Visual Under-Sensitivity in ASD (Autism Spectrum Disorder) Children
Visual under-sensitivity (also called visual hyposensitivity) refers to a reduced or delayed response to visual input. Children with this condition may not notice visual details that others easily perceive, or may seem unaware of objects, people, or movements in their environment.
Common Signs:
• Appears unaware of objects, people, or movement around them.
• Frequently bumps into furniture or walls.
• Has difficulty finding objects, especially in cluttered spaces.
• Shows poor awareness of visual boundaries (e.g., coloring outside lines).
• Prefers bright lights, spinning objects, or looking at reflections.
• Enjoys watching moving patterns or light sources (e.g., fans, flashing lights).
• Delayed visual tracking or difficulty following moving objects.
• Trouble with reading or visually guided tasks.
Possible Effects:
• Difficulty in learning through visual cues.
• Poor hand–eye coordination.
• Challenges in recognizing faces, shapes, or letters.
• May rely more on other senses (like touch or hearing) for learning.
Therapeutic Activities:
• Light play: Using torches, light boxes, or glow toys to draw attention to visual input.
• Tracking games: Follow moving objects, bubbles, or rolling balls.
• Contrast-based activities: Use bright colors and high-contrast materials.
• Puzzles and matching games: Encourage focus on shapes, colors, and details.
• Visual scanning tasks: “Find the hidden object” games or treasure hunts.
• Mirror play: Encourage looking at self or objects in the mirror to improve visual attention.
