Your Persian's Peepers
Eye drainage, tearing, or discharge is a problem that Persians typically encounter. Due to the shape of the face and head (as well as other factors), Persians often develop sinus problems, such as eye drainage. Usually, it is more of an annoyance to the cat than anything harmful. But if your cat cannot clean off all of the substance, it falls upon you as the owner to help out.
So what works? Simply run a washcloth or paper towel under warm water (do not add soap!) and use it to wipe around your cat's eyes. Depending on the degree of tearing, you may need to do so once in the morning and once at night.
For problems with staining around the eyes, consult your vet before using any cleansers or solutions. A solution recommended by many breeders that can be mixed up at home is an eighth of a teaspoon of boric acid and 8 ounces of water. Shake it up and wet the cotton ball. Be careful not to use too much boric acid because it can irritate your kitty's eyes.
If at-home remedies are not your thing, try a product called Eye Envy. It is a favorite among groomers and breeders.
