According to the researchers, it only takes a few minutes of daily light exposure to experience positive effects.

Most studies involving vision and light revolve around blue light and its potential negative impact on cells in the retina, leading to vision loss over time.

This new study, which comes from University College London and was recently published in Journals of Gerontology, instead focuses on red light and its potential therapeutic effects on aging vision.

Based on existing past studies that involved various animal models like mice, the new research tested the effects of this light on human eyes.
