Spatial contrast sensitivity in adolescents with autism spectrum disorders.

Koh et al. (2010) tested how well teens with autism see faint stripes on a screen.

They used a lab task that slowly fades the stripes until the teen says they vanish.

Both ASD and typical teens joined; no one got training or treatment.

The two groups saw the stripes disappear at the same point.

No sign of the “super vision” some older papers had claimed.

Basic contrast sensitivity looks typical in ASD by adolescence.

Dudley et al. (2019) ran a similar teen lab study and also found no visual-filter gap.

Laugeson et al. (2014) saw the same null in younger kids tested for sharpness, backing the idea that enhanced eyesight is a myth.

Van Eylen et al. (2018) muddies the water: they still find a small local-first bias in ASD, but only on tricky global tasks.

Taken together, low-level vision is intact; any style differences sit further up the processing chain.

You can stop blaming poor scanning or “laser focus” on extra-sharp eyes.

If a learner stalls on a worksheet, look at attention or comprehension, not basic sight.

Use standard fonts, lighting, and contrast; no need for enlarged or high-contrast materials unless an optometrist says so.
