Summary
Clinical assessment of a new optical element for presbyopia compensation - the Light Sword Lens.
Detailed description
Healthy dominant eyes of presbyopes were examined for visual performance. The examination was performed in the ophthalmic trial frame, which included assessment of 3 trials: reference (with lens for distance correction); stenopeic (distance correction with a pinhole ϕ=1,25 mm) and Light Sword Lens (distance correction with a Light Sword Lens). In each trial, visual acuity was assessed in 7 tasks for defocus from 0.2D to 3.0D while contrast sensitivity in 2 tasks for defocus 0.3D and 2.5D.
