What does the acronym WTR stand for in astigmatism terminology?

Explanation:
WTR describes astigmatism where the vertical meridian is steeper than the horizontal. In prescription terms, the cylinder is oriented along the horizontal axis (about 180 degrees) to compensate for the difference between the two meridians. This pattern is common in younger eyes and contrasts with “Against The Rule,” where the horizontal meridian is steeper. The other options aren’t used in standard astigmatism terminology.
