1 1.1 Prescription Examples Below are the examples from various high street opticians. All prescriptions are same; the only difference is they are presented in different way. Prescription contains enough information to prepare your glasses. These examples will help you to identify how your prescription looks in terms of layout so you can enter relevant information in the prescriptions Prescription Example 1 In this example the right is represented by the top row of values and the left by the second row of values. In the top row, the right 's Sphere (SPH) value is 2.50, but the minus sign above it means this is actually The right Cylinder (CYL) value is given as Cylinder values always have 2 decimal places, and opticians often omit the decimal point, so the value 100 means This figure also has a minus sign above it, so the resulting value we enter is Both s have an Axis (AXI) value of 180. Neither has a Prism/Base value so these fields should be left as "Not applicable". The prescription shows a Reading Addition, or Near Addition () of This value describes the additional correction required to provide clear vision at very close, or reading distances, and is used particularly for varifocals, bifocals, or reading glasses. In this example, the ermediate Addition (used for intermediate distance correction) is blank and these fields should be left as "Not applicable". Since there is only one Addition value (as opposed to one value for each ), both the right and left s should be set to in this case. 63 mm

1.1.2 Prescription Example 2 NHS In this example there are two sets of values provided: Distance, and Near. It is the Distance values that should be entered into the prescription form.

2 1.1.2 Prescription Example 2 NHS In this example there are two sets of values provided: Distance, and Near. It is the Distance values that should be entered into the prescription form. If you are ordering varifocals, bifocals, reading or intermediate glasses, then you will also need to enter the Reading (Near) and ermediate Additions. The ermediate Addition value of is provided on this prescription in the Comments box underneath, and this should be assumed to apply to both s. The Near Addition is not provided as a separate value. However, we are given the Sphere (SPH) values for each in the Near row of values. We can calculate the Near Addition from these, so they should therefore be provided in our Additional Information box on the prescription form, as follows: Near Addition not provided on prescription, but Near SPH values are: : Left: Should be figure come in column 63 mm Prescription Example 3 The top row of values represent the right (denoted by the (R), and the second row is for the left (L). There are no Additions, or Prism/Base values shown, so these should all be left set to "Not applicable".

No Prism/Base values are provided so these should be left set to "Not applicable". No ermediate Addition is provided.

3 63 mm Prescription Example 4 In this example we have Sphere, Cylinder and Axis values for both s in the top section. No Prism/Base values are provided so these should be left set to "Not applicable". No ermediate Addition is provided. However, a Near Addition of is given for each. The details given in the bottom section of the prescription, labelled "Aided VA", are not required and do not need to be provided to us. 63 mm Prescription Example 5

- This time the signs have been written ABOVE the numbers - they are still just standard +/- signs - Also, sometime optician write 100 instead of 1.00. It should still be entered as '1.

4 - This time the signs have been written ABOVE the numbers - they are still just standard +/- signs - Also, sometime optician write 100 instead of It should still be entered as '1.00' with a decimal point - There is only one value for Near, this should be entered for both s Prescription Example 6 In this example, the right values are given in the top section of the prescription, and both the Sphere and Cylinder have minus signs (-) above them, indicating that they are negative values. The left is given in the second section, with a negative Sphere of Note the value "DS" given for the left Cylinder. This means "Dioptre Sphere", and simply means that the Cylinder value is zero. The left Axis value is blank, which means that too is zero. A Near Addition () of is given for right and for left. A Pupillary Distance () of 75mm is also provided. 75 mm More unusual figures

5 Sometimes figures like this appear on your prescription. These are not needed to make your lenses. Some prescriptions have this figure, which looks like a sideways 8. This means 'infinity'. And you should select 'infinity' from the list. This prescription also has some figures scrawled underneath these are Additions for both intermediate and near distances. Even though it's a single figure, it applies to both s. This would be written like this: Here's the above prescription entered correctly online G2H

6 However, in some case your optician may have given you your "complete reading prescription" as well as your "complete distance prescription". If this is the case your prescription will have two complete rows of figures as pictured below. If your prescription looks like this and all you require is single vision reading glasses simply enter the bottom row of figures in the SPH CYL & AXIS boxes on the website. If you require Bifocal or Varifocal Glasses we will need work out your reading addition for you and tell you what to enter online in the Near/Add boxes (The difference between the 2 prescriptions).
