The most common mistake we see is the incorrect entry of the '+' and '-' values for SPH and CYL. This is an issue that is often caused by customers entering their prescription incorrectly.
If you feel you have a problem seeing with your new glasses, please ensure you have entered your values correctly. If you notice an error please contact us immediately - attach a copy of your prescription and quote your order number so we can verify where the error lies for you.
Please also ensure you provide details of how you obtained your Pupillary Distance - PD measurement in order to remedy any issues.
