I got my eyes checked today, and I’m just curious as to what the titles on the sheet that he gave me, mean.  
Heres what the peice o’ paper kinda looked like…

(the /\ is a triangle)

* * *

Sphere CYL Axis /\ ADD |  
-0.75 -0.25 105 |

| -0.75 -0.75 73 |
| --- |

Don’t know what it means, but try using the {code} {/code} tags (with square brackets rather than curly) to format your table.

```auto

It preserves spaces
between letters and
lets you line
things up more easily 

```

You’ll still have to preview a few times to get it just right.
