Conjunctivitis is typically a bacterial or viral infection of the conjunctiva, the membrane that coats the eyelid and eye, explains Bausch & Lomb. Some people develop the condition because of allergies or in reaction to environmental chemicals. Symptoms include tearing, yellowish discharge, and eye discomfort, itching or burning.

A stye develops when skin bacteria enters an eyelash follicle, MedlinePlus states. A pimple-like bump develops at the eyelash root, says Bausch & Lomb.
