Degrowth is really about scaling back on the over-the-top way we live. It's about finding a sweet spot where people live well but not at the expense of everything else. It’s cool and useful that solar is cheap, but degrowth means chill on the endless buying and using and discarding stuff, be sustainable and make sure everyone gets a fair shake, not just those who can afford it.
Could it be the prevalence of ophthalmologists instead? I assume it was really hard to get good medical care100 to 200 years ago, not to mention the cost of glasses.

It's orthogonal. More doctors would mean more diagnosis. But more short distance indoors fixed focus screen work stress on the eyes would also mean more patients.
Too little time outdoors
Research has found that spending time playing outside as a child may reduce your chances of becoming short-sighted, and existing short-sightedness may progress less quickly.
This may be related to light levels outdoors being much brighter than indoors. Both sport and relaxation outdoors appear to be beneficial in reducing the risk of short-sightedness.
Excessive close work
Spending a lot of time focusing your eyes on nearby objects, such as reading, writing and possibly using hand-held devices (phones and tablets) and computers can also increase your risk of developing short-sightedness.
An "everything in moderation" approach is therefore generally recommended. Although children should be encouraged to read, they should also spend some time away from reading and computer games each day doing outdoor activities.
I'm not the grandparent poster, but I think that "even if they moved at a fraction of speed of light" refers to the responding civilisation's space vessels, not their return signal.
Let's say you receive an EM signal from a sentient specie.
If you pinpoint its origin to light years away, you know they already had a lot of time to progress past this technology. A good response if you plan on eliminating them would not be a fleet: you'd better setup and direct a huge gamma-ray burst in their general direction.
So the destructive response could come at the speed of light with a little delay at first.
Essentially it is, build doorways that attract targeted traffic in some categories, and sell that traffic to porn sites... sounds simple, very hard to do profitably and requires both decades of experience, being extremely smart, and some luck.
