Very good application on the child's eye, it sticks easily and remains stable for houuurrrs (even after crying! tested! :P) and it comes off even easier, without leaving those annoying glues... I find it difficult to find but it's worth it! I haven't been satisfied with any other similar product...

I initially used 3M Opticlude for my child who has amblyopia, but later switched to Master Aid and I am very satisfied. They are much cheaper (25% or even more, depending on where you buy them), and I would say they are of higher quality (soft texture, easy to remove, nice designs that children like).

We initially tried a different brand, but ended up here because the others irritated the area around the eye too much. These patches are very good. They have a fabric-like texture that doesn't irritate and doesn't leave any glue residue. I did a little trick of sticking and unsticking them a couple of times on my freshly washed hands to remove excess glue, so that it wouldn't be difficult to remove later on. This way, it didn't cause any "waxing" effect. They also have a light dark film inside to block light, which other brands don't have. Very good and at a good price. I recommend them!
