CPO TEST EXAM QUESTIONS AND CORRECT
ANSWERS 2026
Simple Myopic Astigmatism - ANSWER ->The refractive condition where
one point of focus falls on the retina and the other point of focus falls in
front of the retina.
Compound Myopic Astigmatism - ANSWER ->the refractive error which
results in two point of focus falling in front the retina example: -1.00 -
2.00x090
Mixed Astigmatism - ANSWER ->The refractive condition in which light
comes to two points of focus where one point is in front of the retina,
and the other is behind it.
Simple hyperopic astigmatism - ANSWER ->one meridian focuses on the
retina while the other, in theory, focuses behind the retina
