    As people age, they often require bifocals or several pairs of glasses to see objects both near and far. Deep Optics, a technology start-up based in Israel, is working on an alternative: eyeglasses that automatically refocus on any target at which the wearer looks. The “omnifocals” adjust focal length by relying on the interaction between an electric current and liquid crystal, a material in which molecules act like both liquids and solids...

    That would be very helpful to those of us with presbyopia which affects everyone eventually.

    I heard of glasses that adjust focus with a dial. How do these know where the wearer is trying to focus on?

    I've tried using the graduated lenses, also the one script in one eye and another in the other with contacts but found all that too distracting. I can still see close up without glasses but when I have contacts in for distance I need reading glasses which I can't use without remembering how as a kid I used to torment my favorite uncle whenever he wore his half glasses. He was a great guy. Miss him.

    I was gonna say it probably monitors the pupil so I clicked the link provide and found this:

    The wearer trains his or her eyes on an object. Infrared sensors on the frames measure the distance between the pupils and send this information to an embedded processing unit that calculates the distance to the object.


    which is way more cool than my uncle's half glasses.
