It looks like it also improves low-light sensitivity, which is arguably more useful than colour sensitivity.
"Rod sensitivity (the ability to see in low light) also improved significantly in those aged around 40 and over,"
> by far the biggest vision problem due to ageing is long-sightedness.
I had cataracts at a young age, and had my natural lenses replaced with fixed-focus implants. There were lots of positives after the procedure, but the downside was an immediate loss of any ability to focus. (Progressive loss of ability to focus is why long-sightedness becomes an issue as you age, and this is a complete loss of that ability in fifteen minutes.)
It may be that I have a 1.5D (intentional) delta in the two lenses, but loss of focusing ability hasn't been that bad so far. In fact, I can now write this on a laptop without any external correction at all. At least from my anecdotal experience, I'd characterize long-sightedness as potentially frustrating, but easily manageable.
What scares me, though, are retinal issues (the ATP loss described in the paper, as well as others). Treatment options there are generally far less effective and far more intrusive.
