Is Red Light Therapy Safe for Your Eyes? Here's What the Science Says
Red light therapy is generally safe for your eyes and, when used correctly, may offer surprising benefits—not just for vision, but also for appearance. Studies show that red light, particularly at specific wavelengths (such as 660 nm), can help support retinal health, reduce eye wrinkles, and improve visual functions like contrast sensitivity.
1. Helping People with Glaucoma and Retinal Conditions
Glaucoma affects over 80 million people worldwide and can slowly damage the optic nerve, often without early symptoms. Research suggests red light therapy can support eye health by energizing retinal cells and reducing inflammation. A study in Bioengineering highlights how red light may slow disease progression and protect vision by counteracting cellular stress and reducing swelling.
2. Smoothing Eye Wrinkles
As we age, fine lines around the eyes become common. A 2017 clinical trial by Chan Hee Nam et al. found that red light therapy significantly improved wrinkles after 12 weeks of consistent use, outperforming even white LED treatments in user satisfaction. It's a gentle, non-invasive option for skin rejuvenation.
3. Use with Care: Eye Safety Guidelines
While red light therapy is non-invasive, certain precautions should still be followed:
-
Wear protective goggles to shield your eyes during sessions.
-
Keep the device about 6 inches away from your face, and adjust based on comfort.
-
Remove contact lenses before treatment to avoid discomfort or reduced effectiveness.
-
Follow manufacturer instructions for safe and optimal results.
-
Consult your doctor if you have a history of eye conditions, surgeries, or take medications that increase light sensitivity.
Can You Just Close Your Eyes?
Closing your eyes helps, but specialized goggles provide better protection, especially if the device is very bright. When in doubt, consult a medical professional to ensure you're using the device safely.
