What is Blue Light?
Blue light on the visible light spectrum is shorter in wavelength (380 - 500 nanometers), having the highest energy of all visible light. It’s found in sunlight and necessary for keeping us energized and awake, also regulating our circadian rhythm. The issue arises though when blue light comes from artificial sources in large unwanted quantities.
What does blue light do to your eyes?
Digital devices that emit the highest amounts of blue light can be on your laptop, computer, smartphone, or eReader like a kindle, exposing the delicate tissues of the eyes. Blue light reaches deep into the back of the eye (further than UV rays), which over time can cause damage to the retina — an important part of the eye that enables vision. The naked eye’s cornea and lens are unable to block this harmful light, which is where blue light glasses become very convenient.
Why does small specs use filter blue light lenses?
On average, we spend “as much as 12 hours a day in front of TVs and computers,” according to Forbes. With the dramatic increase in digital media usage, it’s important more than ever to protect your eyes. Our lenses block a good number of blue light. They have a clear tint, so you can wear them regularly.
