A daily replacement contact lens simplifies the care of the lens by eliminating the need for cleaning. You insert the lens in the morning and at night you throw it away. No need for rinsing, rubbing or soaking. Also no need for expensive multipurpose solutions and cases.
In terms of health benefits, by throwing away your contact lens everyday you significantly decrease your risk of infection. This is for two reasons. One there is less time for germs to attach and reproduce on the lens. Second there is no case for germs to contaminate and then contaminate the contact lens. Overall the use of daily replacement contact lenses is a healthier and more convenient choice.
