How to read your glasses prescription 


Glasses prescription layouts differ depending on which optometrist you go to, and they can sometimes be confusing, but you don’t need to know how to read your prescription in detail to order your glasses online. 

 

There are just a few key pieces of information you need to know, and you can make use of helpful online tools to measure your pupil distance

 

These are some of the scores and measurements you might need to enter when ordering online. It’s essential to be as accurate as possible when entering any scores and whether they are proceeded by a plus or a minus. 

 

  • OS and OD

OS refers to your left eye, and OD refers to your right eye. 

 

  • SPH

SPH, or sphere, is all about distance. This is the correction for either long or short-sightedness. The number will appear in increments of .25, and either have a plus or a minus sign in front of it. A plus sign indicates long-sightedness, and minus indicates short-sightedness. 

 

  • CYL and Axis 

CYL is an abbreviation for cylinder, and refers to the presence of astigmatism. This is scored in increments of .25 with either a plus or a minus sign. The axis score ranges from 0 to 180 and indicates the angle of astigmatism. This score won’t appear on your script if you don’t have astigmatism.  

 

  • Reading ADD

Reading Addition indicates how much extra power is needed over and above the distance prescription. It won’t always appear on your prescription. The number is in increments of 0.25 and will always be preceded by a plus sign.  

 

If there are any other abbreviations or scores on your prescription, such as a Prism reading, please contact our optician or contact your optometrist for some guidance.

Most sunglasses can be glazed with your prescription, or you can have your prescription lenses built into a pair of sunglasses, giving them the corrective qualities you need.
