Understanding your eyes is an important part of caring for your vision. When you get a new prescription understanding it can be a challenge. You may know that you are nearsighted, or farsighted, or that you have an astigmatism, but what do all of those symbols on the paper mean? OD, OS, SPH and CYP? OD is an abbreviation for oculus dexter, latin for right eye. OS is an abbreviation for oculus sinister, or left eye. Your prescription might have the abbreviation OU, or oculus uterque, which is latin for both eyes. A modern prescription might have the abbreviations of RE (right eye) or LE (left eye), but this depends on the clinic or doctor. Sphere (SPH) refers to the power of the lens. It is measured in diopters and is prescribed for nearsightedness or farsightedness. A minus sign (-) means nearsighted, a plus sign (+) farsightedness. Cylinder (CYL) tells the amount of lens power needed to correct an astigmatism. If there is nothing in the CYL column then there is no astigmatism.
When we say 20/20 vision, we mean that a patient has the ability to see clearly at 20 feet, what should normally be seen at that distance. Wile 20/20 is an expression of normal visual acuity it does not mean perfect vision.
