It's exactly what I needed it to be
My 5 year old needed to patch her good eye for several hours a day to correct her bad eye.  We had an eye patch already at home which didn't work well with the glasses being over it.  I found this product and it's perfect.  It fits nice and snug on her glasses and achieves what we needed it to.  I may buy another as a backup.  Great product
