The contact lenses have a strict life circle, but their life span is calculated from the date when they are opened. However, it is difficult to recall the validity date, wearing the expired lenses is harmful to eyes that is all users always worry about.
The smart container will help people to record all the information of their contact lenses, such as the open date and expire date. When they start to use a new pair of contact lens, they can set the details by the phone to remind themselves. There is a screen inside the mirror to show the left days, which is like a countdown board.
