I don't think twitching is a sign of pink eye. Twitching means the people lost control of the fast spansm of their eyelids. It refers to some certain nerves or muscles problem. While pink eye is the infection and inflammation of conjunctiva in eyes, possibly caused by bacterial or viral infection or allergies. People with pink eye might have symptoms like increased sensitivity to light, pain in eyes, grittiness, red and watery eyes. There seems no direct connection between eye twitching and pink eye. Eye twitching happens and goes naturally but pink eye requires a treatment in most cases. Eye twitching is not contageious, while pink eye caused by bacterial or viral infection is highly contageious. If patients got the pink eye for herpes virus infection, it probably would last for months. In most cases pink eye won't cause very severe result of vision impairment. Warm compress could help with pink eye.
