What does my prescription mean?

Your prescription is a personalised record of any changes in your vision and reading it involves understanding these key components:

• Sphere (Sph): Shows how short sighted (negative) or long sighted (positive) you are.
• Cylinder (Cyl) and Axis: Addresses astigmatism, with Cyl indicating the degree and Axis the orientation.
• Addition (Add): Specifies additional power for reading in multifocal lenses.
• Prism: Corrects eye alignment issues.
• Base: The direction that the prism will be placed when the lens is being made.
