What does axis mean on my prescription?
Video and written answer:
Axis is part of your prescription, and tells an optician in which direction they must position any cylindrical power in your lenses (required for astigmatism). The number shows the orientation or angle (in degrees) from 1 to 180. The number 90 means vertical position, and180 horizontal. A higher number for the axis does not mean that your prescription is stronger it simply describes the position of the astigmatism.
