Isopropanol
Sorry, this answer is incorrect. Exposure to isopropanol will not cause blindness. However, isopropanol has other adverse health effects such as nausea, vomiting, and even coma and death. Upon ingestion, the liver oxidizes the alcohol into acetone. Isopropanol can be found in antifreeze, alcohol rubs, cleaners (especially for electronic devices such as drive heads and pins), solvents, disinfectants (sterilizing pads contain a water/isopropanol mixture), fuel additives, and others.
