What is blue light?
Each day your eyes are exposed to a spectrum of visible and invisible light rays that can have a range of effects.
Most people are aware that sunlight contains ultraviolet light rays that can tan or burn our skin. To protect our eyes from these rays sunglasses provide UV400 protection.
Blue light rays are the portion of the visible light spectrum with the shortest wavelengths and highest energy, not simply the blue colour we see. Blue light is naturally emitted from the sun but it is also emitted from man made digital devices such as computers, phones and televisions.
The intensity digital devices emit blue light and the amount of time people spend using these devices and the proximity of these screens to user's face have opticians and health care professionals concerned about possible long-term effect of blue light on eye health. The human eye cannot effectively stop blue light from reaching the retina.
Blue light is well documented to boost alertness and cognitive function which contributes to difficulty sleeping. Too much blue light late at night from your phone or laptop could be causing sleepless nights and daytime fatigue. Blue light has also been shown to contribute to digital eye strain.
A convenient way to reduce your blue light exposure is to use a blue light filter. Our glasses have a thin protective coating that blocks blue light from reaching your eyes.
