1. High-energy short-wave blue light penetrates the cornea and lens to the bottom of the retina, directly causing irreversible chemical damage to the retinal nerve of the eye, and directly or indirectly causing damage to cells in the macular area.
2. Blue light can lead to fundus injury after cataract surgery
The body's own lens turns yellowish as we age, which helps filter out blue light and prevent it from damaging us. However, after cataract surgery, when patients lose these natural barriers, the "lens", the blue light will go directly to the retina, which will damage the retinal pigment epithelium cells, seriously affecting the health of the fundus.
3. Blue light can cause blurred vision, resulting in Visual fatigue and VDT (Visual Display Terminals) syndrome
After the blue light is focused into the fundus, it falls between the retina and the lens but not on the retina, which will aggravate the color difference and visual blur degree. When the eye muscle is excessively tense, the eye blood supply is excessively tense, and the eye blood supply is strengthened, thus aggravating fatigue.
4. Blue light can inhibit the secretion of melatonin, disrupt the balance of hormone secretion, affect the quality of sleep, and improve the incidence of major diseases.
