The sphere column is often abbreviated as SPH. This is the lens power needed to fix your vision. A minus sign (−) next to the number means nearsightedness (you see better up close and need distance correction). A plus sign (₊) indicates you are farsighted (you see better far away and need your near vision corrected).

This is an important question because this is related to the eyes and gives answers related to different changes in the human eye. The CYL stands for "Cylinder". The AXIS stands for "Axis" and SPH stands for "Sphere". All these are used for the distance correction measurement. There are two vision conditions, nearsightedness, and farsightedness.

What is AXIS in prescription? An AXIS will only be found on your prescription if there is a CYL value for the same eye. The AXIS, in degrees, is a number between 0 and 180. It is used to correctly orientate the cylinder correction when making your glasses. On some rare occasions, you may find an AXIS value with a decimal place or fraction.

Most eyeglass labs, including ours, cut lenses in the negative (-), and require that any positive (+) cylinder prescriptions be converted into the negative (-) equivalent. 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.

Sphere, or SPH, is an indicator of the lens strength required to correct nearsightedness, farsightedness, or both. This numerical abbreviation represents the lens power you need to address these vision impairments. The term "sphere" emphasizes that these lenses provide spherical correction, equal in all eye meridians.

Also remember that using your spherical equivalent with any amount of 'Cylinder' in your glasses prescription will result in some amount of blurriness. If you're that person who cannot.

Sphere power (SPH) is your base power, and Cylinder (CYL) is added to it for the total power at 90 degrees away from the AXIS. As you can see, your power along your SPH (at axes 173 and 12, respectively) is a bit worse, but the power along 83 and 102 remains unchanged (0.5 + 1.5 = 0.75 + 1.25).

It is measured in diopter and uses (+) for farsightedness (hyperopia) and (-) for nearsightedness (myopia). 4.

If the SPH value is 0.00, or noted by Plano, Pl, or an infinity sign, you do not have a vision distance problem. Typical SPH numbers range between 0.00 and +/- 20.00. The SPH number on a glasses prescription is listed as a positive (+) or negative (-) number. A negative number means that the lens is correcting for nearsightedness, while a.

If an eyeglass prescription includes cylinder power, it also needs to include an axis value, which follows the cylinder power. The axis is defined with a number from 1 to 180. The number 90 corresponds to the vertical meridian of the eye. The number 180 corresponds to the horizontal meridian of the eye. The axis is the lens meridian that is 90.

To find the right reading glasses, add the sphere number to the ADD number. In the above example, for the right eye, this would be -2.00 and +1.75, which equals -0.25. For the left eye, add +1.00 and +1.75 to get +2.75. Next, look at the cylinder measurement and the axis measurement.

This irregularity causes blurred vision at any distance. Therefore, the CYL number measures the amount of lens power needed to correct astigmatism. CYL is also expressed in diopters (D). Just like the SPH number, the CYL number can be either positive or negative. A higher number indicates a higher degree of astigmatism that needs correction.
