An ophthalmic device for improving a person's ability to distinguish colors comprising: a holographic element; a substantially transparent substrate in optical communication with the holographic element, and wherein the holographic element is disposed on the substantially transparent substrate; a positioning component, coupled to the holographic element, and configured to position the holographic element to an active position with respect to an eye of a person; wherein an image, having light of a first visible color wavelength and light of a second visible color wavelength, and passing through the holographic element is viewable by the eye when the holographic element is in the active position; wherein the holographic element and transparent substrate are arranged such that at least a portion of the second visible color wavelength is diffracted by the holographic element into the transparent substrate and trapped therein by total internal reflection so that, with respect to the image viewed without passing through the holographic element, the relative brightness of light of the second visible color wavelength is less than that of the first visible color wavelength; wherein the difference in relative brightness between the first visible color wavelength and the second visible color wavelength enhances the ability to distinguish colors in the image; wherein the second visible color wavelength is between 450 nm and 600 nm, wherein at least about 40% of the light of the image that is in this wavelength range is removed upon passing through the holographic element; and wherein at least 60% of the visible light of the image that is not in the wavelength range is not removed upon passing through the holographic element. a holographic element; a substantially transparent substrate in optical communication with the holographic element, and wherein the holographic element is disposed on the substantially transparent substrate; a positioning component, coupled to the holographic element, and configured to position the holographic element to an active position with respect to an eye of a person; wherein an image, having light of a first visible color wavelength and light of a second visible color wavelength, and passing through the holographic element is viewable by the eye when the holographic element is in the active position; wherein the holographic element and transparent substrate are arranged such that at least a portion of the second visible color wavelength is diffracted by the holographic element into the transparent substrate and trapped therein by total internal reflection so that, with respect to the image viewed without passing through the holographic element, the relative brightness of light of the second visible color wavelength is less than that of the first visible color wavelength; wherein the difference in relative brightness between the first visible color wavelength and the second visible color wavelength enhances the ability to distinguish colors in the image; wherein the second visible color wavelength is between 450 nm and 600 nm, wherein at least about 40% of the light of the image that is in this wavelength range is removed upon passing through the holographic element; and wherein at least 60% of the visible light of the image that is not in the wavelength range is not removed upon passing through the holographic element.
