How does blue light damage the eyes?

When light enters the eye, the cornea, lens and retina will absorb blue light. It is still unclear whether other eye tissues such as conjunctiva will absorb blue light. Research has focused on the effects of blue light on the retina, causing changes in the patient’s macula. Recommended reading: Zeiss anti-blue lenses give your eyes better care

1. The three types of blue light products can instantly blind the eyes, and the damage is irreversible.

2. One-year-old children have the largest pupils. The damage rate of products containing blue light to the macula through the eyeball is 100%, and the pupils of two-year-old children become smaller, and the damage rate of products containing blue light to the macula through the eyeball is 70%-80%. Children from the age of six have smaller pupils, and the damage rate of products containing blue light to the macula through the eyeball is 60%-70%. For people over 60 years old, the damage rate of blue-ray products that damage the macula through the eyeball is 20%.

If your child is still young, please keep him away from Blu-ray products.

What about the damage caused?

1. Video terminal syndrome and other changes caused by close contact with blue light. People who use a lot of screen workers, mobile phones and computers need to wear anti-blue lenses. Nowadays, there are many glasses with anti-blue light.

2. At present, there are some foods or drugs to help prevent blue light from affecting the ocular surface or retina.

Some experts even screamed that after three to five years, blindness will explode in large areas!

The most important eye disease is cataract. A major source of cataract is high-frequency blue light radiation. Because sunlight also contains this high-frequency blue light similar to ultraviolet rays. Because of the blue light in the sun, people usually only reach old age. Cataracts, but now cataracts are getting younger and younger, the main reason is that they are over-reliant on mobile phones and electronic products.

There are currently 5 million cataract patients in China, and it is increasing at an annual rate of 10%!

Staring at the mobile phone for five or six hours a day is equivalent to letting the blue light radiated by the sun's rays to our eyes in a lifetime be absorbed by our eyes in a few years.

The World Health Organization's WHO Eye-loving Association issued a report in 2008, when blue light radiation caused 30,000 people worldwide to lose sight every year. The association also issued an orange warning at the end of 2009: "The potential threat of blue light radiation to humans will far exceed the destructive effects of Sudan red, melamine, SARS, and HINI, and it will invisibly devour human eyes."

Some time ago, at a symposium on “concerning children’s vision protection starting from blue light” held in Shanghai, there was a data showing that among children aged 0-6 in my country, 66.6% have been exposed to electronics since the age of 4. For the product, it takes 1.5-2 hours to play on a tablet or mobile phone every day. The ophthalmologists at the symposium also emphasized that the damage of high-frequency blue light to the eyes is irreversible, and as a result, one can only wait for blindness.

At the same time, scientists also found that the degree of blue light's damage to the eyes also varies with age, ranging from 80-90% for 6-19 years old, 60-70% for 20-39 years old, and 50% for 40-60 years old. Li Junping, a clinical ophthalmologist at the University of Virginia in the United States, said that the damage of high-energy blue light is a chain reaction, which first causes the death of light-sensitive cells, and then causes macular degeneration of the retina, which then leads to a gradual decline in vision and then complete blindness.

The visual cells and visual cells in the human body are more sensitive to blue light, and high-intensity blue light can cause damage to the visual cells. For older people, the crystals will get older and turn yellow. Even yellow can neutralize part of the blue light. Children, sensitive to strong blue light, can cause damage to visual cells, affect vision, reduce vision, and even develop eye diseases.

So, from now on, let us take it seriously, for our children, for our next generation, we must first be conscious.
