The article states no frequency for it either. What it says the drug does: the 1.25% ophthalmic solution, licensed by the FDA in 2021 under the name Vuity, has been shown to improve near vision by constricting the pupil and so deepening the focus. What it says about the limits: the effect is temporary, running 6 to 10 hours, and it can bring headache, brow discomfort and poorer night vision as the pupil narrows.",
        "Warn about the adaptation period or the patient will abandon the glasses. On the article's account neither bifocals nor progressives are tolerated well at first: they can bring on nausea and dizziness, and because vision quality shifts at the junction between lenses, the patient may misjudge depth while walking. With continued wear the symptoms settle over 2 to 3 weeks. (Presbyopia - StatPearls - NCBI Bookshelf, NBK560568)"
