DefinitionSmart glasses (スマートグラス) are a kind of wearable device (ウェアラブル端末) worn on the face like eyeglasses that show text or images within your field of view.
ExplanationBecause you can check information while still seeing the real world through the lenses, they are used for step-by-step work instructions when your hands are busy, for navigation and similar tasks. Models that can align displayed information with the positions of real objects are also called AR glasses or MR glasses.
AnalogyIt is as if a small sticky note sat at the edge of your lens, with text appearing only when you need it.
Memory hookGlasses here means eyewear, not drinking glasses.
