Climbing stairs can be difficult for many reasons, including poor lighting; but good lighting can help the person better see the step edges and any clutter on the stairs. Make sure the light is glare-free, or it can be blinding, especially for aging eyes. Also, be sure there's good lighting that's at the same brightness level on the stairs and in adjacent spaces, such as hallways and landings. This will not only help the person to see well and to walk more safely, but it also reduces visual hallucinations and "spooky" shadows he or she may see in dim light. Finally, provide for night lighting that allows the person to adequately see the steps and surrounding areas, but be careful that it's not too bright. Bright light at night can be disorienting – the person may think it's daytime and not want to go back to bed.
