The Geometry of Astigmatism To grasp the purpose of the axis, you must first understand the physics of astigmatism. This is why proper frame fit and adjustments are just as important as the prescription itself.
What Does Axis Mean Eye Prescription for Your Astigmatism
One meridian might be perfectly focused, while another, perpendicular to it, is out of focus. Understanding what does axis mean for eyes begins with the lens inside your glasses.
