As my near vision has been downgrading over the last 1-2 years (Getting old), I had a quick look about these eye-drops which aren't cleared in EU yet. To my understanding they work by contracting the pupil (Giving a similar effect as squinting which is also a trick I discovered recently), the main drawback are night/dark vision due to the contracted pupil, and a common side effect are red/dry eye. Unfortunately they don't restore near vision but offer an extra way to manage-it.

Will I try them ? Most likely yes, but I'm affraid that by the time they're cleared in EU, my near vision will have passed the point where the drops help. On the other hand, progressive glasses have made huge progress, and even cheap affordable ones give back a good near-vision without impacting distance. And I would recommend someone to take the plunge asap, cheap OTC readers just sucks (and get a full eye-test, you may end-up with a slight distance correction too).

(EDIT) I have no idea how these drops would work on a near-sighted person. My limited understanding of optic make me thing it may work for light myopia. but the side effect may-means that they're not made for every-day, but for moment where you need both near and distance vision together and don't have progressive glasses yet
