In this age of laptops, mobile phones and social media, we need to ensure we’re protecting our eyes and our friends at Oscar Wylee have us covered.
What is blue light?
Blue light regulates the circadian rhythm.
Although its focus is at 460 nanometers, blue light’s wavelengths fall
between 380-495 nanometers. Because of this, it is also known to be the High Energy Visible (HEV) light. It is most commonly found in sunlight and is necessary for energizing us as well as regulating our circadian rhythms.
Blue light is more harmful than UV.
Blue light penetrates to the back of the eye, triggering nerves that causes discomfort and eye strain – leading to permanent damage to the eye. Our eyes’ natural filters do not provide sufficient protection against blue light rays from the sun, let alone the blue light emanating from digital devices.
Smartphones emit the most blue light.
In our technology-driven world, LED and LCD digital screens mean we are exposed to more blue light than ever before. Smartphones emit the
highest levels of blue light compared to other devices. Because we hold them so close to our face, the exposure is maximized and the risk of developing retinal damage is very real.
A direct connection to the brain.
Unlike rods and cones, these retinal ganglion cells (pRGCs) in the eye have no relationship to vision. Instead, they connect to the suprachiasmatic nucleus, which is responsible for regulating the body’s circadian rhythm. These cells, activated by blue light, are one of the main reasons that
scientists believe there is a connection between blue light and our circadian rhythms.
