Review on OPTHOPATCH Kids Eye Patches Hypoallergenic Vision Care by Inocencio Anas

I've read some reviews that say they don't stick or are too stiff and I'm wondering what kind of patches they use? My son has to wear the patch 4 hours a day and I always had a hard time keeping it on my face but this patch was great! He doesn't seem to notice it at all, and when he rubs his eye it doesn't loosen at all or curl around the edges. It's soft and flexible and doesn't even bother me when I take it off. He has very sensitive skin, but it doesn't leave any marks. I bought these because they were better than the Ortopad and now I'm so happy I did for so many reasons!
