Wave aberration of human eyes and new descriptors
... lens surfaces allow the eye to accommodate, the process by which the eye focuses on near objects. Overall, these changes contribute an extra 10.0 to 15.0 diopters (D) of refraction in the young adult eye and diminish with aging. The optical elements described here work in concert to create an image ...

optical properties of biaxial minerals
... In biaxial minerals there are two optical directions along which the velocities of light rays vibrating perpendicular to each other have equal velocities, and have same RI’s, hence biaxial. RVS OF BIAXIAL CRYSTALS RVS is very complex double surface in 3-D (FIG. 7.1); so sections to this surface are ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
