Welcome to HCM,
It seems that due to splashing of oil in the eye might given some injury
to sclera or even cornea.
You are advised to consult ophthalmologist
for eye examination as soon as possible as there is chance of having corneal ulcer
which is very problematic for vision if not treated in time.
Meanwhile clean your eye thoroughly with plane water and put antibiotic eye drops every 2-3 hourly.
Ok and bye.
