Autistic individuals have difficulty processing and responding to information from their senses, as well as difficulties with communication and social interaction. Visual problems are also very common.
Often, the signs of these vision problems can be masked by the behaviors that autistic individuals use to cope with the sensory overload of the world around them. The behaviors that are attributable to both autism and vision problems can include lack of eye contact, staring at spinning objects or light, fleeting peripheral glances, side viewing, and difficulty attending visually.
