When in a pinch, one can make a tiny pinhole with their fingers for a similar effect.

It comes with the same downside: reading in low light is difficult.

For pinhole intraocular lenses these are implanted in just one eye for the same reason.

I imagine this product would be used in just one eye at a time.

The dosage instructions say to use it in both eyes

Ah that's interesting then. My guess would be that it doesn't close the iris as much then. However the linked does show 16% reporting dim vision, so there's some further work needed there (pupil size varies across the population, and there's the usual variation in dose efficacy.)

The other downside is that generally people read by recognizing word shapes, and at least for me the necessary pinhole is too small to see bigger chunks of text at once.
