Which intervention helps individuals who are visually impaired?

Utilizing bright colors is an effective intervention for individuals who are visually impaired because it enhances visual contrast and can make objects and environments more discernible. This option plays to the strengths of those with limited vision, allowing them to identify boundaries, navigate spaces, and focus on specific items that stand out against contrasting backgrounds. Bright colors can also be used to guide attention and provide visual aids that support engagement in various activities, thereby enhancing safety and participation.

In contrast, the other choices do not offer constructive support for individuals with visual impairments. While encouraging physical activity is beneficial in general, it does not directly address the specific needs of visually impaired individuals. Complete silence can hinder their ability to use auditory cues for navigation and interaction. Infrequent environmental cues would likely lead to confusion and disorientation rather than facilitate understanding and navigation in their surroundings. Therefore, using bright colors is clearly the most helpful intervention in this context.
