Saline solution is used to aid in the removal of foreign objects or chemicals from the eye, while soothing irritation, stinging, redness, watering, inflammation and discomfort. Remove contaminants such as particles and liquids from your eyes using Reliwash saline eyewash, a non-toxic formula containing 0.9% sterile saline solution. This formula works to replace the moisture in the affected eye, or it can also be used to flush wounds if necessary.
