As the name says, single vision lenses provide only one type of vision correction, and are the lenses you should choose if you're either near-sighted, far-sighted or astigmatic, but not if you have two or more prescriptions.
Considerย Single Vision for distanceย if:
You donโt wear reading glasses.ย
Your Rx Script does not indicate an ADD Power.ย
You do wear reading glasses, BUT YOU DO NOT want your prescription lenses to have any reading power magnification. ย You only want Distance Vision correction.
Below is an example of a prescription for someone who likely needs Single Vision glasses. Note that there is nothing in the ADD column.ย

Yourย Rxย Script indicates an ADD Power AND YOU WANT to be able to see clearly into the distance and focus on your phone to read text messages.
