Help with your Glasses Prescription The Sphere The sphere (Sph) specifies the strength of lens required to correct your focus - a plus sphere to correct long-sightedness (hyperopic - difficulty focusing on close objects) and a minus to correct short sightedness (myopia - difficulty focusing on distant objects.)
Indicates your prescription and how powerful the lens must be to correct your vision. If the number in the spherical portion of your script has a minus sign (-), the prescription will be fixing nearsightedness. If the number has a plus sign (+) or is a positive number the prescription will be fixing farsightedness.
