Red Light Therapy and Your Eyes: Safe or Dangerous?
I get asked about eye safety constantly. People want to know if they need goggles, if they can treat their face without protection, and whether red light can damage their vision. These are all fair questions.
The Short Answer
Red light therapy at normal treatment distances and durations is generally considered safe for your eyes. Some research even suggests certain wavelengths may support eye health. But there are nuances worth understanding.
Why Red Light Differs from Other Light
Lasers are dangerous because they concentrate enormous energy into a tiny point. LED-based red light therapy panels spread light across a large area, dramatically reducing intensity at any single point.
Eyes Open or Closed?
For Facial Treatments
Most people close their eyes naturally. This is fine and probably the most comfortable approach. The light will still penetrate your eyelids and reach the tissues around your eyes.
For Body Treatments
If you're treating your whole body and facing the panel, you don't need to stare at it. Just look away or close your eyes periodically. No special goggles required for most home devices.
When to Use Eye Protection
- High-powered professional devices: Follow manufacturer instructions
- Very close treatment distances (< 6 inches)
- If you have light sensitivity conditions
- If taking photosensitizing medications
- Post-eye surgery (consult your doctor)
Red Light for Eye Health
Interestingly, some studies suggest that specific red light wavelengths (around 670nm) may actually support retinal health and visual function. Research is ongoing, but the preliminary findings are promising for age-related vision concerns.
