What does axis mean on my prescription? Answer: The axis number on your prescription tells your optician in which direction they must position any cylindrical power in your lenses (required for people with astigmatism). This number shows the orientation or angle in degrees from 1 to 180. The number 90 means vertical position and 180 horizontal. A higher number for the axis does not mean that your prescription is stronger - it simply describes the position of the astigmatism. Prescription Was this answer helpful?

In lower prescriptions, the amount of prism induced will be of no consequence and will not cause eyestrain.he first number is the P.D. number we require to make your lenses. The second number (63) is the near pupil distance. This number is only needed when reading glasses are required.
