Blue Light 101:
Benefits & Side Effects

Benefits

Blue-turquoise light (380-500nm) makes up roughly one-third of visible light. When your eyes receive blue light during the day you experience a boost in alertness, brain function and feel energized.

It regulates the circadian rhythm and is super important for your health and well being. However, the benefit is in the timing and excessive blue light should be avoided during the evening.

Eye Strain

The compounding effects of blue light over time, specifically between 380nm and 450nm, is harmful and damaging to retinal cells because your eyes cannot filter out light very well.

Excessive blue light emitted from phones and computer screens can be irritating for many people, causing eye strain at the end of the day, and suppressing the secretion of melatonin at night making it hard to fall asleep.

Blue Light Lenses

Blue light lenses have an anti-reflective (AR) coating that cuts down on glare and reduces the amount of blue light that passes through your lenses. This can reduce sleep disruption, neck pain, and tired eyes.

Blue light AR also helps with night time driving because modern headlights are higher in the blue light spectrum – filtering out blue light cuts down on light halos and allows you to have more comfortable vision in these situations.

Benefits

Eye Strain

Your eyes can’t filter out visible light very well and excessive blue light from phones and computer screens can damage the retinal cells, cause eye strain, and difficulty sleeping.
