Blue Ray Cut glasses
The Blue Light Rays
Blue light is a particular electromagnetic radiation of the visible spectrum, with a short wavelength, between 430 nanometers and 475 nanometers.
30% of people use digital devices for about 6 hours a day, around 14% for 10 hours. Most light sources emit blue light, including Smartphones, Tablet, incandescent lamps, fluorescent lamps, LCDs and LEDs, found in ambient lighting systems and digital devices such as PC monitors, TV monitors.
Blue light damage
Scientific research has highlighted a relationship of the effects of blue light on the eye. Studies highlight the induction of an oxidative stress of corneal epithelial cells when irradiated by blue light. The consequence of this is constituted by the alteration of the ocular surface, responsible for symptoms such as dry eyes, heaviness, itching and sting) already present in subjects exposed to the use of video terminals for more than 6/8 hours a day using lenses of poor optical quality and without protective filters (the so-called video terminal stress syndrome). A possible interference with metabolism after exposure to blue radiation was also highlighted. Furthermore, other studies have hypothesized an interference on the sleep cycle in subjects exposed to blue light.
How to protect us from blue light
It is advisable to use high quality lenses, which have a filter with the ability to “shield” the eye from blue radiation. Shinoox® reading glasses are now available with the latest generation of Digilenses® lenses which incorporate a photopigment which, when irradiated by light, is activated by creating a protective layer that only blocks blue radiation, preventing it from interacting with the eye structures.
