I think my eyes don't react to the light properly. seem to stay dilated?

Congenital.: You may have a congenital defect in one or both eyes known as an adie's pupil. This is a condition where the iris sphincter muscle does not function symmetrically in the circumference of the iris resulting in a slower constriction of the iris and the persistence of dilation or an irregular pupil or asymmetric pupils referred to as anisicoria. Others just have congenital symmetric pupil enlargement.
