Diameter: 14.3mm

The diameter measured in millimetres is the length of your contact lenses from one edge to another. Wearing a lens with the wrong diameter may result in irritation.

Before you can get your contact lenses, you will need to go to your optometrist for a professional eye exam. This test will give your optometrist the information they need to identify your contact lens prescription, which is vital for ensuring you get the right lenses for your eyes.
