Longer wavelengths in sunlight pass through the human body and have a systemic impact which improves vision
In a small study, researchers found that infrared wavelengths in sunlight, and from an 850 nm LED panel, can penetrate the human body. These wavelengths appeared to improve color contrast sensitivity, a measure of visual function. However, the study's small sample size and the unclear real-world significance of the vision improvements limit the strength of these findings.
