How do you either keep them turned "upright" or detect rotation for updating the images? Contacts slide around in the eye a bit and their shape keeps them on the eye's lens pretty well, but there's no asymmetrical shape for keep the contact lens from rotating.
- cstuder 15y agoSome lenses, I think mostly the soft ones, are asymmetrical: They are intentionally heavier on the bottom and let gravity rotate them into place.
- gmac 15y agoYes -- those are toric lenses, for correcting astigmatism. Unfortunately it makes them rather thicker and less comfortable than the usual ones.
- mietek 15y agoFunnily enough, I just picked up today my first ever daily disposable lenses for correcting astigmatism. These are the most comfortable lenses I've ever worn, including regular daily disposables.
- jessriedel 15y agoStill, there is going to be a significant amount of shake and sway as you move your eyes around. I wonder if you could correct it in software by tracking the movement of the lens with respect to the eye.
