How to find and read your contact lens prescription

There are two ways you can find your contact lens prescription:
1. From a script that your Optometrist has provided you
2. From the box of your current contact lenses

Contact lens prescriptions can be a little confusing to read. Below are the terms that you may come across and how they match to our ordering page. Not all fields will be required for your prescription.
