    • Described herein are hands-free vision aids that may be used for low-vision reading. These vision aids may be beneficial for individuals with low-vision disorders such as age-related macular degeneration, retinitis pigmentosa, and other visual disorders. The vision aids described here comprise an optical system with one or more light sources configured to provide a rectangular field of illumination with high illuminance levels bounded by high contrast perimeter. Such an illumination field greatly illuminates a targeted viewing region while reducing glare that arises from illuminating peripheral regions. Some vision aids use green light with high illuminance values for improving visual acuity and comfort for long-duration reading. The optical system of a vision aid may be configured to fit onto and/or integrate with eyeglass frames.
