Chemical Eye Burn Overview. Chemical exposure to any part of the eye or eyelid may result in a chemical eye burn. Chemical burns represent a small percentage of eye injuries. Some burns to the face involve at least one eye. Although many burns result in only minor discomfort, every chemical exposure or burn should be taken seriously. Permanent damage is possible and can be blinding and life-altering. The severity of a burn depends on what substance caused it, how long the substance had contact with the eye, and how the injury is treated.
