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.

    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…

      Of course you can close your eyes and turn off ads for as low as $19.99/mo

      I 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.

        Light 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.
