Night vision enhancement using a wearable device

1. 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.

2. The method according to claim 1 , wherein the projecting comprises:

receiving a command from the user; and

using the light projecting devices, automatically projecting the red light simultaneously to the each lens of the pair of eyeglasses upon the receiving the command.

3. The method according to claim 1 , further comprising:

calibrating said eyeglasses to determine a threshold for a user, said calibrating comprising:

adjusting a red light projected in a dim ambient light;

measuring and recording the current luminance;

repeating the adjusting, measuring and luminance recording for different ambient light environments; and

obtaining an average value of the measured luminances as a dimness threshold for said eyeglasses.

4. The method according to claim 1 , wherein the pair of eyeglasses includes a built-in camera for recording a luminance of an environment near the user as an image.

5. The method according to claim 1 , further comprising:

activating the projecting by one or more of:

a physical touch on the pair of eyeglasses, a physical motion of the user, or a voice of the user.
