How does blue light affect your eyes? Blue light penetrates deep into the back of the eye (further than UV light) and over time the cornea and lens of the naked eye cannot block this harmful light, which can cause damage to the retina That's why blue light-blocking glasses have become so important, and why blue-light blocking glasses are worn. What is Blu-ray? Blue light in the visible spectrum has very short wavelengths (380-500 nanometers) and has the highest energy of all visible light. It can be found in sunlight and is necessary to keep us alive and awake, and it also regulates our circadian rhythms. Problems arise, however, when large amounts of blue light come from artificial light sources. In addition, the popularity of electronics with screens and energy-efficient lighting increases the likelihood of exposure to blue wavelengths, especially after sunset. Prolonged exposure to blue light can cause digital eye strain. Wear our glasses and your eyes won't get tired. Reduce eye strain and sensitivity to light when facing digital screens. For office workers or anyone who has to look at a screen all day, this is just the right choice.
