Opaque white spot on the pupil

An opaque white spot on the pupil is a common symptom of cataracts, a clouding of the eye's lens caused by age or injury. It appears as a white, milky patch on the pupil, which can cause the eye to look cloudy. The spot may start small and gradually increase in size, eventually obscuring vision. It can also cause light sensitivity, double vision, and blurry vision. Cataracts can be treated with surgery or medication.
