According to a study by The MarkeTech Group, 87% of radiologists experience some form of physical discomfort when reading images. Some medical displays come with built-in features (to control ambient lighting or boost display brightness, for example) and non-reflective glass to improve reading ergonomics.
Some of the best medical monitors have been specifically designed to present images within the optimal field of vision to maintain effortless visual acuity. Medical screens are often bigger too so you can view an image in full on a single screen, without the need to pan or zoom. The scale-to-fit capability in many medical screens makes reading more efficient and ergonomic as well.
