Get checked for allergies from your doctor.
There is no such thing as "eyeritis".
Iritis is inflammation of the iris.
Uveitis means inflammation of the middle coat of the eye.
could be an eye infection or eyeritis
There are a number of reasons for this.
It could be an infection, an allergy, conjunctivitis, blephratis, wearing dirty contact lenses.
I would advise you to see the doctor for a proper diagnosis and possible medication if this is an infection.
In the meantime, get some cooled boiled water and clean each eye using some cotton wool, wipe from the middle to the outside of the face. Do not use the same cotton wool for the other eye. Pat dry gently.
