Contact lenses all have expiry dates. Monthly and yearly contact lenses are difficult to remember how long have been used. It is necessary to change a new pair on time in order to protect eyes, otherwise vulnerable eyes will be harmed by bacteria and the lens wear. Hint-lens is a contact lens with special notification elements to remind people of the expiry date. After the valid time, the hint will appear on the lens to block the sight so that people will know it is time to discard it.
