Some 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.
