This listing is for a leather eyepatch for adults. If you would like children`s sizes please ask.  This is for the dark brown colour patch. ****While they will work for either eye they can be made for one eye or the other specifically for permanent or medical use. They are molded and will not rub, irritate or touch the eyelid.**** They would work for either eye and have an adjustable strap with a secure buckle to keep it in place. There are no elastics that will overstretch with time.  Thank you and happy pirating
