Blue Light Screen Protector Laptop 15.6 Inch, PYS Blue Light Filter for Laptop, Enhanced Anti Blue Light and Anti Glare, To Protect Your Eyes
[DAMAGE TO 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 will lead to vision loss or even complete loss, which is irreversible.- The lens of the human eye absorbs some blue light and becomes cloudy gradually, forming cataracts. Most of the blue light penetrates the lens, especially in children, whose crystal lenses are relatively clear and cannot effectively resist blue light, which is more likely to lead to macular lesions and cataracts.[VISUAL FATIGUE] Due to the short wavelength of blue light, the focal point does not fall at the center of the retina, but at a position further in front of the retina.- If you want to see clearly, your eyes will be in a tense state for a long time, causing visual fatigue. Long- term visual fatigue may lead to deepened myopia, diplopia, serial reading, inability to concentrate and other symptoms, affecting people's learning and work efficiency.[POOR SLEEP] Blue light inhibits the production of melatonin, an important hormone that affects sleep and is known to promote sleep and regulate jet lag.- This also explains why playing with a phone or tablet before going to bed causes poor sleep quality and even difficulty falling asleep.
