Corridor Conundrums Optimising Progressive Addition Lenses
Available from: 1/10/2024 (AEST)
Activity Outline
In her roles as Training Manager and then Professional Services Manager at Rodenstock, Nicola Peaper was often asked about corridor lengths in progressive addition lenses (PALs) and the impact they have on intermediate and reading areas, along with the problems that patients encounter. In this article, Ms Peaper examines how corridor performance is affected by lens design and compensation. Additionally, she discusses considerations when choosing a corridor length and the implications of fitting decisions.
Learning Objectives
- understand how Minkwitz astigmatism and corridor length affects the width of a corridor
- recognise that different methods of insetting a corridor affects the usable width available to a patient
- understand how giving preference to visual tasks at distance, intermediate and near working distances affects the positioning of aberration on a lens
