Primary Outcome Measures

Visual Function
Ultra Low Vision - Visual Function Questionnaire - 50 (ULV-VFQ-50), Aa validated self-assessment scale to measure functional vision in people with ultra low vision. 50 items on a Likert scale, ranging from 1-4, higher scores indicated more difficult (lower visual ability)

Secondary Outcome Measures

Object recognition
Subjects will be asked to reach and grasp one of four objects requested by the examiner, without touching any other object. A total of 10 tests will be conducted. If the test is not answered after two minutes, the test will be considered incorrect. The number of correctly identified objects will be recorded.
Character identification
High contrast letters and numbers will be presented. Subjects will be required to orally identify each letter or number presented. The total number of correct answers will be recorded. Ten individual letters/numbers will be presented.
Orientation and mobility tasks
This task will measure participants' ability to navigate a room and identify distinct objects and features in their environment, such as windows and doorways.
