Feedback on our managing the non-tol CET module

You were asked for your thoughts on two different non-tolerance cases.

Case study 1

‘After collecting her new bifocals, she returned to the practice the following week complaining of ‘eyestrain and headache’ when reading with the new spectacles. She reported that the symptoms were less severe when reading at home, and that reading her tablet was much easier with the new spectacles. She had no visual complaints regarding the distance vision with the new bifocals.’

This case revolved around the patient with a significant intermediate requirement at work (using the till) for which her new bifocals were likely to be unsuitable. Her new spectacles had an increased addition of +0.50DS but, as often is the case with hyperopes, the distance had a small increased plus requirement too. In effect, this resulted in a 0.75 increase for the near correction which, though fine for evening reading where the working distance was likely to be closer, was also probably the reason for problems resulting from her longer working distances we assume she used in the workplace.
