This value only applies to people who haveastigmatism, a common problem with the curvature of the cornea in front of the pupil. The larger this number is, the more significant the level of astigmatism is. More significant astigmatism can mean a greater effect on your unassisted vision quality....

Astigmatism - the mirror is not ground symmetrically about its center (it might be slightly egg-shaped, for example); star images focus to crosses rather than to points. Coma - stars near the edge of the field look elongated, like comets, while those in the center are sharp points of lig...
AXIS shows where you have astigmatism in your eye. How can you tell how “bad” your vision is based on your eye prescription? Generally, the farther numbers are away from ZERO, the more correction you’ll need. For example, if your prescription says -9.00D, that means you are very nea...

If nothing appears in this column, you either don’t have astigmatism, or your degree of astigmatism is so small that it doesn’t need to be corrected. The term "cylinder" means that this lens power added to correct astigmatism is not spherical, but instead is shaped so one meridian has...
