Headsets and head-mounted displays including first and second diffractive elements are described. In some cases, the first and second diffractive elements include first and second grating surfaces, and for at least one wavelength, the first and second grating surfaces have at least one different corresponding diffractive property. The head-mounted display may include two-dimensionally pixelated adjacent first and second display surfaces for displaying images, and first and second diffractive elements disposed adjacent the respective first and second display surfaces. In some cases, the first diffractive element is configured to diffract a first wavelength λ
