What is blue light?
Blue Light is a part of the visible light spectrum, between 400nm and 500nm; making it one of the shortest, highest-energy wavelengths.
How you’re exposed to blue light
Our indoor lifestyle now revolves around digital devices and artificial lights, bathing us in blue light. Thanks to modern technology, it's easy to exceed healthy levels of blue light, especially at night.
The sun is the primary source of blue light you’re exposed to on a daily basis — that’s natural and even beneficial.
What is the impact?
Glare, eyestrain, headaches, sleep problems
Who is most at risk?
Children and Youth are especially at risk.
- No natural protection
- Tend to hold devices closer
- Larger pupils let in more blue light
- Average 9+ hours per day on a device
Also at risk:
How can you fully protect yourself?
It’s crucial to know what you’re buying when considering blue light protection:
- Completely clear lenses protect against UV and some short wavelength blue light, but leave you exposed to the peak wavelengths emitted by devices and artifical light.
- Blue-blocking glasses block ALL blue light — including healthy amounts, and distort your color perception.
- BluTech’s near-clear lenses filter more of the blue light known to be associated with glare, eyestrain, headaches and sleeplessness — without distorting the color you see.
Not a mere coating that can scratch or wear off, BluTech’s highly advanced lens is infused with proprietary pigments and dyes to mimic the way your eye naturally protects itself against blue light.

Is there good blue light?
Not at night. According to Harvard researchers, even dim light can interfere with a person’s circadian rhythm and melatonin secretion. “A level of brightness of about twice that of a night light has an effect”.
