Abstract
An optical element is configured to be worn in front of an eye of a wearer. The optical element has two main surfaces and includes at least one holographic diffusive element having diffusive properties resulting from spatial variations of refractive index of said holographic diffusive element. The spatial variation of refractive index is greater than 0.001 at at least one given wavelength, on a distance less than 30 μm. An optical equipment includes the optical element and methods for recording a holographic medium onto an optical lens.
