Over the last few months we have published a comprehensive series looking at the evolution of progressive power lenses. Professor Mo Jalie has shown how the lenses have developed through several generations, each stage representing an adaptation in improving wearability and minimising adverse visual impact. Though necessarily a compromise in some way, progressives have changed to maximise distortion free areas for different viewing distances and angles and to better suit a full range of frame designs.
As patients have different visual demands, it is prudent to have access to a range of different progressive lens designs to be best able to recommend the lens that offers the best solution. This month’s exercise centres around a first time presbyope with a degree of anisometropia and a significant intermediate range demand. Your discussion should therefore address the choice of the best lens, in your view, to recommend to the patient and allow you to develop the argument as to why you have chosen this.
Once you have read through the source material listed below, please attempt the six multiple choice questions on the following page. You will need to score 100% on the multiple choice questions to proceed to the case study question. You can retake the multiple choice questions as many times as you like to achieve 100%. If you pass the multiple choice questions you will need to wait 24 hours before submitting your answer to the case study.
