The first thing you must do is to stop wearing Contact lens(CL). Consult with your ophthalmologist to know whether you have CL induced keratitis
or Allergic keratoconjunctivitis
. In either case avoiding CL till you are completely recovered(usually 1-3mths) is advisable .
Until you see your doctor you can use your prescribed glasses with ,plain lubricant eye drops and wait for the appointment. Donot use any over the counter antibiotic or steroid
or any combination eye drops of them until told so after examination.
And don't worry as it is a treatable condition unless your cornea
is badly infected or damaged due to the lens.
Let us know your prognosis.
