Do You Need Blue Glasses?

When facing electronic products

Harmful blue light with high energy can penetrate the lens and reach the retina, causing the atrophy and even death of retinal pigment epithelium cells. The death of photosensitive cells will lead to the loss of vision, which is irreversible. Blue light can also cause macular lesions. The lens in human eyes can absorb part of the blue light and gradually become turbid to form cataract. Most of the blue light will penetrate the lens, especially in children. So children need a pair of anti blue light glasses for kids more. The lens is clear and cannot effectively resist the blue light, which is more likely to cause macular disease and cataract. Many parents buy anti screen glasses for their children to use when they go to school.

Because of the short wavelength of blue light, the focus is not on the center of the retina, but on a point closer to the retina. Want to see clearly, eyeball is in tense state for a long time, cause eyestrain. Long time visual fatigue may lead to people's myopia deepening, diplopia, reading easy serial, attention can not concentrate and other symptoms, affect people's learning and work efficiency. Because of the blue light on the eye damage is particularly large, especially on the eye cells. Moreover, the anti blue rays of the eye to a large extent to reduce the harm of blue light on the eye, played a role in protecting the eye. Especially for people who need to use electronic products for a long time, anti blue light glasses can effectively inhibit the blue light emitted by the electronic screen, which can reduce the harm of blue light to human eyes.

When having sleep problems

Blue light can inhibit the secretion of melatonin. Melatonin is an important hormone that affects sleep. Its known role is to promote sleep and adjust jet lag. This can also explain why playing with a mobile phone or tablet computer without any anti blue light lenses before bedtime can lead to poor sleep quality and even difficulty falling asleep.

The benefits of blue glasses

Anti blue glasses mainly reflect harmful blue light by coating on the lens surface, or absorb harmful blue light by adding anti blue light factor into lens substrate, so as to realize the barrier of harmful blue light and protect eyes. The short wave blue light emitted by the display screen of electronic products can cause the decay of retinal pigment epithelium (RPE). Anti blue light glasses can effectively reduce the continuous damage of blue light to the eyes. Through the comparative detection of portable spectrum analyzer, the blue light intensity emitted by the mobile phone screen is effectively suppressed, and the harm of harmful blue light to eyes is reduced.

Anti blue light computer glasses are suitable for LED digital display devices such as TV, computer, pad and mobile phone. However, the anti blue glasses filter part of the blue light, and the picture will turn yellow when viewing objects. It is recommended to match two pairs of glasses, one pair of ordinary glasses for daily use, and one pair of anti blue lens glasses for LED display of digital products such as computers. Flat (no degree) blue ray eyeglasses are very popular with non myopia users, especially for computer office wear, and gradually become a fashion.
