People with low vision have limited residual vision that can be greatly enhanced through high levels of magnification. Current assistive technologies are tailored for far field or near field magnification but not both. In collaboration with L.V. Prasad Eye Institute (LVPEI), a wearable, optical-digital assistive device was developed to meet the near and far field magnification needs of students. The critical requirements, system architecture and design decisions for each module were analyzed and quantified. A proof-of-concept prototype was fabricated that can achieve magnification up to 8x and a battery life of up to 8 hours. Potential user evaluation with a Snellen chart showed identification of characters not previously discernible. Further feedback suggested that the system could be used as a general accessibility aid.
