In this case, the eye doctor has prescribed -2.00 D sphere for the correction of myopia in the right eye (OD). There is no astigmatism correction for this eye, so no cylinder power or axis is noted. This doctor has elected to add "SPH," to confirm the right eye is being prescribed only spherical power.
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.)
Corning Cable Systems Single-Panel Housing (SPH-01P) is a cost-effective housing for storage, protection and termination of optical fiber cables. The SPH-01P accepts standard LANscape Solutions CCH connector panels and offers protection for the fiber cable and connectors for indoor wall-mount installations.
Sph means Sphere and indicates the basic degree of short or long-sightedness. Minus (-) means you are shortsighted and plus (+) means longsighted. There will also be a number associated with this which could be small or large. The higher the number the stronger the strength of prescription lens required.
SPH (sphere) A + in the box indicates that you are long-sighted which means you find it difficult to see things close to you. A shows that you find it hard to see things that are far away without glasses.

SPH(or Sphere) indicates the eyeglass prescription power, or how strong your lenses need to be to correct your vision. CYL (or Cylinder) indicates astigmatism, a condition where the cornea is irregularly shaped causing blurred or distorted vision. It also tells the lens strength needed to fix it.

SPH Spherical number shows how strong the correction needs to be. CYL Cylinder number shows how much astigmatism you have. AXIS Axis shows the position of the cylinder and will be between 1 & 180. PRISM This shows if you have a muscle imbalance in your eye. BASE This shows the direction of the prism in your lens
Your prescription What it means. On your prescription, as well as some basic details such as your name and date of birth, there will usually be a table that shows your prescription. What the numbers mean . The first number is called the spherical number, and this will show whether you are short sighted (-) or long sighted (+) in each eye.
Next comes "Sphere" or "SPH." This refers to the lens power you'll need to achieve 20/20 (or at least optimal) vision. A minus sign (-) means you are myopic, or nearsighted. A plus sign (+) means you are hyperopic, or farsighted. (If you see no + or - sign, it also means you are farsighted.)
The SPH number corrects for nearsighted [indicated with a minus (-)] or farsighted [indicated with a plus (+)] vision. The CYL number and AXIS number correct for astigmatism. You may also have another field labeled as ADD which corrects for the reading power used in a bifocal or progressive lens.
The SPH (Sphere) box shows a measurement of how long sighted (hyperopic) or short sighted (myopic) you are. If you are short sighted, the SPH value will have a minus (-) sign before it. If you are long sighted, the SPH value will have a plus (+) sign before it. The (D) stands for dioptres which is the standard measurement that is used.

What does "SPH" appearing under Cylinder on my prescription mean? Essentially this means correction for Astigmatism is not required for the prescription being considered. When you enter your prescription during checkout, please select "Not Applicable" for all Cylinder and Axis fields, thank you.
SPH=sphere power CYL= cylinder power or astigmatism If you see the "sph" in the "cyl" box, that means you have no astigmatic correction in that particular eye.

How to Transpose an Rx in VirtualLens 3D: In the Lens Properties dialog, where the current Rx is, click the Calculators button and select Transpose Rx, then select one of the transpose options to convert to plus or minus cylinder form.
Best Answer: SPH is the sphere, or the amount of magnification/demagnification your eye needs to see properly. If you have a positive number, the lens will help with closer images, and a negative, sph optical
If the optometrist wrote "DS" or "Sph" or "Spherical" in the Cylinder space, it indicates no correction and should be entered as 0 on the order form. This means that the eyeball is spherical and has no oblongedness, and consequently has no Cylinder or Axis values.
Rest assured this conversion does not alter the type or quality of the vision correction that your doctor prescribed you. The conversion will affect (change) the SPH, CYL, and AX parameters in your prescription, but will result in the exact same vision correction you were fit for by your doctor.
SPH is an abbreviation of sphere which indicates the power of the lens your doctor is prescribing to correct your vision. If youre nearsighted (myopia), the number will have a minus sign (-).
