Seven ways: Dispensing individualised lenses

1 Ask yourself: what do we exactly mean by individualised lenses?
In practice, dispensing opticians often use the words tailor-made, personalised and bespoke in our lens explanations. Individualised lenses often use the latest freeform technology, which takes into account the spectacles’ vertex distance (VD), face form angle (FFA) and pantascopic (P). Due to a surfacing and polishing process, the wearer will experience enhanced visual performance through the calculated compensated powers.

2 Understand the individualised measurements required and their importance.
For prescriptions +/- 5.00D or above, it is best practice to perform the effectivity calculation should we establish a difference between the testing VD and the VD of the chosen frame. This will ensure that the patient is not over or under corrected while wearing the new pair of spectacles. The pantascopic angle must be measured after the frame has been perfectly fitted to the patient in order to ensure the patient is looking through the correct visual axis.
