ABSTRACT:
A light source is situated on a headgear device and placed to direct light toward the pupil of the eye at an intensity that causes the iris to constrict, resulting in a smaller pupil. This prevents the light scattering due to ophthalmic surgery or eye injury from entering the eye, thereby reducing or eliminating visual aberrations.
