Red light therapy (RLT) is showing promise as a natural way to support eye health and improve vision, especially as we age. It uses safe, low-level red light—usually around 670nm—to help boost energy production in the eye cells.
How Red Light Therapy May Help Vision
-
Supports retinal health
Red light may protect the retina by improving mitochondrial function in eye cells. -
May slow age-related vision loss
Studies suggest red light can help older adults maintain sharper vision. -
Reduces eye fatigue
Regular use may ease digital eye strain caused by screens.
How to Use Red Light Therapy for Eyes
-
Use a device with wavelengths around 670nm.
-
Shine the light toward closed eyes for 1–3 minutes per day, ideally in the morning.
-
Be consistent—benefits usually show after a few weeks.
Safety Tips
-
Never shine infrared light (above 800nm) directly into your eyes.
-
Use only trusted devices made for eye-safe use.
-
Consult your doctor if you have eye diseases or recent eye surgery.
Conclusion
Red light therapy is a gentle, non-invasive method that may help maintain vision and support eye health as you age. With the right light and routine, it could be a helpful addition to your eye care routine.
