OD and OS are abbreviations for 'oculus dexter' and 'oculus sinister'. They're Latin terms for 'right eye' and 'left eye' respectively.


Indicates the lens power needed to correct for myopia or hyperopia, measured in Diopters (D).

Negative (-) numbers indicate myopia or nearsightedness, and positive (+) numbers indicate hyperopia, or farsightedness.

Nearsighted means you see better up close than far away. Farsighted means you see better far away than up close.


The lens power needed to correct the amount of astigmatism you have, which is measured in Diopters (D).

Astigmatism is a common condition in which your eye is curved more steeply in one way instead of being completely round. It can cause your vision to be distorted or blurry at any distance.

CYL can have either a plus sign or minus sign in front of the number, depending on the doctor writing it. They don't indicate nearsightedness or farsightedness.


Orientation (in degrees) in which the cylinder correction needs to be applied to correct for astigmatism.


The additional lens power needed for reading. We calculate this by age and it's always a plus number. +0.00 means you don't need an add correction.

This value is used by eyeglass manufacturers when you order reading glasses, bifocals, or progressives.


The distance between the black center of your left and right pupils (measured in millimeters).
