| 释义 | 〔retinula〕diminutive of Medieval Latin rētina [retina] * see retina 中世纪拉丁语 rētina的小后缀 [视网膜] * 参见 retina〔iodopsin〕A violet, light-sensitive pigment found in the retinal cones of the eye.视紫蓝质；视青紫素：一种存在于眼睛的视网膜锥体上的紫色的，光敏色素〔retinene〕Either of two yellow to red retinal pigments, formed by oxidation of vitamin A alcohols. Also called retinal 视黄醛：两种黄到红的视网膜色素中任一种，由维生素A醇的氧化形成 也作 retinal〔myopia〕A visual defect in which distant objects appear blurred because their images are focused in front of the retina rather than on it; nearsightedness. Also called short sight 近视：一种视觉缺陷，由于它们的图象在视网膜前聚焦而不是在视网膜上，所以远处物体看起来模糊不清的 也作 short sight〔retina〕A delicate, multilayered, light-sensitive membrane lining the inner eyeball and connected by the optic nerve to the brain.视网膜：衬于内眼球的精细、多层、能感光的膜，并通过视神经连接大脑〔peripheral〕Perceived or perceiving near the outer edges of the retina:外围的：观察快超出视网膜边缘的：〔rhodopsin〕The pigment sensitive to red light in the retinal rods of the eyes, consisting of opsin and retinene. Also called visual purple 视紫红质：在眼睛的视网膜棒体中红光感光的色素，由视蛋白及视黄素构成 也作 visual purple〔plexiform〕the plexiform layers of the retina.视网膜丛状的层〔hyperopia〕An abnormal condition of the eye in which vision is better for distant objects than for near objects. It results from the eyeball being too short from front to back, causing images to be focused behind the retina. Also called farsightedness ,hypermetropia 远视：眼睛的一种不正常状态，在此状态中更适合看远处的物体，而不适合看近处的物体它是由于眼球前后距离太短，导致所有图象集中在视网膜后 也作 farsightedness,hypermetropia〔porphyropsin〕A purple pigment similar to rhodopsin, found in the rods of the retinas of freshwater fishes and certain frogs.视紫（质）：淡水鱼以及某些蛙类视网膜棒状细胞内的紫色素，与视紫红质相似〔black〕The achromatic color value of minimum lightness or maximum darkness; the color of objects that absorb nearly all light of all visible wavelengths; one extreme of the neutral gray series, the opposite being white. Although strictly a response to zero stimulation of the retina, the perception of black appears to depend on contrast with surrounding color stimuli.黑色：最小亮度或最大暗度的消色差的明暗度配合；能吸收几乎所有可见波长的所有光的物体的颜色；中性灰色系列的一个极端，白色的相反物。虽然在严格意义上黑色是视网膜对零剌激的反应，但看起来黑色的感应是依靠与周围颜色刺激对比而得来的〔emmetropia〕The condition of the normal eye when parallel rays are focused exactly on the retina and vision is perfect.屈光正常：当平行光线恰好聚焦于视网膜并形成清晰视觉时正常眼睛的状态〔retinal〕Of or relating to the retina of the eye.视网膜(上)的：视网膜(上)的或与其相关的〔pupil〕The apparently black circular opening in the center of the iris of the eye, through which light passes to the retina.瞳孔：暴露于眼睛虹膜中央明显的黑色圆形，光线通过此孔才能达到视网膜〔photopia〕Vision in bright light, mediated by cone cells of the retina; daylight vision.光适就，眼对光调节：通过视网膜的锥形细胞调整亮光中的视觉；光线视觉〔phosphene〕A sensation of light caused by excitation of the retina by mechanical or electrical means rather than by light, as when the eyeballs are pressed through closed lids.压眼闪光，光幻视：通过机械或电子途径而不是通过光使视网膜兴奋从而感受到光，如当眼球被紧闭的眼脸压迫时〔choroid〕The dark-brown vascular coat of the eye between the sclera and the retina. Also called choroid coat ,choroid membrane 脉络膜：眼睛巩膜和视网膜之间深褐色的血管网 也作 choroid coat,choroid membrane〔retinoblastoma〕A hereditary malignant tumor of the retina, transmitted as a dominant trait and occurring chiefly among infants.视网膜神经胶质瘤：视网膜的一种遗传性恶性瘤，作为一种显性特征遗传，主要发生在婴儿中〔photon〕A unit of retinal illumination, equal to the amount of light that reaches the retina through 1 square millimeter of pupil area from a surface having a brightness of 1 candela per square meter.光度：视网膜亮度单位，相当于每平方米有一烛光亮度的表面，通过一平方毫米的瞳孔区域，到达视网膜的光线数量 |
