Translucent glass shades on pendant fixtures will reduce glare in the kitchen. Hanging overhead lighting fixtures such as pendants should sit 30 to 36 inches above the island work surface.
Another important aspect of lighting a space for those with diminishing eyesight is visual cuing. Visual cuing provides an additional reference point for judging distance or depth when entering a space or approaching objects. The lighting at the base of these cabinets or toe-kick lighting contrasts well with the dark floor and midtone cabinetry creating a readily visible contrast. But people will just think it's cool.
A floor lamp nestled against a window is a smart substitute for daylight so that when the sun goes down an ambient glow will pour in from a similar direction to balance the central light overhead.
