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.
Claims5
A method for improving a night vision, the method comprising:
- providing a pair of eyeglasses with a sensor that can detect an intensity of a light, the pair of eyeglasses adapted to be worn by a user;
- detecting, by the sensor, the light intensity near the user;
- comparing the detected light intensity near the user against a dimness threshold;
- and
- projecting, by using a light projecting device associated with each lens of the pair of eyeglasses, a red light simultaneously into both eyes of the user if the detected light intensity near the user is below the threshold, said simultaneous projecting of red light into both eyes of the user to prevent a binocular rivalry and phoria.
