Lose your bifocals! New eyeglasses adjust optical power in real time
Prototype could be a breakthrough for people experiencing presbyopia.
The more than 2 billion people around the world who experience multifocal vision problems may have reason to rejoice: a new startup says it is developing an all-in-one solution that works more effectively and efficiently than correctives already on the market.
Deep Optics is a 3-year-old Israeli company behind electronic lenses that use sensors to detect what the eye is focusing on as well as the viewing distance – adjusting the power of the glasses to ensure that whatever is being looked at comes into focus, whether near or far.
This is in contrast to the most popular current treatment, which is wearing bifocals or progressive lenses. These lenses have a limited field of view – so people need to move their head to see properly, instead of just moving their eyes. The result can be an annoyance, and often frustrates people wearing glasses.
"The human eye has a natural focusing ability that degrades with age ... The dynamic solution we're developing is actually similar to the human focusing mechanism, and so in addition to its superior lens function, should be even easier to get used to with minimal, if any, adjustment required," explained Deep Optics co-founder Yariv Haddad, an alumnus of Tel Aviv University in Israel.
The company call these lenses Omnifocals, and say they still have work to do to create the finished product. They hope their technology will help people with presbyopia, a common inability to focus up-close that starts to emerge as people reach middle age.
