Myopia And Astigmatism
How are myopia and astigmatism calculated?
Are they calculated together or separately?
For example:
the limits for CAA/JAR is -5 for myopia and -2 for astigmatism:
if an eye is -5 of myopia and -1 of astigmatism, is that eye is considered as -6 diopters (and then out of the limits), or is it inside the limits because the two components separately can reach the requirements?
Thanx
