Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. The irritation you are seeing could be due to an allergy or trauma. I would recommend using an antihistamine eye drop such as Zaditor (ketotifen fumarate) and see if this makes a difference. If this does not, I would recommend having the veterinarian check for corneal ulcers and other signs of trauma in the eye. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
