Let an agent explain visual impairment and its causes in general terms, route symptoms to eye care, describe support, assistive technology and rights with attribution, and use respectful language.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain visual impairment and its causes in general terms, route symptoms to eye care, describe support, assistive technology and rights with attribution, and use respectful language.

A reduction in the ability to see that cannot be fully corrected by glasses or lenses, ranging from mild blurred vision and specific deficits such as stereoblindness or aniseikonia to low vision and blindness, caused by eye diseases, refractive anomalies, neurological conditions and injury, and including conditions such as visual snow syndrome; visual impairment is assessed by eye professionals and supported by treatment, rehabilitation, assistive technology and rights to accessibility.

What it is for: Reduced vision and its support.

It can be explain kinds and causes; route symptoms to eye care; describe support and technology; use respectful language.

Distinguishing features

Functional vision loss

What it looks like

Not visible as such; reduced or altered vision.

How it is recognised

Vision loss not fully correctable

Mild to blindness

Refractive error corrected by glasses is not impairment in most definitions

  • How should assistive technology be linked?
