LogMAR visual acuity (VA) was assessed under monocular vision with best spectacle correction, in two different controlled lighting conditions: photopic (85cd/[m.sup.2]) and mesopic (3 cd/[m.sup.2]).
The evaluation room was maintained with background lighting conditions in the mesopic range, and stimuli ranged from 0.161 to 3.211 cd/[m.sup.2].

During twilight, both our rods and cones operate (mesopic vision) and complement each other by providing a mix of fairly good resolution and faint-light sensitivity.
The potential benefits relate to mesopic vision--the transition in the human eye from cone sensitivity to rod sensitivity in lower light situations.
