I have several focal points in each eye, randomly clustered together. And unfortunately, there is no correlation (or reason for a correlation) between my eyes.
Imagine not being cross-eyed with two focal points, but with well over a baker's dozen. Even if I could line up one pair of points between my eyes, any improvement would be indiscernible in the mess I see.
Because the focal points are clustered close together, their impact is less at a distance (it just feels hard/impossible to properly focus, like looking through very slightly warped glass), but it is devastating up close. For reading.
Without help, I see so many copies of all the letters, randomly and tightly stamped all over each other, I could stare at a short line of text all day and never figure out what it said.
And this after having better than 20-20 vision at all distances, for most of my life.
(Fun fact: if I am in a dark room, and look at one of those tiny power-on LED lights on some media equipment with enough distance that it is basically a point, I can clearly see all my focal points - and also a dimmer curvy, spaghetti crossover mess of focal Beziers between and around them. My corneas are neither convex or concave. They are chaotic. Evil.)
Fortunately, I have hard gas-permeable "scleral" contact lenses. They form a near perfect cornea for me, so when I wear them, my awesome vision and glyphs live once again. "Scleral" refers to the fact that they are wide enough to rest on the whites (sclera) of the eyes, to completely cover and fill out my lame natural corneas.
So I am in pretty good if inconvenient shape.
But I would absolutely love it if this new method allowed my corneas to be reshaped. Any improvement would be a big deal.
(There is surgery where corneas are soaked with a binder, which is fixed with a laser, that strengthens them and stops/slows Keratoconus from getting worse. But it cannot recover what has already been lost.)
ʕ•ᴥ•ʔ Bear vs. ʕ·ᴥ·ʔ Build EAR
The compilation database tool (https://github.com/rizsotto/Bear), is extremely helpful. It got CCLS/clangd working for me over multiple in-house build systems at a vfx studio.
It also is super helpful for debugging. I have used it a lot alongside a script which converts a compile_commands.json to a sequence of commands, so I can edit them individually without fiddling with the build system, and then once fixed (such as adding a flag to one TU) try to find the way to do that in the build system.
