Can anti-blue glasses prevent myopia?

With the increasingly prominent problems of visual fatigue and myopia caused by electronic products, anti-blue glasses have gradually become the new darling of the glasses industry.

Especially after elementary and middle school students start to learn through online classes, the anti-blue glasses are even more propaganda to "prevent myopia."

When many parents saw the slogan, they only considered how to protect their children's eyesight without in-depth understanding, so they hurriedly placed orders.

So the anti-blue light glasses that sell for more than ten yuan to several hundred yuan really have such a function?

It is understood that blue light usually refers to visible light with a wavelength of 400-500 nanometers, which is widely present in nature, electronic screens and sunlight.

Experts said in an interview with the media that the so-called anti-blue light products to prevent myopia lack scientific basis. If they are not purchased properly, they will cause damage to the eyes.

It is reported that the blue light hazard is related to the dose of blue light received by the retina, and only under long-term, high-intensity irradiation, blue light may cause damage to the retina.

At the same time, the medical community believes that the main damage of blue light to human eyes may be fundus macular degeneration rather than myopia, and there is no direct evidence that blue light can cause myopia.

It is good protection for the eyes to cultivate the correct habit of using and protecting the eyes.
