I am selling this item because my child's amblyopia treatment has ended. Since we mostly used a different eye patch, I don't think it has been used much. ● This is an eye patch made in England for amblyopia and strabismus training. Developed jointly by an ophthalmologist and a patch maker in England. Easy to put on and not too big, so it's not likely to get in the way. ● The temples of the glasses are passed through the holes, and another hole is hooked onto the nose pads to secure it. Also, for types without nose pads, it can be fixed to the glasses with rubber. ● For both left and right eyes. ● This eye patch is made of soft, cushioned, and breathable fabric. This makes it gentle on the skin and comfortable to wear. The fabric used for the eye patch is certified by Oeko-Tex®, is soft, and is hypoallergenic. Multiple layers of breathable fabric are layered, and the inner black layer is made of 100% cotton. This provides good comfort for the skin, absorbing and wicking away moisture. For these reasons, this eye patch provides a comfortable and skin-friendly wearing experience.
