Adding lights to stair risers is beneficial since it can be hazardous negotiating stairs especially at night. Staircases are often enclosed so light them from the sides or embed lights in the risers as a design element.
A perfectly lit room has three basic layers: overhead lighting task lighting and accent lighting. This bedroom pulls all those together — the chandelier for overhead bedside reading lamps as task lighting and accent lights above the headboard and artwork.
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.
