色盲有“补救”方法?

来源:华人健康网 | 发布时间:2012-06-16 01:09:24 | www.chinesejk.com

  先天性色盲,无能为力。后天性色盲,多少可做一些“补救”。白内障引起的色觉减低,可以将白内障手术摘除。配戴“有色隐形眼镜”或许可以帮助分辨颜色,但戴它会影响立体感。认清交通号志之位置(例如,横式的红绿灯,红灯通常摆在靠近道路中心内侧,绿灯则摆在靠近道路外侧的位置。直立式交通号志,则红灯摆在最上面,绿灯摆在最下面),可以让色盲的朋友,通过十字路时当做指针。

  后天的学习,可以建立你另一套“色觉标准”,例如原本是红色的,而色盲的眼睛看起来是灰色的,那当你看到灰色时,就记住那是红色的。当然,当你须要精确分辨颜色时,只好请没有色盲的家人或朋友代劳了。
