In those early years writers frequently discussed the effects of television on family life. However, a curious myopia afflicted those early observers: almost without exception they regarded television as a favorable, beneficial, indeed, wondrous influence upon the family.
请问上文中的a curious myopia翻译成中文的意思是？在字典中，myopia只有目光短浅；缺少远见的不可数名词的意思，不懂前面如何可以加不定冠词a？看上下文，myopia又仿佛等于they。难道a curious myopia等于一群目光短浅的人？记得一群特定的人的话应该是the+形容词，像the poor之类的。
a curious myopia afflicted those early observers
myopia：抽象名词，意为 “目光短浅；缺少远见；短视行为”。抽象名词被形容词curious 修饰后，变得“形象化；具体化”，这个时候可以加不定冠词。翻译为“一种奇怪的短视行为”。
afflict：困扰；折磨。
