Described herein are devices, compositions, and methods for improving color discernment. In particular, devices and methods for correcting color blindness comprising a hologram that enhances the ability to distinguish a desired first bandwidth by decreasing the transmission of a second bandwidth. Advantageously, the device appears not tinted to outside observer.

Described herein are novel azo-benzene type chromophores. The chromophores are useful in photochromic compositions comprising a polymer matrix and a chromophore, wherein the chromophore is a novel azo-benzene type structure. The photochromic composition is photoresponsive upon irradiation by at least one wavelength of laser light across the visible light spectrum. Photochromic devices which comprise the novel azo-benzene type chromophore compound show significantly higher photoinduced birefringence, higher diffraction efficiency, and brighter images than devices that comprise well known azo-benzene chromophores. The photochromic composition may include a liquid crystal.
