How to Order
Spexmaniac have tried to make ordering your glasses online as simple as possible without having to go endlessly from page to page.

When you have chosen your desired frame all you have to do is enter your prescription details and select your lens. Our online security accepts most types of credit cards it's as simple as that.

Your Prescription
Your prescription provides us with your optician's recommendation for clear and comfortable vision. Below is an example of a prescription you will receive from your Optician:


The sphere(sph) specifies the strength of lens required to correct your focus - a plus sphere to correct long-sightedness (hyperopia - difficulty focusing on close objects) and a minus to correct short sightedness (myopia - difficulty focusing on distant objects.)

The cyl and axis compensate for an astigmatism. So what's an astigmatism? An astigmatism is where the eye is shaped slightly like a rugby ball not a perfect sphere like a football. This just means the eye has difficulty focusing at certain angles.

The Add, short for Reading Addition, is the additional correction required for reading, this can be used to make either reading glasses, bifocal glasses or varifocal glasses.

A Prism is to try and correct a lazy eye and indicates a more delicate condition. If your prescription contains a prism we recommend you have your frames glazed at your opticians because accurate measurements will need to be taken when you're wearing the frames. We are happy to sell you the frames unglazed of course.

The PD, or Pupilliary Distance, is the distance in millimeters between the centre of your pupils, this isn't a major factor at lower prescriptions (roughly - spheres and cyl's less than two) unless you have exceptional features. For higher prescriptions it is recommended because it enables us to make your spectacles as effective as possible.

You will sometimes see two values, one PD at distance and one PD for near vision (reading.)
If you do just put the details in the notes section of your prescription.
We recommend that you contact your optician to get your PD reading, if not you can measure it yourself as below

Your Pupillary Distance (P.D.)

This measurement is necessary to ensure the correct positioning of your lenses within the frame you have chosen. Have a friend* measure the distance from the centre of the pupil (black dot) in one eye to the centre of the pupil in the other eye. It's like measuring a line connecting the two black dots.

To measure your PD:
1. Place the millimeter ruler on the bridge of your nose.
2. Have a friend face you about arms length away.
3. Have your friend measure the distance between the centre of your pupils (the black dots in the middle of your eyes).


4. (Or you can do it yourself simply by looking in the mirror).
