Red light therapy appears to be at least temporarily beneficial in several eye conditions, especially as the result of its anti-inflammatory and wound-healing effect. Preliminary research demonstrated that red light therapy could alleviate symptoms such as dry eyes, age-related macular degeneration (AMD) and diabetic retinopathy by stimulating cell regeneration and reducing inflammation. Other studies indicated that red light therapy might improve eye health generally because it promotes blood flow to the retina and mitochondrial function in eye cells. However, further research must unravel the mechanisms that trigger these processes and quantify their effectiveness of red light therapy on eyes.

The eyes can be subjected to red light at varying frequencies, depending on needs and specific conditions.

To ensure safety and effectiveness, this must be done as part of such a regimen as will be advised upon in a consultation with a healthcare professional.

It has created great promise for treating specific ocular diseases, more so in retinal health. This, again, is not a standalone treatment but one that will form part of an inter-menial approach toward treatment. This is a promising treatment that requires much greater diversity in terms of clinical trials in the treatment of a broad range of ocular conditions to determine their real efficacy and safety. Always consult an eye specialist before embarking on any new course of treatment.
