| 摘要 | An optical device for off-axis viewing includes a contact lens adapted for human eye wear. The contact lens includes a diffraction grating written into or on the contact lens. A peripheral light from a peripheral light source is diffracted by the diffraction grating so as to appear at about a same location as light from an ambient scene substantially in a direction of a central field of view. A wearer of the optical device for off-axis viewing sees simultaneously the peripheral light and the light from an ambient scene as superimposed at least in part over each other. A device-less method for correcting light direction from an ambient light source to a retina of a diseased or injured eye, and a remedial contact lens method for correcting light direction from an ambient light source to a retina of a diseased or injured eye are also described. | ||||||
