What is it about?
We studied whether older adults with central visual impairment due to macular degeneration have an easier time recognizing emotions in facial expressions when the faces are magnified. We tested this at the equivalent of viewing faces across the street, across the room or across a table.

Why is it important?
Magnification is a key piece of vision rehabilitation for individuals who have reduced visual acuity. The arrival of head-mounted devices that can provide hands-free magnification during activities of daily living, may potentially be useful in the context of face- and emotion-recognition.
Perspectives
Face perception and the ability of recognizing people at a distance is a frequent rehabilitation goal for low vision patients; however, for now, we have to yet been able to develop reliable and successful strategies or assistive devices that can be used in this context.
