Feedback: Blur sensitivity interactive

Clinical Practice
Responses to the interactive CPD on the concept of blur sensitivity and eye care

In two articles looking at blur sensitivity, Professor Edward Mallen defined blur sensitivity, blur adaptation and blur discrimination1 and then looked at how blur sensitivity can influence aspects of the refraction undertaken during the routine eye examination.2 These two articles were then used as the source material for an interactive CPD exercise.

Blur sensitivity is a measure of the ability of the visual system to detect blur. In research experiments, blur sensitivity can be assessed subjectively using relatively simple equipment, and can be expressed as a dioptric threshold. Such experiments are generally conducted monocularly and under cycloplegia and with a standardised artificial pupil.
