According to the American Academy of Ophthalmology, wearing glasses will help you avoid coming in contact with your face, which is a primary way to transmit any virus, including the novel coronavirus currently circulating around the world. Not only do contact lens users touch their eyes to put in and remove their lens frequently, they also touch their eyes and face much more than people who don’t wear contacts, said Dr. Thomas Steinemann, the American Academy of Ophthalmology’s clinical spokesperson.

Glasses can also offer a little bit more protection against any airborne coronavirus virus particles, Steinemann said, but it is more possible that one will get infected through their mouth and nose than their eye.

The new coronavirus may cause conjunctivitis, also known as pink eye, an extremely contagious disease. Signs of conjunctivitis include tearing, irritation or burning, blurry vision, red or “pink” in the whites of the eye, blood, mucus and a yellow discharge that can crust over the eyelashes, often holding the eyes together after sleep. Reports from China and around the world indicate that there was also conjunctivitis among around 1 to 3 percent of people with Covid-19. This is worrying because the coronavirus can transmit by touching fluid from the eyes of an infected person, or from objects touched by that individual which then bear the fluid. A pink or red eye may be another warning that one should consider calling their doctor for if they have other tell-tale Covid-19 symptoms, such as fever, cough, or shortness of breath, too.
