Spectacle Measurements

Spectacle Measurements

There is only one way to be sure your spectacles will;

  • fit you comfortably
  • look good
  • and do what you want them to do.

That is to try them on and talk through with an Eye Care Practitioner how, when and what you need your spectacles for.

The first step of being measured for your new spectacles is to be measured for the correct strength of corrective lenses that will be fitted into your chosen frame. In the UK this must be done by an Optometrist who is registered with the GOC.

  • Then follows a conversation about the best form and spectacle lens material that will suit your needs, lifestyle and pocket.
  • Then comes the fun part – selecting a style of frame that you like, that suits your face and will work well with your corrective lenses.

Historically when frames were custom made, or at least came in a variety of sizes, opticians took many facial measurements so that when you collected your new specs they fitted you perfectly without too much tweaking.

Modern frames are usually manufactured in just one size so it is important that the frame you choose is a ‘good enough fit’ so it can be easily adjusted to fit you comfortably and to securely hold your lenses in the correct place to give you clear and comfortable vision.

The advent of ‘one size fits all’ spectacle frame does not mean that facial measurements are no longer needed. Some measurements (such as the PD) must still be physically taken and recorded as part of the dispensing process, other measurements are assessed relative to the fit of a standard frames and the dispensing Optician will use his or her experience to decide whether or not a chosen frame can be modified to fit the wearer.
