Blind people may choose to turn on lights in their homes for various reasons, even though they cannot perceive the light visually. Here are a few reasons why a blind person might turn on lights:
Environmental cues: Blind individuals often rely on environmental cues to navigate and interact with their surroundings. Turning on lights can help create a consistent and predictable environment, allowing them to better orient themselves and move safely.
Assisting sighted individuals: Blind individuals may have sighted family members, friends, or visitors in their homes who require adequate lighting. By turning on lights, they can provide a comfortable environment for others.
Energy efficiency: Some blind individuals may still be mindful of energy usage and prefer to turn on lights when needed and turn them off when they leave a room, regardless of their inability to see the light.
Other sensory benefits: While blind people cannot see the light, they may still experience other sensory benefits from having lights turned on. Illuminated spaces can provide a sense of familiarity, promote a feeling of safety, or enhance the perception of the ambiance through indirect lighting.
Ultimately, the decision to turn on lights depends on the individual and their specific circumstances and preferences. Some blind individuals may have their own unique routines and ways of managing lighting in their homes based on their personal needs and experiences.
