Understanding Your Prescription

Prescriptions are generally all written in a similar format although the information can sometimes be presented in a slightly confusing manner, particularly handwritten ones.

To place an order with us, you need to select ADD LENSES after you have chosen your frame, then select the type of corrective lenses you wish to buy before filling in your prescription details. Please how How to Order Glasses Online for more details.

There are several options available and we have given examples of how to enter the details in our Order process for each scenario - in general, your Optician will have told you what type of prescription you need when you have your Eye Exam but if you are unsure then don't hesitate to contact us and we can help you out.

If you're only ordering Fashion glasses then you don't need a prescription. Similarily if you want non-prescription Readers (OTC) then you'll only need to provide the required magnification. See Readers (OTC) for details.

We've provided some typical examples of prescriptions along with explanations of how you would enter these on our prescription page. 

Example 1a: Distance – Single Vision prescription

There are several distinct cases for when you would choose Distance - Single Vision in

Example 1b: Distance - Single Vision Prescription with ADD values

Multifocal Example

If your prescription has ADD figures as above (which may also be markes as Near Add or only Near), which are normally seen in prescriptions for people aged over 45 and relate to the need for increased magnification for reading close up small print, but you only wish to buy glasses for Distance Vision then select Distance - Single Vision and simply ignore the ADD figures when you are entering your prescription as below:

However, if you ONLY wish to use your glasses for close-up reading then you should select the Reading - Single Vision option and provide all the details, including the ADD

If, on the other hand, we wish to have both Distance and close-up correction then you should select a Multi-focal option - Progressive, BIfocal or Trifocal.

Example 2: Reading - Single Vision

This prescription could also be for Multifocals, but if you ONLY want single vision glasses for reading close-up then select Reading - Single Vision and the following:

Example 3: Computer - Intermediate

Computer - Int - sample Prescription

Your Optician may recommend Single Vision corrective lenses for Computer Use. These prescriptions are similiar to the Reading - Single Vision prescription in that they have an ADD field but the prescription will be marked INT (Intermediate) instead of Near then you select Computer - Intermediate and enter the prescription as follows:

Multifocal Prescription

Example 4: Multifocal Prescriptions –
Progressive, Bifocal or Trifocal.

The multifocal/varifocal prescriptions correct for distance and also for closer-up readings so it is important clearly indicate as part of the order process that you wish multifocal lenses as these are more complex than single vision lenses.
