Few years back, when my mom was washing toilet with acid.. she felt some irritation.. suddenly her one of the eye got reddish.. she went for treatment, and after some days, the eye came back to normal.
But now, the same got reddish again, after multiple check up with the eye doctor, she prescribed "Prednisolone acetate ophthalmic suspension USP" and she used for a week.. now her eyes are 70% ok.
