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.
