正常色觉（CVN）允许识别多种表面颜色，精确的波长辨别，以及在无数设置中实现最佳安全性和性能所必需的颜色信息[1]。CVN来源于三种视锥细胞：蓝色（短波长，S）、绿色（中波长，M）和红色（长波长，L）。遗传性色觉缺陷（CVD; 8%男性，1/200女性）如下：L视锥细胞缺失（原盲，1%男性）; M视锥细胞缺失（绿盲，1%）;视锥细胞敏感性移位（原盲异常：L向M移位，1%;绿盲异常：M向L移位，5%）[1，2]。获得性CVD发生在许多眼部疾病中[3，4]，并且可以是认知障碍的生物标志物[5]。锥细胞对比敏感度（CS）使用大号字母量化CVD的类型和严重程度[2-5]。我们扩大了锥CS更多的字母大小（锥视力，VA;小写字母CS）。开发了一种综合评分来量化一系列字母大小的色觉，以改善遗传性和获得性CVD能力与视觉需求的匹配。锥细胞特异性（L，M，S）CS功能的潜在研究和临床应用。计算机生成的VA和CS图表显示在经校准的Microsoft Surface计算机上，基于CIE色度和亮度（CS-100色度计，Konica Minolta）的测量结果显示仅对L、M或S视锥可见的字母，然后转换为视锥激发和视锥对比度[2，3]。VA图表如下：0.1 logMAR/行，5个字母/行，0.02 logMAR/字母正确读取。L和M锥（LM）图如下：20/190至20/15（0.98至-0.12 logMAR），8%对比度。S锥图如下：20/240至20/50（1.08至0.38 logMAR）和64%对比度（对比度来自改良的Innova Systems，Inc.测试;由于其稀疏的视网膜分布，S锥使用更大和更高的对比度字母）[2，3]。CS图表如下：10行，5个字母/行，logCS降低0.15/行，每个字母正确率为0.03 logCS。LM对比度范围：16- 1%，S：128- 8%。大号字母CS如下：LM，20/324，S，20/430 [2，3]。小写字母CS如下：LM 20/68，S 20/180。测试是在91.44 cm的暗室中进行的双眼习惯性矫正。数据
Normal color vision (CVN) allows recognition of numerous surface colors, precise wavelength discrimination, and color information essential for optimal safety and performance in myriad settings [1]. CVN derives from three cones: blue (short wavelength, S), green (middle wavelength, M), and red (long wavelength, L). Hereditary color vision deficiency (CVD; 8% males, 1/200 females) is as follows: L cones absent (protanopia, 1% of males); M cones absent (deuteranopia, 1%); and shift in cone sensitivity (protanomaly: L shifted toward M, 1%; deuteranomaly: M shifted toward L, 5%)[1, 2]. Acquired CVD occurs in many eye diseases [3, 4] and can be a biomarker for cognitive impairment [5]. Cone contrast sensitivity (CS) quantifies type and severity of CVD using large letters [2–5]. We expanded cone CS with more letter sizes (cone visual acuity, VA; small letter CS). A composite score was developed to quantify color vision across a range of letter sizes to improve matching of hereditary and acquired CVD abilities to visual demands. Cone-specific (L, M, S) CS functions were derived for potential research and clinical applications. Computer-generated VA and CS charts were displayed on a calibrated Microsoft Surface computer presenting letters visible only to L, M, or S cones based on measurement of CIE chromaticity and luminance (CS-100 colorimeter, Konica Minolta) followed by transformation to cone excitations and cone contrasts [2, 3]. VA charts were as follows: 0.1 logMAR/row, five letters/row, and 0.02 logMAR/letter read correctly. L and M cone (LM) charts were as follows: 20/190 to 20/15 (0.98 to− 0.12 logMAR), 8% contrast. S cone charts were as follows: 20/240 to 20/50 (1.08 to 0.38 logMAR) and 64% contrast (contrasts derived from modified Innova Systems, Inc. test; larger and higher contrast letters were used for S cones due to their sparse retinal distribution)[2, 3]. CS charts were as follows: 10 rows, 5 letters/row, and logCS decreased 0.15/row yielding 0.03 logCS per letter correct. LM contrast range was as follows: 16–1%, S: 128–8%. Large letter CS was as follows: LM, 20/324, S, 20/430 [2, 3]. Small letter CS was as follows: LM 20/68, S 20/180. Testing was binocular with habitual correction in a dark room at 91.44 cm. Data were
