Hi Friend I am Dr Bilal and I am an Ophthalmologist
Welcome to Health Care Magic
I would like to answer your question and your satisfaction is my goal .
As you have mentioned that you accidentally got some gasoline into your eyes , and then you washed them with water and now you are experiencing a blurred vision
. This all could be due to transient corneal injury
. Cornea is basically the transparent part of your eye and it consist of many layers and covered by an epithelium which is replaced every 7 days with the new epithelium . Gasoline splashed into your eyes must have damaged the cornael epithelium . I would suggest you to visit your doctor soon to have a slit lamp examination of your eyes , visual acuity , Tonometry and any further investigations . Meanwhile you need to use Antibiotic eye drops or ointment , some pain killer tablet like Ibuprofen
I hope you will find my answer helpful .
God bless you.
Wish you a speedy recovery.
Best Regards .
