I agree with Dr Rakhi that its a form of chemical conjunctivitis
. But pls do not use and steroid
drops without supervision of an eye specialist. There are many pitfalls to doing the same.
Insted the simpler and safer approach would be to use a lubricating drops hourly with a plain antibiotic drop added to prevent infection. You can use some oral pain killer if there is any discomfort.
If there is no relief with the above regimen, then its better to start the treatment under the care of an ophthalmologist.
Hope this helps.
