How harmful the blue light of electronic products to the eyes?

Blue light exists in a large amount of our daily life, such as computer monitors, mobile phones, digital products, etc. The blue light in these wavelengths will increase the number of toxins in the macular area of the eye, which seriously threatens our eye health.

What damage does blue light do to us?

Easily damaged eye structure

Harmful blue light has extremely high energy and can penetrate the lens directly to the retina, causing the atrophy or even death of retinal pigment epithelial cells. The death of light-sensitive cells can lead to decreased vision or even complete loss of vision.

Blue light can also cause macular degeneration. The lens in the human eye absorbs part of the blue light and gradually becomes cloudy to form a cataract, while most of the blue light penetrates the lens, causing macular degeneration and cataracts in the eye.

Prone to visual fatigue

Due to the short wavelength of blue light, the focal point is not located in the center of the retina, but further forward from the retina. Therefore, the eyes should be in a tense state for a long time, which can easily cause visual fatigue. Long-term visual fatigue may lead to symptoms such as deepening of myopia, diplopia, and inability to concentrate, affecting people's learning and work efficiency.

Prone to insomnia

Blue light can inhibit the secretion of melatonin, which is an important hormone that affects sleep. It is currently known to promote sleep and regulate jet lag. This can also explain why playing on mobile phones or tablets before going to bed can cause poor sleep quality or even difficulty falling asleep.

Protect your glasses with blue light-blocking glasses

Use blue light-blocking glasses to filter out the interference of scattered short light waves emitted by the mobile phone screen, so that the lutein in the macular area of the retina is not damaged by blue light, so it has the effect of protecting the retina.

Anti-blue light glasses are suitable for wearing when using LED digital display devices such as TVs, computers, PADs and mobile phones, but it is not recommended to wear anti-blue light glasses for a long time in daily life, because anti-blue light glasses filter some blue light, and the picture will be yellowish when viewing objects. , It is recommended to use two pairs of glasses, one pair of ordinary glasses for daily use, and one pair of anti-blue light glasses to use when using LED display digital products such as computers. Flat light (no degree) anti-blue light glasses are very popular among non-myopia users. They are specially worn for computer office work, and have gradually become a fashion.
