To “Protect Eyes” is to “Protect a Life”.
Even though the nose and the mouth are protected with a mask, if the eyes are not protected, this is not regarded as all possible preventions of infection. The prevention of infection is not only for you. Once you are infected, your family and other people around you may become infected. The prevention of infection at the medical front is a responsibility to “protect a life” as well as wearing a seatbelt when you drive/ride a car.
