Blue Light (aka High Energy Visible HEV) light is used in today’s devices. Blue light has a shorter wavelength than other lights in the visible spectrum, causing it to scatter more and decrease in contract. This in turn causes tension in the eyes as they are constantly refocusing. Whilst blue light is aimed to reduce eye irritation during the day, when exposed to at the evening time, especially after a full day of exposure, it causes havoc for our eye and hormonal health.
Firstly, Melatonin, otherwise known as the sleep hormone, hates it! Blue light affects the hormone’s natural release, which is why some people have trouble getting to sleep, or have a poor quality of sleep after being on a device and why it is strongly recommended you go offline two hours before bed time.
Empire + Co have used this knowledge to craft blue light blocking glasses that look good.
