(来学网)被测者屈光矫正度数为-3.00DS/-1.00DC×180,老视试验性近附加度数为1.50D,NRA/PRA为+1.50/-2.00,近用眼镜度数为
  • A.
    (来学网)-1.25DS/-1.00DC×180
  • B.
    (来学网)+1.25DS/+1.00DC×180
  • C.
    (来学网)+1.00DS/+1.00DC×180
  • D.
    (来学网)-1.75DS/-1.00DC×180
正确答案:
D
答案解析:
ADD=试验性近附加+(NRA+PRA)/2=+1.50+[+1.50+(-2.00)]/2=+1.25D,只在球镜上做加减,-3.00+1.25=-1.75DS,所以近用处方为-1.75DS/-1.00DC×180。
