Down: 1) Power of coordination by which the images received by the two eyes become a single image.2) A physical property of light apparent in its color. Violet has a short wavelength, red a long wavelength. Different tissues absorb different wavelengths preferentially, making the various lasers useful for specific purposes.4) A refractive error that prevents the light rays from coming to a single focus on the retina because of different degrees of refraction in the various meridians of the eye.6) Ability to use the two eyes simultaneously to focus on the same object and to fuse the two images into a single image that gives a correct interpretation of its solidity and its position in space.7) The bending of light by a lens or optical system. Also is the process for determining the needed power of a prescription lens for an individual.8) The eyes rotate outward simultaneously.11) Scattering of light passing through a heterogeneous medium, or being reflected irregularly by a surface. 15) Return or bending of light by a surface such that it continues to travel in the same medium.20) The branch of physics which deals with the phenomena of light.21) Refractive error in which light rays entering the eye focus at a point in front of the retina (nearsighted). Across: 3) Axis along which light rays travel from an object to the macula.5) A gradual lessening of the power of accommodation due to a physiologic change that becomes noticeable about the age of 45 years.9) Transparent object(s) or substance(s) through which light travels.10) Transformation of radiant energy into a different form of energy, usually heat, as it passes through a medium. Light that is neither transmitted nor reflected.12) Adjustment of focal power of the eye from distance to near vision.13) Refractive condition in which no refractive error is present; all light rays focus on the retina.14) Simultaneous ocular movement in which the eyes are directed to an object in the midline in front of the face.16) Act or ability of seeing; sight17) Looking directly at an object so that its image falls on the macula.18) Entire area that can be seen without shifting the eye.19) Process of directing the visual axes of the two eyes to a near point, with the result that the pupils of the two eyes are closer together.22) Refractive error in which light rays entering the eye focus at a point beyond the retina (farsighted).23) The action of brightening an object with light.24) Passage of radiations through a medium or substance. Transmission can either diffuse (light is scattered in all directions) or regular (without diffusion).25) General anatomic adjective meaning of or related to the eye.
