IXI’s autofocusing lenses are almost ready to replace multifocal glasses

IXI has developed prototype autofocusing glasses that automatically adjust between distance and reading prescriptions using liquid crystal lenses and cameraless eye tracking technology. The lightweight frames use infrared LEDs and photodiodes to detect eye movement and convergence, consuming only 4 milliwatts of power while switching prescriptions almost instantly. Designed for age-related farsightedness affecting people over 45, the glasses could eliminate the need for bifocals or progressive lenses, with IXI planning to launch this luxury product through opticians sometime next year.
