Scientists invent micrometers-thin battery charged by saline solution that could power smart contact lenses
Scientists from NTU Singapore have developed a flexible battery as thin as a human cornea, which stores electricity when it is immersed in saline solution, and which could one day power smart contact lenses.

You only have to cry once a day to power your contact lenses!
47Perfect for all wage slaves in the us then!

Who doesn't want everything you see to be recorded, all while getting an ad overlay directly over your eyes?
29this type of technology could be revolutionary and restoring people's eyesight as well
26While pouring salt into your eyes to power it!
-2Saline is what you are supposed to wash your eyes out with when you get something in them in addition to being what contacts are stored in every night
5Saline is isotonic and, short of a large electrolyte imbalance, shouldn't cause any/very little irritation to your eyes. And if you're hyponatremic to the point of saline solution causing eye irritation, you have much more immediate and life threatening problems to attend to than risnsing your peepers out

Oh hey look. A solution in search of a problem.
26Or a lot of new problems awaiting to happen.
A literal chemical battery in my eyes? No thanks.

Very cool technological achievement, but eye-batteries don’t necessarily sound all that safe, non-corrosive/toxic or not, it’s still a constant reaction to create and store electricity in a very vulnerable location.
25Great. Hopefully by the time smart contact lenses come out (if ever) I'll be dead so I don't have to worry about another tool that can be used to spy on you for not only the government but for the large tech companies looking for the most intrusive ways to steal your info on the daily.
17Introducing Windows Lens....we see what you see.
12Every road sign is replaced with an ad for Bing.

Would you be able to close your eyes to not see anything/ads? I don't know much about the tech, but I would assume a light is being emitted from the contact lenses and since that's behind your eye lids...
9Of course you can close your eyes and turn off ads for as low as $19.99/mo
17I have no idea but I think anything that emit light would drain the battery to quickly.
I would imagine it would more like a e-paper screen.
6I have no idea how these work, but one hack idea off the cuff:
You get the light for free. At least when your lids are open; that's how vision works. A cheap digital watch lasts ages on a tiny coin cell because the polarisation of the LCD, which passes or blocks polarised light, takes minimal energy. Stack up a passive polariser, and the active LCD-like layer, (and maybe a second passive layer?) and you can cast selective shadows on the retina.
This gives you monochrome "smart vision" in the same sense as a monochrome Casio wristwatch. No idea how to tackle issues of focus at such a short focal length, or achieving any sort of active display let alone colour.
Maybe the whole thing is a pipe dream crackpot idea.
6Light intensity is inversely proportional to the square of the distance. A light that's only a few microns away from your cornea would look incredibly bright even with minimal power.

I'll take rating 3 with low light enhancement, image link, and flare compensation.
8No doubt so we can have ads directly attached to our eyeballs.
8Can’t even close my eyes to not see ads anymore smh
4Or, we can make an IRL ad-blocker

Doom on lenses when?
5Hard pass
3All is fun and games until you get the blue screen of death.
