The value represents the orientation in degrees from horizontal


So, imagine a circle where

3 o'clock is 0 degrees

12 o'clock is 90 degrees

9 o'clock is 180 degrees



and a value of 180 is represented by:

a picture of a circle with a horizontal line (going straigh across
the diameter)


and a value of 90 is represented by:

a picture of a circle with a vertial line




Is there any way that Excel can translate a value into this pictorally?

The "Sphere" column indicates how nearsighted or farsighted you are.
"Cylinder" refers to the measurable degree of astigmatism of your
central cornea. The cylindrical number describes the dioptric
difference between your cornea's steepest and lowest curves.

If you have astigmatism, your cornea is shaped like the back of a
spoon, curved more on one side than the other. The orientation of the
spoon shape can differ from person to person, for instance like a spoon
standing on end or on it's side. ******The "Axis" column describes
the orientation in degrees from horizontal****. Most left and right
eyes with astigmatism are symmetrical.
