摘　　要：利用紫外-可见吸收光谱技术,对红、黄、蓝三种色系中颜色深浅不同且焦度为零的眼镜片,进行了紫外-可见光吸光度的研究;并从医学角度研究比较了人配戴同一色系颜色深浅不同的镜片对立体视觉的影响。研究发现:黄、蓝两色系的镜片,深色样品和浅色样品在紫外光区吸光度基本一致;在可见光区550nm处,深色样品的吸光度大于浅色样品的吸光度。红色系的镜片,在紫外光区浅色样品吸光度高于深色样品吸光度;在可见光区550nm处,浅色样品吸光度仍然高于深色样品的吸光度。人配戴黄、蓝两色系的浅色镜片,其立体视觉优于配戴此两色系中的深色镜片;人配戴红色系的深色镜片,其立体视觉优于配戴此色系的浅色镜片。结果表明:眼镜片颜色深浅对立体视觉的影响,主要取决于人类眼睛最敏感光波550nm处镜片的吸光度,吸光度愈高,镜片对立体视觉的影响愈大。Glasses with zero focal-length lens and different shades of red, yellow and blue were studied in terms of absorbance by UV-Vis spectral absorption method. The effect of lens with different shades of the same color on stereoscopic vision was comparatively studied from the medical view. The study has shown that, for yellow and blue lens, there is no difference in the absorbance between the deep-color and light-color lens in UV; at 550 nm, the absorbance of deep-color lens is higher than that of light-color lens. Whereas, for red lens, the absorbance of light-color lens in UV is higher, and at 550 nm, still higher than that of deep-color. Those with light-color glasses of yellow or blue have much better stereoscopic vision than those with deep-color glasses, while the case is inversed as to those wearing red glasses. The conclusion can be drawn that the effect of lens with different shades on stereoscopic vision depends on the absorbance of lens at 550 nm, and the higher the absorbance, the stronger the effect.
