With the improvement of living standards, more and more people are concerned about eye health, and various eye care products seem to be on the rise overnight. Blue glasses have become one of the popular eye protection products, and many nearsighted people go to optical shops to wear blue glasses. But is it necessary to prevent blue light from myopic lenses?

In fact, myopia lenses do not have to be equipped with anti-blue light!

Since the anti-blue glasses are designed for the blue light emitted by electronic products on the screen, the blue light has a wavelength of 430nm-480nm, short wavelength, strong energy, and irreversible damage to the eyes.

As for the harm of blue light, as early as 1966, a study by the German scholar Neil discovered that blue light can cause damage to retinal cells, resulting in decreased vision or even loss of vision. At the 2010 International Optical Association Annual Meeting, people in the optics industry pointed out that short-wave blue light has extremely high energy and can directly contact the retina through the lens. Blue light irradiates the retina to produce free radicals. These free radicals can cause the decline of retinal pigment epithelial cells. The decline of epithelial cells can lead to the lack of nutrients for photosensitive cells and cause vision damage. The harm of Blu-ray might as well!

But the anti-blue glasses actually only need to be worn when using electronic products. Because the blue light of the electronic product screen directly enters our eyes, the light emitted by the Lord has very strong energy, and there is no need to wear it at other times.

The wearing of myopia glasses with anti-blue light effect is not only an electronic product, but also means wearing myopia glasses. Under normal circumstances, this is not advisable, because when we are not in contact with electronic products, whether it is indoor or outdoor light will produce faint blue light, because these light will enter our eyes through reflection, in the process of shuttle, The energy will be reduced, not enough to harm our eyes.

Wearing anti-blue light myopia glasses at this time is prone to visual chromatic aberration when looking at things, and the eyes are uncomfortable for a long time, which may cause other adverse symptoms.

So my conclusion is that myopia lenses do not need to be anti-blue light! If you want to prevent blue light, you can buy a pair of blue light glasses. If wearing two pairs of glasses is too troublesome, it is recommended that my myopic friends buy anti-blue glasses, which can protect their eyes and are easy to take off. As for anti-blue light myopia lenses, don't buy them.

What the eye protector wants to say is that blue glasses can filter blue light to protect your eyes, but you should pay attention to eye hygiene in daily life. As a result, good eye hygiene is a good way to prevent myopia.
