After completing your eye examination the optician will enter your prescription details like the examples shown. So that we can make your glasses specifically for your vision make sure that you enter them correctly! Especially where + or – is noted.
SPH (Sphere). The correction for long or short sightedness.
CYL (Cylindrical). The correction for Astigmatism.
AXIS An Axis value will only be given if you have a Cylinder value. If you have no Cylinder value then both the Cyl & Axis boxes will be left blank. The axis is a number from 1 – 180.
Opticians all use different forms on which they write the prescription, however, all prescriptions follow a standard format. They will all have fields for Sph, Cyl, axis and Add , you may also see fields for Prism and Base (if you have a prescritpion that has prism values entered, unfortunately we will be unable to manufacture these. All prescriptions are shown for right and left eye separately.

If you do not have astigmatism your prescription would look like this below.

If you require glasses for both distance and reading, you may find that your prescription is shown like this:

You can see that there is an add in the Near part of the prescription form. This shows that you require glasses for reading aswell.
If you need bifocals, you will need to enter the add part of the prescription on the prescription page.
If you require glasses for reading only, then you prescription may read like this:

Here you can see that data has only been entered on the row that is titled "Near".
It is important that you enter ALL details written on the prescription. There may also be a value for your "PD" or pupillary distance. Anything written on your prescription, should be typed into our online order form, put on the mailing document, or related to our operators over the telephone.
Please feel free to enter any additional information or queries in the box provided.
