To add prescription lenses, choose your preferred option by clicking on the relevant button at the top of this page and then complete the information boxes that appear by matching the correct parameters from the drop-down menus with those on your dispensed prescription. Please read through the information below before you proceed.

If there is nothing written in some or all of the CYL (cylinder) and Axis boxes on your prescription, please select 0 from the menu where relevant. See the section below on 'Pupillary Distance' for information on what to enter here.

SPH (sphere) and CYL (cylinder) readings are always accompanied by a plus or minus sign. It is very important that you choose the correct plus or minus parameter from the menu for each reading. Sometimes if the readings are minus, the sign will be written above the numbers by your optician.

Is My Prescription Suitable?

Pro Performance Plus sunglasses can be used for any regular prescription where the SPH (Sphere) requirement is less than, or greater than, 4.5. Due to the curvature of the tinted lenses, they will not be suitable for those with very strong prescription requirements that exceed 4.5.

They are also suitable for bifocal, varifocal and prismatic lenses but please note, we cannot add varifocal or prismatic prescriptions ourselves - please buy the sunglasses only and refer the work to your optician.

If you choose to order line bifocals, we will make a segment that stretches up to 8mm in height from the bottom of the lens, for your 'reading' part. If you would like this segment to be smaller or larger, please contact us with your specific requirements.

PD (Pupillary Distance)

This is the distance, in millimetres, between the centre of your eye pupils, when measured across the front of your glasses. PD's typically fall in the range of 55 up to 70mm. If you choose to have us make up your prescription sunglasses, it helps if we know your PD but in many cases it isn't essential. Opticians measure PD during an eye test, but they do not usually put the result on a prescription dispensed to their clients. You can ask your optician what your PD is, but they are not legally obliged to tell you, and they are often reluctant as they do not want to encourage you to spend your money elsewhere.

The good news is, you can measure your own PD quite easily. With your regular glasses on, ask someone to hold a ruler up against your glasses and measure off, in millimetres, the distance between the centres of your eye pupils. That's all there is to it.

If you do not know what your PD is and you are having difficulties obtaining or measuring it, you can leave the box blank. Should we need to know an accurate PD we will contact you.

How Long Does it Take to Make My Prescription?

Turnaround times from date of order is typically 7 - 10 days for UK orders, and a little longer for overseas.

I Am Not in the UK - Will You Still Add My Prescription?

Yes! Our full prescription service is available to customers worldwide and there are no extra fees.
