• SPH (Sphere): this will signify the amount of lens power, which is prescribed to correct farsightedness (+) or nearsightedness (-).
• ADD: this refers to the added magnifying power, which is applied to the bottom part of the lens to correct presbyopia.
• CYL (Cylinder): this indicates the amount of lens power, which is for astigmatism.
• Axis: this is required for astigmatism. It describes the cylindrical power positioning of your lenses.

After, you need to get the measurement of PD. PD refers to the distance between your pupils and it is usually gauged in millimeters. To ensure the right positioning of the lenses on your eyeglasses, the online optical shop needs your PD.
