Screen sightedness refers to myopia caused by too much time spent indoors staring at small screens. Screen sightedness指长时间待在室内盯着小屏幕看而导致的近视，即“屏幕近视”。 British researchers coined the problem "screen sighted," referring to a 35 percent increase in nearsightedness since the launch of smartphones in 1997. They believe smartphones are a cause, and warn that the problem will only get worse. 英国研究人员最先提出“屏幕近视”这一问题，并指出自1997年智能手机问世以来，近视现象增加了35%。他们认为智能手机是导致屏幕近视的主要原因，并警告称这一问题只会愈发严重。
