Hello, there are mostly two kinds of disposable contact lenses, daily disposable contact lenses and monthly contact lenses. For daily contact lenses, they are meant for daily wear and they should be removed everyday, so they can not be reused and they can be bad for your eyes. While for monthly disposable contact lenese, you are supposed to wear them and change them after one month. So you can reuse them within the month.
No, the disposable contacts are not used again which will be bad for your eyes. You'd better not use them any more. The contact lenses are the products which could be used directly on the surface of the eyeballs. You should take notice of the hygiene. You'd better strict to the regulations of using time of each type of the contact lenses.
