Omnifocal eye-glasses need two-year’s development
The eyeglasses will include infrared sources and sensors to determine the inter-pupillary distance of the eyes, a processor and liquid crystal materials to adjust the refractive index of the lenses.
"The glasses will need personal fitting. Like current multifocal glasses, a customer would need a prescription for far vision correction and for the ‘addition’ part for maximal close-distance correction. The glasses would then be customized to this prescription," said Yariv Hadded, CEO of Deep Optics, in email correspondence with eeNews Europe. "It would be possible to update the prescription from time to time. I still can’t say who and how the prescription updates would be carried out – there are several options," he added.
Built-in wirelessly rechargeable batteries would power the glasses with a battery life of at least a few days is the development target. "We’re designing the glasses to consume very little power, and the look will not be bulky, as we’re talking about vision correction glasses, which must be light and fashionable."
The eye tracker system uses infrared LEDs to illuminate the eyes so that the sensors can read the distance between the inside edges of the left and right eye pupils. This inter-pupillary distance is used to determine at what distance the viewer is trying to focus and to drive the liquid crystal to alter its refractive index and achieve focus at that distance.
"We received an investment from a local ‘angel’ when the company was established. We’re now completing a seed/A round to complete a working model. When this is up and running, we’ll raise another round to complete the product," Hadded said.
