Bright idea for dimmed lighting: To make the most of your lighting install the highest-wattage lightbulb possible then dim it down to accommodate the mood and lighting needs. Consider putting dimmers on both overhead lighting and lamp lighting.
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.
I’ll let you in on a little secret that designers use to get that photo-ready finish in a home: layers of light. Just like with clothing and accessories in fashion when creating your interior lighting scheme layering your light sources helps create a rich look that highlights great features and eliminates harsh shadowing. To do that you’ll need an approach that combines many different styles of fixtures and sources.
