Can lutein protect the eyes?
The Chao News reporter interviewed relevant medical professionals.
"Lutein is not a medicine, it is a food grade additive and a health product," said Zhang Su, a chief pharmacist at Zhejiang Provincial People's Hospital. Lutein is an antioxidant that helps delay and improve eye aging, while protecting the macula from damage caused by blue light and ultraviolet light. After supplementing with lutein, the density of retinal pigment in the macula will increase, so it has a certain effect on preventing and improving age-related macular degeneration and preventing cataracts. "However, lutein itself is also present in some vegetables and fruits, such as carrots and oranges, and is also consumed in daily diet."
So what are the hazards of long-term use of lutein?
Zhang Su introduced that in the 2013 edition of "Reference Dietary Nutrient Intake for Chinese Residents", a daily intake of 10 milligrams of lutein is beneficial for physical health. It is recommended that the maximum daily intake should not exceed 40 milligrams. "This refers to the total intake of lutein, including the content in food."
Zhang Su explained that lutein is a fat soluble supplement, and serum lutein mainly reflects recent intake, while lutein concentrations in adipose tissue and liver reflect long-term intake. The liver and spleen are the main storage organs. But because it is not a drug, there are few literature reports on safety or adverse reactions. "Previously, a foreign study mentioned that after taking lutein continuously for 8 years, a small amount of pigment crystals appeared on the retina, but it did not affect vision, and the crystals gradually disappeared on the retina after stopping taking lutein."
In fact, many lutein products are advertised to prevent myopia, so many parents will purchase related products for their children.

"In outpatient clinics, many parents come back and ask: 'Do you want to give your child lutein? Or can lutein prevent myopia?' Deputy Chief Physician Yu Jie from the Ophthalmology Center of Zhejiang Provincial People's Hospital said, 'We won't prescribe lutein to prevent myopia because it's not a medicine. I will tell parents that lutein does not have a direct scientific basis for preventing myopia. If you want to take it, you need to judge the product yourself and at least don't have any problems eating it.'"
Every summer vacation, there are a lot of children who come to see their eyesight, and because they spend a long time at home using their eyes up close, it is also a "small peak" for children's myopia.
In Yu Jie's view, the "gold standard" for preventing myopia in teenagers is to cultivate good behavioral habits: outdoor for 2 hours every day; Follow the 20-20-20 rule for close range eye use. After 20 minutes of close range eye use, we need to look at a distance of 20 feet for at least 20 seconds. Of course, the longer the rest time, the better; Please remember when using electronic products: larger screens, clearer, and farther away are better than smaller screens and closer distances.
"We also suggest parents to supplement their children with more fresh fruits and vegetables, but this is mainly to help them maintain a balanced diet and nutrition," said Yu Jie.
