Red light therapy (RLT) is gaining attention for its potential to support eye health. It uses low-level red light, often around 630–670nm, which may help improve retinal function, reduce eye strain, and slow age-related vision decline.
Benefits of Red Light Therapy for Eyes
-
Supports retinal health
Studies show red light may help protect and repair aging cells in the retina. -
Reduces eye fatigue
Especially helpful for people who use screens for long periods. -
May improve visual clarity
Some users report better sharpness and contrast after regular use.
How to Use It Safely
-
Use red light with correct wavelength
Choose devices around 630–670nm — these are gentle and safe for short exposure. -
Use in short sessions
Start with 1–3 minutes per day, ideally in the morning. -
Keep a safe distance
Hold the light about 15–20 cm (6–8 inches) from your eyes. Do not stare directly at the light unless the product is designed for eye use. -
Keep eyes closed or semi-closed
Most research recommends keeping eyes closed during treatment to avoid discomfort.
Important Notes
-
Only use medical-grade or research-backed devices.
-
Do not use infrared (above 800nm) directly on eyes — it penetrates too deeply.
-
If you have an eye condition, consult your doctor before starting.
Conclusion
Red light therapy can be a helpful, non-invasive way to care for your eyes. With short, regular sessions and the right device, you may experience better comfort and visual health over time.
