If the number has a plus sign (+) or is not preceded by a plus sign or a minus sign, you are farsighted.  The larger the number following the +/-, the stronger the prescription.</div> <div> </div> <div><strong>CYL</strong>(Cylinder/Cylindrical): This indicates the amount of lens power needed to correct astigmatism. This number also can also be preceded by "+" or "-" sign. If "DS" or "SPH" or "spherical" or "PL" is stated at the place of CYL, it means you have no astigmatism. </div> <div> </div> <div><strong>Axis: </strong>This number indicates the orientation of astigmatism and is measured in degrees. It will be between 1 and 180. If an eyeglass prescription includes cylinder power , it must also include an axis value, which follows the cylinder power.</div> <div> </div> <div><strong>Add:</strong> Short for Reading Addition, is the additional correction required for reading. It can be used to make either reading glasses, bifocal glasses or multifocal glasses.</div> <div> </div> <div><strong>PD:</strong> Pupillary Distance, stands for Pupillary Distance, which is the distance between your pupils in millimeters, Your PD is very important for accurately fitting your lenses to achieve vision acuity.</div> <div> </div> <div><strong>Prism</strong>: refers to the prismatic power used to correct vision displacement. It helps to correct some special conditions or eye disorders (like a squint) that require the focused image to move position. The measurement is Prism Dioptre. The value may be as high as 10 and may go up in steps of ½ or 1 Prism Dioptre's.</div> <div> </div> <div><strong>PL</strong>: Plano. Latin for "flat." If this is in the SPH section of an Rx, it means no nearsighted or farsighted correction is needed.</div> </div>
