Prescription Requirements

Prescriptions must be dated within the past 2 years and be issued by a registered optometrist. The prescription must show the name of the prescriber, the individual optometrist who carried out the sight test, the practice name alone is not sufficient.

Your prescription must include your PD - Pupil Distance - to ensure correct lens alignment. This information is often included with your prescription but if not you can measure it yourself at home using the instructions below.

How to get your - PD - Pupil Distance

Step 1: Find a suitable ruler and stand in front of a mirror.

Step 2: Close your left eye and place the 0 mark of the ruler in the middle of your right pupil.

Step 3: Looking straight ahead, close your right eye and open your left eye

Step 4: Read off the measurement from the middle of your left pupil - this is your PD

Frequently Asked Questions

How do I get my prescription?

When you have an eye test with a qualified optometrist it is their legal obligation to give you a copy of your prescription. Don't forget to ask them to measure your PD as well!

How do I send you my prescription?

To place your order simply prescription@tens.co with your choice of frame and lens and a copy of your prescription. We can only accept written copies of prescriptions so just scan or take a pic and send it to us as a .jpg .pdf or similar file. Unfortunately we can't accept prescriptions that are typed out by yourself.

What is my PD?

This your Pupillary Distance and measure the distance between your pupils in millimetres. This is needed to get the correct alignment of your lenses.

Can you do my prescription?

We can cater for most prescriptions with SPH between +3.0 and -6.0 and CYL between +/- 2.0. If you are unsure you can send us a copy of your prescription and our lab will confirm whether we can make it!

Do you do varifocal or bifocal lenses?

Unfortunately we are not currently able to do varifocal or bifocal lenses due to the precise measurements required to fit these lenses.

Can I use my contact lens prescription?

Unfortunately we cannot use contact lens prescriptions to make glasses or sunglasses. This is because the measurements for contact lenses are different to glasses and sunglasses.

Where are your lenses made?

Our lenses are made at our independent optical lab in the north of Scotland.

Can you deliver outside the UK?

Yes, we deliver worldwide.

Will I get the non-prescription lens too?
