Why you shouldn't sleep with your contacts in

Here’s your semi-regular reminder to take your contacts out before hitting the hay. In the new Annals of Emergency Medicine, researchers detail six cases of people who didn’t take their lenses out. One man who told doctors he slept in his contacts several times a week — and swam with them in — developed bacterial and fungal infections that left his eye inflamed. A young girl developed a corneal ulcer that left her with scarring after she slept in contacts she bought without a prescription at a drugstore. Another man wore the same contact lenses for two weeks straight, slept in them often, and didn't disinfect them every day. He developed an infection and ended up needing a corneal transplant.
