I use PL on a 32" 4K display and have a very hard time discerning and reading the UI, especially in the adjustment panels, even with my prescription computer glasses. I wish there were a way to make the text and UI graphics larger, or at least that DxO would make them brighter instead of the almost invisible gray on gray.
I gather that Photoshop has such a feature but Lightroom doesn’t.
Are you using Windows or a Mac?

I’m using a Mac.
In that case, don’t use the highest resolution. See the displays page in System Preferences
I bought a 4K display because I wanted to view my images in higher resolution. I do down-rez it for non-photo work, but unless it’s at 4K for photo work, 1:1 view of images is smaller than it should be. So, it has to be at 4K for photo work. I want DxO to make the UI high-rez-friendly.
PhotoLab’s UI legibility (or lack thereof) has been discussed a few years ago…when the UI was redesigned for low contrast.

Thanks, found and voted for some earlier requests.
That was one of the most stupid changes ever! 
agreed and it seems to be in line with current UI design ideas. Small print, low contrast, no adaptability etc. are just opposed to what was a great principle: Form Follows Function.
Also, inactive tools are even more difficult to read due to the even lower contrast UI. Great help if you search for the one tool that you need. Luckily, we can mark tools as favourites and build our own workspaces. Both are nice and nice workarounds for a weak UI design.
There is nothing more to add to your comments. Everything is correct.
And when I consider that there have already been a number of feature requests in this respect… 
It’s not just PL’s UI that lacks contrast, there are similar gripes, and multiple requests to do something it, about the low contrast in Affinity Photo’s UI yet the designers persist with their design 
If I used Afinity, I would probably be just as annoyed. But that’s not the case.
At least we have the feature requests here. But I ask myself, what’s the point? The visibility of the user interface is so essential that DxO should seriously think about it. I also reported the problem to support some time ago. Perhaps several people should do this.
Absolutely.
Trouble is, an improved UI would take a fair bit of developer time and at the end of the day it wouldn’t make the the photos being edited better. Meaning it’s not a whizz bang feature that the marketing dept. can laud when launching the next version. Meaning it’s very unlikely to ever reach the top of the ‘to do’ pile.
You’re probably right. But not so long ago, DxO also managed to go in the other direction:
So DxO knows which screw to turn. They just need to turn it back.
The longer I think about it, the more annoyed I get.
I can’t imagine it would take a whole lot of coding to simply make the typeface lighter.
If an app has been well coded, it should only take one or two lines
For those of us with less than perfect eyesight they really need to change both the program and fourms
This was raised many times but just ignored
Above all, it was different before!
