While the coloring was great on the hazel and blue lenses I received, the quality left much to be desired. They are not well fitting, flimsy, and quick to flip inside-out during application. Even with the help of my girlfriend and the applicator, it took over an hour to get both lenses in my eyes. My eyes were red, itchy, and dry. When compared to my prescription lenses, the TTDeye lenses were thin and did not hold a circular shape. Do not recommend and find it hard to believe that these are FDA approved. I would beware of ulcers or scratching if you order these.
