Eye protection method:
Blue light and astigmatism are two main causes of discomfort to human eyes, among which blue light (especially short-wave blue light, above 470nm) is more harmful to human eyes, and people's intraocular pressure increases and stings; The other is astigmatism, which directly leads to dryness and fatigue. LED lights and electronic products have the greatest influence. Due to the large dispersion, the lens of the human eye needs to be fine-tuned constantly, resulting in a lot of movement, which leads to insufficient supply of aqueous humor and dryness. If this happens for a long time, the lens will lose its elasticity and become nearsighted. If you or your family have elevated intraocular pressure and tingling, it is recommended to replace the lamps or screens at home to prevent blue.
