Blue-violet 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-violet light as opposed to other types of light. It is also around us with the sun being the biggest source of blue light.

That's why blue-violet light filtering lenses suit modern lifestyles; because they filter blue-violet light from the sun (the biggest source of blue-violet light) and indoors from ambient light through windows and from artificial sources.

These lenses help reduce visual discomfort caused by prolonged exposure to screens, such as computers, smartphones, and tablets. By minimizing the intensity of blue-violet light that reaches the eyes, they can also contribute to better sleep quality, as excessive exposure to this light—especially in the evening—can disrupt the body’s natural circadian rhythm.

In addition to comfort, blue-violet light filtering lenses may help protect the eyes from long-term damage. Studies suggest that overexposure to high-energy visible (HEV) light, particularly in the blue-violet range, may contribute to retinal stress and age-related macular degeneration.

Whether you're working remotely, spending hours on digital devices, or simply navigating environments filled with artificial lighting, these lenses offer a practical and protective solution. They’re designed not only to enhance visual clarity but also to support long-term eye health in a world where digital exposure is constant.
