The Importance of Peripheral Sight

20/20 vision does not always mean healthy eyes. In fact, many people with glaucoma, retinal detachment, stroke or other vision-threatening conditions can have significant visual impairment despite 20/20 reading vision. Hidden blind spots can go unnoticed in the corner of our sight for quite some time unless we pay close attention to what’s happening in the peripheral part of our visual field – a part that accounts for more than 80% of our retinal and optic nerve function.
