What does that mean? I`m also looking for the pronunciation of OR. It`s not even on howjsay.com and I was able to find all the other medical pronunciations there. Wonderful to know what these ODs and OS, etc. mean. The explanation is very helpful. I`m just wondering, are “oculus dexter,” “oculus sinister,” and “oculus uterque,” Latin or other languages? Thank you.

OD = Oculus Dextra OS = Oculus Sinistra OU = Oculus Uterque. means Pupillary Distance. This is the distance between your students` centers. It is measured in millimeters. The measurement ensures that when you get your glasses, you look through the right place in your lenses.

If I checked the right eye during an exam by covering the Lefy and the left eye with the right, and they are both 20/20. Is it correct to set OR 20/20 and OS 20/20? Or. can I document OS 20/20? In other words, if they both tested 20/20, do I have to document them separately? Or can I just set OR 20/20? Thank you it was really great how you explained all these icons and comments.

It only appears once in your prescription because the extra power is the same for both eyes. The value is usually between +0.50 and +3.50. If you only need your glasses to correct myopia or farsightedness and not for reading, you may not need this prescription. I buy contacts and the website I buy them from asks for Right Eye (OD) and Left Eye (OS), then there`s a drop-down list under each and I`m pretty confused what it is? Could someone explain to me what the drop-down lists are that have -1 to -10? I really don`t understand what it is and I can`t buy the contacts until these fields are filled in. Very nice explanations. No need to guess for me. The Southpaw trick helps to remember OS It is read as OO-TER-KWE, Oi-KU-LUS (yes, Oi) OO-Ter-kwe.

The number can range from 1 to 180, where 90 represents the vertical position and 180 represents the horizontal position. The numbers only describe the position of astigmatism, they do not explain the strength of your recipe.
