Abstract
There is provided a method for improving a night vision by operating a pair of eyeglasses comprising: a sensor that detects an intensity of a light near a user; a comparator device that compares the detected light intensity near the user against a dimness threshold; and an onboard projector in the pair of eyeglasses projecting a red light simultaneously into each eye of the user if the detected light intensity near the user becomes lower than the threshold.
