First of all, I am sorry for the late reply.
Given your cat's symptoms, it is likely to be a symptom of a viral infection.(herpes virus, chlamydia, calicyvirus). In particular, the characteristic of viral infection is off and on for a while.
In order to identify the above causes + bacterial infection or corneal infection, you need to visit a nearby animal hospital for accurate diagnosis and treatment.
Your cat needs to wear a neck collar to prevent scratching. Wipe your cat's eyes with sterile physiological saline or artificial tears containing hyaluronic acid.
If the symptoms do not improve, you should seek treatment from a veterinary clinic in your area.
