Abstract

Presbyopia is currently an unavoidable visual condition and will be even more severe with the aging generations worldwide. However, our daily activities often need more understanding and awareness of presbyopia. Various visual simulators are intensively explored better to understand others, especially the visually impaired ones. This research proposes an optical solution that simulates two primary visual representations of presbyopia: increased near-point and blurred vision within the near-point range. This initial study reveals the effectiveness of our approach when modulating people under their forties’ near-points over various age modes.
