Binocular optical device in particular electronic spectacles, comprising electronic camera for automatically setting focus that includes correction of different vision defects

Abstract

Electronic spectacles and visual aids for various areas of application are known, in particular those also comprising microcomputers, range finders and an autofocus function. The aim of the invention is to configure a cost-effective binocular optical device in such a way that an automatic focus that includes the correction of different vision defects can be set. To achoeve this, the inventive device has a frame, at least one electronic camera that is supported by the frame and a motor-adjustable lens system that is located at the front and is connected to the electronic camera. The device is characterised in that vision defects are corrected by adjusting the refractive power of the lenses and / or by setting a focus that includes an automatic adjustment for the reading or working distance. The invention lies in the domain of electronic spectacles and visual aids.

Description

technical field [0001] The invention mainly relates to a binocular optical device, especially electronic glasses. Background technique [0002] Spectacles or vision aids and spectacle glasses for correcting visual errors or for protection against light, dust, splinters and other kinds have been known for a long time. Most of these vision aids have lenses or prisms that are worn in front of the eyes to correct various visual errors. The most widely used form of eyeglasses consists of a pair of glass lenses supported by a metal or plastic frame and placed on the bridge of the nose. The frames are held in place by hooks (arms) that run sideways around the head or hook behind the ears. Eyeglasses with plastic lenses are commonly used today because the material is less shatterable and lightweight. [0003] The human eye is a photographic eye having a lens device and many visual cells combined into one omentum (retina), and has a spherical structure with a diameter of about 2.5...

AI Technical Summary

Problems solved by technology

[0042] In the above-mentioned prior art, there have been binocular optical devices, electronic glasses and vision aids. The main disadvantage of the above-mentioned optical devices is that the sharpness adjustment of the optical system at the corresponding working distance requires a large mechanical expense and continuous Manually operated and often heavy

Electronic glasses with a microcomputer, rangefinder, and autofocus can meet various requirements as a whole, but it proposes an expensive solution corresponding to the needs

Correspondingly, electronic glasses cannot be widely used, and generally after doing corresponding eye tests, suitable glasses or vision aids are produced for each user
