1. A sight device for a firearm, said sight device comprising:
a main body that is configured to be mounted onto the firearm;
a lens that is positioned along the main body;
a light source that is positioned along the main body;
a light sensor that is positioned along the main body, said light sensor functioning to capture an ambient light lux value in real time; and
a controller that is positioned within the main body, said controller being in communication with each of the light source and the light sensor, and including a controller memory that stores a brightness adjustment formula,
wherein the light source is configured to emit an aim point onto a first surface of the lens, and wherein the controller is configured to selectively and continuously change a brightness level of the emitted aim point based on an output of the brightness adjustment formula utilizing the real time received ambient lux value to provide a consistent brightness to a human eye viewing the aim point,
wherein the controller changes an output power of a light emitting diode to change the brightness level of the aim point, and the stored brightness adjustment formula comprises:
LED Power=(3.16)n*[(m)*((lux)/(MAXn)+(b)+/−((α)*(β))]
wherein n represents a Lux Segment Number; m represents a System Brightness slope Constant; lux represents Target Ambient Light Data, in Lux; MAXn represents a Maximum Lux Value for the Lux segment Number n; b represents a System Brightness Intercept Constant; α represents a User brightness Offset Constant; and β represents a User Brightness Control level.
