How to select the correct size of flip-up sunglasses

Selecting the right size of flip up sunglasses is simple.

First measure your glasses

Take these measurements of your glasses (in millimetres):

  • Width and height across the centre of one of the lenses
  • Total width of your glasses, measured from the outside of one lens to the outer edge of the other lens

Select the appropriate size of flip ups in our range

Now visit the flip up sunglasses overview page and click on the shape and lens size that most closely resembles your spectacle lenses.

You will now see a page with full details of your selected flip up, including a choice of lens colours and size. Scroll down this page to check that the overall width of the clip-on sunglasses is sufficient to cover your spectacles.

You can also view and download our Flip up sunglasses size guide showing the lens measurements of all the models.

How we measure our lens sizes

Ideally you should select a shape / size of flip up sunglasses that gives a small overlap when clipped onto your glasses, as illustrated below.
