Red light therapy for eyesight

Red light therapy has shown promising potential in supporting eye health, particularly in offsetting age-related macular degeneration. Research by Glen Jeffrey at University College London suggests that exposure to flashing red light in the morning can enhance mitochondrial function in the photoreceptors of the eye, potentially helping to maintain vision in individuals over 40. This effect is attributed to improved mitochondrial activity and reduced reactive oxygen species in the cells 1 2.

Andrew Huberman highlights the importance of safe usage, emphasizing that red light should be viewed early in the day for only a couple of minutes, and the light intensity should not be so bright as to cause discomfort. It's crucial not to force the eyes open if they naturally want to blink or close in response to light, ensuring the safety and health of the eyes in the process 1 3.

While red light therapy appears promising, Dr. Huberman advises consulting with an eye care professional before starting any such therapy to ensure it is appropriate for individual health needs 1.
