1. An optical system for a near-eye display (NED), the optical system comprising:
a light-guide optical element (LOE) including a light-transmitting substrate having:
first and second major surfaces parallel to each other,
one or more light input coupling elements configured to couple incident light into the light-transmitting substrate thereby trapping the light between the first and second major surfaces by total internal reflection, and
one or more light reflecting elements configured to at least partially reflect the light coupled into the substrate, the one or more light reflecting elements having chromatic reflectance; and
a light source configured to emit the incident light such that the incident light as received by the one or more light reflecting elements compensates for the chromatic reflectance of the one or more light reflecting elements.
