Crevice corrosion refers to the attack of metal surfaces by a stagnant solution in crevices, for example in nuts and rivet heads. When dust, sand and other corrosive substances are deposited on surfaces, they create an environment where water will accumulate and corrode the part. It can happen between two metals or between a metal and a nonmetal.

Typically, both allergies and infections cause a severe redness or 'meaty' appearance of the conjunctiva. This is caused by edema or fluid build-up and an increase in the size and number of blood vessels within the tissue. Either allergies or infections cause the eye to discharge or 'weep.'. The consistency of the discharge often helps determine its cause. Usually infections caused by bacteria, fungi, etc., create a thick yellow or greenish eye discharge. The eyelids may actually stick together when held shut.
