The amount of blue-enriched light needed to reduce melatonin levels in this study did not exceed safety standards for the eyes and did not cause immediate harm to eye tissue.

Short‐wavelength enrichment of polychromatic light enhances human melatonin suppression potency

Randomized Controlled Trial

Human

2015 Apr

The researchers used blue-enriched lights to help people sleep better and checked if those lights could hurt eyes — they didn’t. So, the lights are safe at the levels used.

Similar Assertions

Higher levels of broad-spectrum light reaching the eye are linked to greater reductions in nighttime melatonin levels in healthy adults, with more light leading to more suppression.

Light that contains more blue wavelengths can reduce melatonin production at lower brightness levels than light with less blue, meaning it has a stronger biological effect for the same amount of light energy.

Exposure to artificial light at night reduces the body's production of melatonin, a hormone involved in sleep regulation, and the more light a person is exposed to, the more melatonin is suppressed, regardless of the light source.

In healthy young guys, better-quality daylight-like LED lights don’t seem to change daily melatonin levels or brain performance like focus and memory — so upgrading light quality might not always boost health or thinking skills.
