I too suspect things are worse than they were, though I also try to bear in mind that my eyes are older too. My corneas will be yellower and the first hints of cataracts are probably appearing.
I certainly notice it takes me longer to light adapt. There are times when the drops used by opticians to dilate the pupils look very attractive.
But I must admit we did have a stonking night here last month when the stars were crystalline jewels, despite the fact few places are more than 25 miles from a significant town.
La Palma remains my favourite place on the planet – I’ve never been to Chile. 🙂
