Among the objectives of the study is to validate a framework of ADLs that require near and intermediate vision and better reflect visual capacity, in a special experimental environment of 9 different combinations of light temperature and light intensity.~The final list consists of the following ten basic ADL tasks:~1. Phone Book Search (PBS), 2. Supermarket receipt (SupRe), 3. Book reading (BR), 4. Cellular message (CM), 5. Cellular entry search (CES), 6. Reading computer screen (RCS), 7. Drops bottle reading (DR), 8. Subtitles reading (SubRe), 9. Open door test (ODT), and, 10. Screwdriver test (ST).~The 9 light combinations are the following:~3000 K - 25 fc, 3000 K - 50 fc, 3000 K - 75 fc 4000 K - 25 fc, 4000 K - 50 fc, 4000 K - 75 fc 6000 K - 25 fc, 6000 K - 50 fc, 6000 K - 75 fc
Primary objective of this study is the construction and validation of an experimental environment for the simulation of a variety of near- and intermediate-vision activities of daily living (ADLs) in different combinations of light temperature and light intensity.
