When you switch on a lamp, the brightness in the environment increases, causing the pupil of the eye to constrict, or get smaller. This response, known as the pupillary light reflex, helps regulate the amount of light entering the eye to protect the retina from excessive brightness. The constriction of the pupil improves visual acuity in well-lit conditions by reducing the scattering of light.

Conversely, the covered eye’s pupil may constrict slightly due to the reduced light input. This adjustment helps the uncovered eye compensate for the loss of input from the covered eye, maintaining overall visual acuity.
