Pupillary Distance
This is the distance between the centre of the two pupils, normally expressed in millimetres. Having an accurate value means the eye is looking through the centre of the lens, making vision clearer. This value should be available from your own optician.
Unfortunately however, many opticians are reluctant to provide this pupillary distance to prevent their patients from going elsewhere. Therefore, if you prefer, we can make your glasses using an average value. We make hundreds of frames successfully using the UK average PD. Alternatively, you can measure your pupillary distance (PD) quite easily yourself. Use a millimetre ruler horizontally and measure from the centre of one pupil to the centre of the other pupil. If you can get a friend to help, it may be easier. You should be able to record a figure in millimetres (normally between 50 and 75mm).
Please note that if you have a particularly high prescription with significant deviations from the norm, you may experience greater difficulty adjusting to an ‘average’ pupillary distance. In this case, we shall advise and make recommendations after you have placed your order.
