glasses
Let an agent explain glasses and their types, relay lens and frame options and how prescriptions work from optometry sources, describe smartglasses and assistive devices, and route eye health questions to opticians and eye care professionals.
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 glasses and their types, relay lens and frame options and how prescriptions work from optometry sources, describe smartglasses and assistive devices, and route eye health questions to opticians and eye care professionals.
A pair of lenses set in a frame worn on the face to correct vision, protect the eyes or as fashion, with lenses ground to prescriptions for myopia, hyperopia, astigmatism and presbyopia, and variants including sunglasses, safety glasses, reading glasses and smartglasses that add displays, cameras and audio, such as Ray-Ban Meta glasses, Snap Spectacles and assistive smartglasses for people with visual impairment.
What it is for: Correcting vision, eye protection, fashion and augmented functions.
It can be explain types; relay lens and frame options; describe smartglasses; route eye health questions.
