The only reason I had heard of it was because my car has it built into the navigation system. So, I can enter a W3W coordinate and my car will appropriately route me.
It's supposedly beneficial when trying to locate a particular person. They can just send you their W3W, the car can read it off the SMS, and automatically provide routing.
I have not used the capability, but explored it when I first got the car since I had never heard of W3W.
At Kaiser, you just have to walk into any member services office and request. It doesn't happen right then, but I believe in a few days you get a thumb drive with all of your records on them.
However, the law allows the doctors to redact certain portions in your copy that they feel could be harmful to you.
Has the bug been fixed where it doesn't disable? I had to track down why my Nvidia GPU was being used all the time and killing my battery. Turns out it's iTerm2 and it isn't disabling the renderer correctly.
There's currently a bug with multi-GPU based MBPs and the new metal renderer. The new metal renderer causes it to always use high performance graphics whether plugged in or not. I had to debug why my battery was dying faster than usual and traced it back to iTerm2 and the metal renderer.
The developer was working on the fix, but I have not seen a fix announced in the release notes yet.
I always was corrected to 20/15 when I wore glasses and could actually be corrected in the office setting to 20/5 (fairly rare). I was very particular about my vision, similar to you. I haven't had issues with it being 20/20 now, but I do wear glasses for driving because I like the clarity.
I was at that point when I had it done. The only problem with having that bad of an eyesight, they have to use the laser for longer. It helped I had extra thick corneas, but the surgeon I went to said some folks can't have the surgery with eyes that bad.
Of course, that was 15 years ago, so maybe different guidelines now.
I had Lasik done at a university teaching hospital by a surgeon who had done thousands of surgeries. This was in 2003. Every follow-up was by a resident and then the full surgeon. I had significant dry eyes and blepharitis (probably from the dry eyes) for about 12-18 months.
15 years later, I can still see 20/20 in one eye and 20/25-30 in the other. I still occasionally have dry eyes and blepharitis. I wear glasses at night while driving to feel comfortable and I do get halos at night. My left eye, when it is dry, I get slight double vision.
Ultimately, I'm OK with having had it done and don't really regret it. However, folks who ask me about it, I tell them if they can still wear contacts, not to have it done.
I could only wear rigid gas permeable contacts. Being a computer programmer who doesn't blink often looking at the computer (like everyone), I wore ulcers on my eye. So, could only wear glasses. I was legally blind without them, so I feel like I'm in a much better situation now, albeit with some downsides.
With how bad my eyesight was, I will definitely need reading glasses. I'm in my early 40s now, and am starting to show signs of it.
