For example, ultraviolet light is converted into fluorescence or phosphorescence. Most optical, media have selective absorption, that is, absorb certain radiation (colors) differently.  \nAbsorptive lenses  \nEyeglass lenses that absorb bright lights. Their purpose is to provide eye comfort against glare.  \nAccess  \nThe brand name for Sola enhanced, near vision lenses. An access lens is a single vision reading lens with an enhanced range (extra close) at the bottom ofthe lens.  \nAccommodation  \nThe act of increasing the dioptric power of the eye by an increase in the power of the crystalline lens to permit objects at different distances to be clearly seen.  \nAccommodative Amplitude  \nThe total amount of dioptric power which the eye or eyes are increased by maximum effort of the ciliary muscle. The dioptric power increase of the near point over the dioptric power of the far point.  \nPage 1  \nGlossary of Optical Terms Compiled by Davis Vision  \nAcrylic (ak krill lex)  \nAn economical lens material most commonly formed by the injection molding process. Lightweight and optically correct  \nAcuity  \nClearness, distinctness, sharpness of vision.  \nAddition (Add)  \nDioptric power added to distance prescription to supplement accommodation for some finite distance; such as reading. The dioptric power of a bifocal segment.  \nAfter-image phenomenon  \nAbility of the eye to retain sight of an image during eye blinks.  \nAgainst motion  \nObjects sighted through convex (plus) lenses move in an opposite (against) direction as the convex lenses are moved from side to side. See also with motion.  \nAge-related macular degeneration (AMD)  \nAn acquired retinal disorder characterized by degeneration in the central (macular) area of the retina. This is the leading cause of blindness in persons over age 65.  \nA-Scan Ultrasonography  \nA noninvasive diagnostic test in which sound waves are used to determine the position of, and distances between, structures within the eye and orbit.  \nAmaurosis  \nBlindness  \nAmblyopia (Am ble o pe ah)  \nLow or reduced visual acuity not correctable. Amblyopia is said to exist if vision is uncorrectable to 20/30 or if vision in one eye is significantly less than that of the other.  \nAmetropia  \nThe refractive state of a static eye in which the secondary focus does not fall upon the retina.  \nAniseikonia (An ih si ko neah)  \nA relative difference in size and/or shape of the ocular images (right eye does not see an object the same size as the left eye) .  \nAniseikonic Lens  \nA lens designed to correct the image size difference.  \nAnisocoria (An I so ko reah)  \nPupils of unequal size.  \nPage 2  \nGlossary of Optical Terms Compiled by Davis Vision  \nAnisometropia (An I so me tro peah)  \nA condition of unequal vision for two eyes.  \nAnomalies (A nom ah les)  \nA deviation from the usual or norm.  \nANSI  \nAmerican National Standards Institute-The organization which is responsible for setting all of the limitation, tolerances, and testing procedures that must be adhered to in many industries, including ophthalmic fabrication.  \nAnterior  \nClose to the front.
