What should you know about red light therapy for eyes?

Skin around the eyes is thin and easily irritated, while the eye itself is sensitive to bright light. Devices intended for facial skin may not be designed for direct eye exposure. Red light is not a general treatment for blurred vision, redness, floaters, pain or a diagnosed eye disease. The cause of an eye complaint determines whether an optometrist or ophthalmologist is needed.

Use only a device with explicit eye-safety instructions for the intended area, and never stare into LEDs. Keep treatment away from the eye if the manufacturer says so, remove contact lenses when instructed, and stop for discomfort, headache, after-images or skin irritation. Check with an eye professional first if you have an eye condition, recent eye procedure or use light-sensitive medicine.

Seek urgent eye care for sudden vision loss, severe pain, a curtain-like shadow, new neurological symptoms, marked swelling or chemical exposure. Arrange an examination for persistent redness, discharge, light sensitivity, flashes, floaters or recurrent headaches. These symptoms need diagnosis, not a trial of a cosmetic light device.

Ask whether red light is suitable for your symptoms, medicines and skin or eye history, what device safeguards apply, and what improvement would be realistic.
