Blue light, which is a high-energy visible (HEV) light with wavelengths between 380 and 500 nanometers, is emitted by various sources, including digital screens, LED lights, and the sun. While blue light is essential for regulating our circadian rhythm and boosting alertness during the day, excessive exposure, especially in the evening, can have several harmful effects on our health.

Blue light, or HEV light, is a color in the visible light spectrum that the human eye can see. As a short wavelength, it produces higher amounts of energy. The eyes cannot effectively filter blue light as opposed to other types of light, so it may pass through the eye to the retina.

In today's digital world, screens, artificial light, and the sun are unavoidable. But you can defend your eyes against excessive blue light exposure with Blokz® lenses. As essential as sunscreen is for your skin, Blokz® lenses protect your eyes and promote better sleep, empowering you to see, work, feel, and look your best.
