Prescription Instructions

Please see the detailed product information on our website to find out about PD, plus any other restrictions on the use of our eye wear.

*You only need to give us your ‘near add’ readings if you are ordering bi-focal lenses.

Sphere and Cylinder readings will be plus or minus numbers to two decimal places, e.g. -3.25. It is common for opticians to write a minus sign above the number so please check for this carefully. The Axis readings will be whole numbers - in fact, they are angles, written in degrees, although opticians will not normally add a degree sign next to them.

Cylinder and Axis readings are linked together, and refer to patients who suffer from astigmatism. If you do not have astigmatism, the cylinder and axis boxes for either one or both eyes may be blank on your prescription. This is perfectly normal, and if they are blank, you can leave these empty on the above form or just type N/A in the box.
