Blue light protection from digital devices

Blue light protection from digital devices

You have probably heard about blue light and how it can effect us, especially our sleeping patterns. Blue-violet light is everywhere. It is produced by the sun as well from many digital devices and fluorescent light sources. Blue light is a shorter wavelength than visible light and tends to scatter more, making it harder to focus. When using a computer or digital device, the blue light released creates unfocused noise that reduces contrast and can contribute to fatigue and eye strain. We have found many patients benefit from a blue light filter such as the Essilor Crizal Prevencia lens. Unlike traditional multicoated lenses which absorb UV rays and reduce reflections, the Prevencia lens blocks a specific range of blue-violet light. If you are suffering from digital eyestrain, make an appointment for a comprehensive examination and we can demonstrate the lens technology.
