I was using this ageless sleep mask to help prevent age lines around my eyes, but discovered that it also has healing properties. I have macular degeneration. I have been getting shots in the eye to slow down the degeneration for over a year. After wearing this mask every night for 6 weeks, my doctor said there wasn't as much fluid behind my macula and I was reading farther down the eye chart, so he sent me home without a shot! I am seeing clearer and my glasses are too strong now. My shots cost the insurance company $2000 each, I can't tell you the value of this mask!
