Blue Light Filter Lenses
Where does Blue light come from?
Blue light is defined as a range of the visible light spectrum, which has a wavelength size between 400−495nm.
Now, some light wavelengths are different sizes to others. Blue light is known to have a shorter wavelength, which means that blue light is classed as what we call 'high-energy visible light'
Blue light sources are becoming increasingly common in today's environment. Exposure to blue light comes from a variety of technologies including computers, televisions, and lights. Much of the exposure arises from light emitting diodes (LEDs) as well.
More and more, people are exposed to blue light via everyday technology. The majority of people in the UK & Europe own a tablet, phone or laptop. These are all sources of Blue light which most of us come into contact with daily.

What does Blue Light do to the eyes?
Harvard Medical School which conducted experiments, studies and research into this area found that blue light exposure can negatively impact the eyes and sleep patterns in particular. It found that blue light may have affected melatonin levels during experiments and thereby disturbed sleep patterns. You can find out the exact details on their findings here: ''Blue light has a dark side''
More studies after the Harvard experiment went into this subject and they also found blue light to be detrimental to eye health and sleep patterns in particular.
There has been some debate over this topic over the last few years by some academic groups who believe blue light has no negative health effects on the eyes from day-to-day exposure. A lot of the same academics also believe that more research into this field is still required before universally agreeing on the detrimental effects of exposure to blue light, found in all the studies to date.
