Try stopping current contact lens if you have them, try an oral antihistamine like
Zyrtec, Claritin, or
Clarinex, try an allergy drop like Patenol, Pataday, or Elestat, find out if you have allergies by seeing an allergist, then control any allergens that you are exposed to, see an ophthalmologist to be evaluated for possible oculare allergies, and also to be checked out for dry eyes. Good Luck.
