So then does it so confuse your brain that your normal focusing is interfered with ?
I'd imagine it would be like having a transparent sheet in front of you. Probably no more confusing than a HUD on a transparent windshield.

Nits aren't a measure of total light though. A 100 nits huge screen at a distance that covers 20% of my field of vision would be the same as a 100 nits tiny screen close to my eye that covers 20% of my field of vision. Or to put it another way, things don't look dimmer just because they're further away. It's less total light because it covers less of my field of vision .
Fair point, I imagined nits was something like Lumen. But I think it certainly matters, since nits indicate the amount of light (candles per square meter) hitting a board 1m from the source, if the board/eye is only 10mm away, the intensity in that spot is much higher. That said, the area changes much more than the distance I think, so overal brightness is probably still not equivalent to 100 nits (at 1m).

The shoei one is interesting to me, but afaik not yet available. I'm not going to trust my brain at 155MPH to a "move fast and break things" kind of startup.
At 155MPH, I think your eyes should stick to avoiding obstacles.
My dream application: Google maps hud for when I go motorcycling. Right now the options are 1) Mount an arm to the handlebar and risk my phone detaching or breaking in a crash 2) phone is in my pocket so I can hear instructions, but not see the screen. having my phone in my jacket pocket, but transmitting to my contact lens would be pretty great.
I use my Apple Watch which displays large format directions during navigation and gives you a little tap on the wrist when you're nearing a turn. Works great for driving cars or motorcycles, riding bikes, and walking.

Interesting point. I actually find it annoying/redundant in the car, but never thought of the benefit if I were to use it during motorcycling! Thanks for the tip.

I think I can see how you've got here but that's not correct. It's about the light emitted per square meter of the source, not a measure of the light hitting a board some distance away.
Moving a screen closer doesn't make it more intense, because as you move closer it covers more of your vision. Total light increased, but not more intense.

I had lasik in 1999. I was legally blind (uncorrected) in my left eye, and needed a pretty serious correction in my right eye. After lasik, my vision was 20/15 (left) and 20/10 (right). Now, in 2022, I still have no need of glasses, although I'd say my vision has degraded somewhat - still good enough to pass the driver exam uncorrected, however. Night vision is objectively worse after lasik. Poorer light sensitivity,…
What does it do to your near-in sight though ? Can you read ingredients labels ?
