BLUE LIGHT
PROTECTION

Avoid long-term eye damage.

Blue-violet light is everywhere, from your smartphone, tablet, computer and even from the sun. It can put your eyes at risk of long-term damage.

WHAT IS
BLUE LIGHT?

Light is made of electromagnetic waves that range in length and carry energy. Different colors are able to emit different amounts of energy. 
Blue light is often defined as visible light with wavelengths from 380 to 500nm. It is classified as Blue-Violet light (380 to 455nm) or Blue-Turquoise light (465 to 495nm).

WHERE DOES BLUE LIGHT
COME FROM?

IS BLUE LIGHT
BAD FOR YOUR EYES?

Blue light can be harmful to our eyes, but only in some conditions. Prolonged exposure to blue light can contribute to eye fatigue. In the long term, it may contribute to age-related vision loss.(1) One reason is blue light is more energetic. As such, Blue-Violet light is able to reach deep into the back of the eye and cumulatively affect the retina.(2)
However, not all blue light is bad or must be blocked. While Blue-Violet light may impact our retinas, Blue-Turquoise light can have a beneficial effect to our well-being. In the day, Blue-Turquoise light helps regulate our body’s natural sleep and wake cycles. It can also boost attention and memory, enhance reaction times, and elevate moods. Eye health relies on various factors, like age, genetics, and diet. Light is one of the modifiable risk factors on which an ophthalmic lens may act.
