Product Description

Blue light hazards 1.Structural damage: harmful blue light has extremely high energy, which can penetrate the lens to reach the retina, leading to atrophy of retinal photoreceptor cells, resulting in vision loss or even complete loss of vision. Blue light can also cause macular degeneration. The lens in human eyes will absorb part of the blue light and gradually become cloudy to form cataracts. Most of the blue light will penetrate the lens, especially for children who cannot effectively resist blue light, which is more likely to cause macular degeneration and cataracts. 2.Visual fatigue: due to the short wavelength of blue light, the focus does not fall in the center of the retina. See clearly, the eyes will be in a state of long-term tension, resulting in visual fatigue. Long-term visual fatigue may lead to deepening myopia diplopia, easy to serialize when reading, inattention and other symptoms. 3.Poor sleep: blue light can inhibit the secretion of melatonin, which is an important hormone that affects sleep. The current known role is to promote sleep and regulate jet lag. This can also explain why playing with cell phones or tablets before bedtime can lead to poor sleep quality and even difficulty in falling asleep. 4.Causes glare: Due to the relatively high energy of short-wave light, the high scattering rate when it encounters small particles in the air is the main cause of glare. Patients with retinopathy and eye surgery (excimer surgery, cataract surgery) are very sensitive to light and experience abnormal glare, which is also caused by short-wave blue light. Why not block all blue light? Blue light is not all harmful blue light. What is really harmful is blue light with wavelengths between 400 and 450 nm, while blue light between 480 and 500 nm has the effect of regulating biorhythms. Sleep, mood, memory, etc. are all related to it. On the contrary, it is beneficial. Select Size Please measure your monitor and compare with our size chart before ordering to ensure the right size.
