Portable electronic vision enhancement systems in comparison with optical magnifiers for near vision activities: an economic evaluation alongside a randomized crossover trial

To determine the incremental cost‐effectiveness of portable electronic vision enhancement system (p‐EVES) devices compared with optical low vision aids (LVAs), for improving near vision visual function, quality of life and well‐being of people with a visual impairment.
