When spraying aerosol etch primer check which direction the nozzle is pointing before spraying It dont half sting your eyes :'(
If in doubt you should go and get them checked, at least at your local walk in centre if you don't want to go to A&E. You can't mess about with eyes and I'm sure they would prefer you to go and be looked at.
Kate would say get them checked she's an optomorist she recently had a patient with enzime burns from dishwasher powder .
