How do you read these complicated things!? Believe it or not, they're actually pretty simple to understand. First things first, remember myopia is not a medical condition, it is a refractive error. Therefore, your "prescription" is much more accurately referred to as vision [[correction]].

==Spherical==

Spherical is the overall correction, in all directions. It is measured in [[diopters]]. A minus value means the lense is used correct [[myopia]] and a plus value means it is used to correct [[presbyopia]]and or [[hyperopia]].

==Axis==

[[Axis]] is the degree at which cylinder values are relevant. The correct cylinder value but the wrong axis value would make the correction pretty worthless! When reducing your correction, you should never ever change the axis, especially if you've had that value of axis for a long time.

If you don't have any cylinder correction, you will not have an axis value either.

==Pupillary Distance==

[[Pupillary Distance]] or PD, is the final set of numbers you need to be aware of. Most likely this is not listed on your "prescription" you will need to ask for it or measure it yourself.
