the retina is the macular region, which is extremely sensitive to the processing of light and color, and the core nutrient that supports the normal operation of the macular region is lutein.
What is lutein?
Lutein is an important nutrient in the macular region of the retina. In the human body, it is concentrated in the macula of the human eye, which is located in the center of the retina and is the most sensitive area for vision. The cone cells responsible for vision and color perception are distributed in this area.
The role of lutein
- Antioxidants, which can remove free radicals from light damage.
- Absorbing harmful blue light from life can help the retina stay below ultraviolet rays.
- Reduce the risk of blindness in patients with macular disease, especially dry age-related macular degeneration.
- Reducing the damage of computer radiation to the eyes can reduce symptoms such as visual fatigue.
- Delaying the occurrence of cataracts.
- Prevent the sequelae of high myopia, such as retinal detachment, hydrops, flying mosquitoes, etc.
- Lutein has a good therapeutic effect on amblyopia, and can play a certain role in treating or alleviating myopia, but it can only be used as an auxiliary means.
