Can magnification help patients with macular degeneration to recognize facial expressions?
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.
