Risks of Blue Light
We already know that too much ultraviolet light (UV) is harmful to the eye and skin. There is now a lot of research that shows a specific wavelength of blue light causes a number of problems as well. This high energy blue light is a major risk for cataracts and macular degeneration. It is one of the major components of glare and effects sleep/wakefulness patterns.
Blue light will not be as dangerous as UV light but it still needs to be addressed. Everyone is in danger but in particular children, because most children are looking at LED digital devices all day, whether it is social media, school work or computer gaming.
Blue light plays an important role in people’s sleep patterns. Too much exposure to blue light inhibits the release of melatonin which signals to the brain that it is night time and therefore time to sleep. For example a person working on a brightly lit computer screen or interacting with their iPhone or iPad late at night, may find sleep is harder to come by.
This information has led to the design of a new coating on the lens that reduces blue light exposure, eliminates UV and greatly enhances comfort. We are now using this coating known as Prevencia for a large range of people including students and many adults.
