Explanation
Analysis: Elderly people with presbyopia have impaired vision, are sensitive to light, and have reduced hand dexterity. When selecting a table lamp, ease of operation and comfortable lighting should be considered.
Option A features a modern minimalist table lamp with intense, non-adjustable lighting and small buttons for the switch. The intense, non-adjustable lighting can irritate the elderly's sensitive eyes, causing discomfort and potentially exacerbating presbyopia symptoms. The small buttons are difficult for the elderly with reduced hand dexterity to operate, making it challenging for them to accurately press the buttons to turn the lamp on or off, which would significantly inconvenience their use and fail to meet their actual needs.
Option B features a pull-string switch, soft and even light, and multi-level brightness adjustment, making it ideal for elderly people with presbyopia. The pull-string switch is simple and intuitive to operate; elderly people can easily turn the lamp on or off by gently pulling the string, without requiring precise hand movements, thereby reducing operational difficulty and making it convenient for elderly use. The soft and even light does not irritate the eyes of the elderly, creating a comfortable lighting environment that helps protect their eyes. The multi-level brightness adjustment feature allows the light to be adjusted according to different scenarios and needs, such as lowering the brightness during the day when there is ample natural light and increasing it at night for reading, meeting the elderly's lighting needs in various situations. This makes it an ideal choice for a bedside table lamp in an elderly person's bedroom.
Option C features a complex design with multiple functional buttons but cumbersome operation. While smart table lamps may offer various functions, the complex design and complicated operation steps can confuse the elderly and make it difficult for them to master. Elderly people may not require excessive complex functions; too many buttons and complicated operating procedures may instead increase the difficulty of using the lamp, preventing them from using it smoothly and failing to provide a convenient lighting experience, which does not align with their usage habits and needs.
Option D: A retro kerosene lamp-style desk lamp with dim and flickering light. The dim light fails to meet the elderly's lighting needs for reading and daily activities. The elderly may have difficulty seeing clearly, leading to mobility issues or even accidents. The flickering light can cause eye strain, and prolonged exposure to such lighting may further damage the elderly's vision. Additionally, the retro kerosene lamp-style table lamp may pose safety hazards, such as the risk of fire, making it unsuitable for the elderly and unable to ensure their safety and comfort.
