Abstract
The transmission properties of the ocular media are important for various aspects of vision research. Many age-related changes in visual function are in part due to the alteration in transmission properties of the ocular media as a consequence of the normal aging process (e.g. Weale, 1963; Werner and Wooten, 1980). In particular, there is a greater preretinal transmission loss for short wavelength light than for middle or long wavelengths. Recent investigations have also shown that certain eye diseases produce a selective loss of sensitivity to short wavelengths as an early manifestation of visual dysfunction (Adams, 1982; Applegate et. al., 1987; Heron et. al., 1988; Johnson et. al., 1989). It is therefore necessary to distinguish the amount of short wavelength sensitivity loss that is due to the ocular media from the portion that is due to early pathologic neural changes.
眼介质的传输特性对视觉研究的各个方面都很重要。许多与年龄相关的视觉功能变化部分是由于正常衰老过程导致的眼介质传输特性的改变(例如，Weale, 1963;Werner and Wooten, 1980)。特别是，短波长的光比中波或长波的光有更大的视网膜前传输损耗。最近的调查还表明，某些眼病导致选择性地丧失对短波长的敏感性，这是视力功能障碍的早期表现(Adams, 1982;Applegate et al.， 1987;Heron et al.， 1988;Johnson et al.， 1989)。因此，有必要区分由于眼介质引起的短波敏感丧失的数量与由于早期病理性神经改变引起的部分。
