Dik :
PR = (titik jauh) = 200 cm, S = ~ , S’ = - PR = -200
Ditanya : P = ….dioptri

P = 
 \frac{100}{F}

Jawab :
 \frac{1}{F}  \frac{1}{S}  \frac{1}{S'}

 \frac{1}{F}  \frac{1}{~}  \frac{1}{-PR}

 \frac{1}{F}  \frac{1}{~}  \frac{1}{-200}

 \frac{1}{F} = 0+ \frac{1}{-200}
F = - 200 cm
P = -  \frac{100}{200}
   = - 0,5 dioptri
Jadi Jawabannya D
