A new screen displays the highest resolution humans can perceive.
Now for people who use bi- or varifocal lenses comes the latest development from a Finnish startup: ‘autofocus’ glasses.
Its lenses are cut for users’ distance vision and feature embedded liquid crystals in a large circular area in the centre.
Sensors in the frame send invisible infrared light to the eyes, using the reflection to identify the viewing angle.
If wearers look at something close by, a voltage from the frame’s integrated battery is applied to the lenses. It rearranges the liquid crystals accordingly and the area comes into focus.
The voltage then drops for objects viewed in the distance. Sales are slated for next year.
