Light hypersensitivity and technology in autism can be a challenging combination, particularly in a world where screens are part of everyday life. Many autistic individuals experience discomfort or distress when using devices such as tablets, computers or televisions due to the brightness, flickering or glare they produce.

This response is often linked to screen sensitivity, where visual processing becomes overloaded by artificial lighting and backlit displays. Even short periods of screen time can cause headaches, eye strain or irritability, especially when brightness settings are too high or content includes rapid movement or flashing images.

The role of light sensitivity in digital use

Understanding light hypersensitivity and technology in autism is essential for making digital tools more accessible and comfortable.

Difficulty with Prolonged Use

Using screens for extended periods can lead to fatigue and visual discomfort. For some, this may result in avoiding educational software, online communication or entertainment. These visual triggers can limit opportunities for learning and connection if not addressed.

Adaptations That Can Help

Simple adjustments like reducing brightness, using screen filters or enabling dark mode can make a big difference. Scheduled breaks and limiting screen exposure during periods of sensory overload can also improve comfort and focus.

Recognising the connection between light hypersensitivity and technology in autism allows for more mindful and inclusive use of digital tools.

Visit providers like Autism Detect for assessments and recommendations that support screen use while respecting individual sensory needs.
