Need to examine: Pupil size varies with exposure to light and in response to medications. Why are you concerned about the size of your pupil. Do you have any other symptoms about your vision. It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. It would be prudent to see your doctor. Wish you good health!
