Eyeglass Prescription's

On your prescription, the Spherical, Cylindrical, and Axis columns also contain values. The lens strengths are recorded in the spherical and cylindrical columns in diopters.

If you are like me, and try to read your eyeglass prescription you have no idea as to what it means. The following article, I will try to explain what everything means. First, when an ordinary eyeglass prescription is used to correct refractive errors in the optical system, which creates a blurred image. Then by correcting these errors, the lenses clear the blur image.

Abbreviations:

O.D. can mean Doctor of Optometry, however when it is on an eyeglass prescription it is the abbreviation for oculus dexter, which is Latin for right eye.

Oculus - eye.

O.S. the abbreviation for oculus sinister, which is Latin for left eye.

D.V. is the abbreviation for distant vision.

N.V. is the abbreviation for near vision.

D.V. and N.V. refer to the different corrections for the upper and lower portions of a bifocal lens.
If you have a single vision prescription, then the N.V. portion will be left blank or mark as N/A.

Diopters- A unit of prismatic deviation, being the deflection of 1cm at a distance of one meter.

On your prescription, the Spherical, Cylindrical, and Axis columns also contain values. The lens strengths are recorded in the spherical and cylindrical columns in diopters.  The axis column contains the direction of the cylinder axis written in degrees.  In the areas, for the Prism and Base, these are generally left blank. The Prism and Base are used to treat muscular imbalance in the eye or other conditions, which cause confuse in eye orientation.
