Since bifocals were first invented in the late18th hundred , the engineering science behind them has n’t changed too drastically . Now an Israel - based kickoff - up is work on a new type of crystalline lens that apply voguish tech to automatically adjust their centering based on what you ’re looking at , MIT Technology Reviewreports .
The company , calledDeep oculus , has spend the past three years developing their Omnifocals . When people wear upon the glasses are n’t looking at objects up - close , the lens system default to rivet on objects farther forth like a regular pair of glasses . The moment the wearer move their eyes to look at something closer like a book or a phone projection screen , detector built into the frame measuring rod the distance between the pupils and direct the data point to a mini processor . The CPU then uses this info to correct a special liquid state - crystal layer in the lenses so that it refracts lighter consequently .
This eccentric of technology could be especially helpful for with mass with presbyopia , which is the same condition that inspiredBenjamin Franklinto create himself a duo of bifocals . This vision problem unremarkably move people as they get on , making it more hard for them to focus on object that are closer . Many mass with presbyopia fag out eyeglasses with progressive lenses that postulate look through the exact right spot to concentre clearly . These new type of electron lens ego - adjust within afraction of a secondwithout requiring any extra elbow grease from the wearer .
While the eyeglasses are still in the prototype stage , a commercial variant could be coming sometime in the futurity ; the party expects to have people begin to test them " extensively " in about two years , CEO Yariv Haddad toldMIT Technology Review . Deep Optics recently announced that they have $ 4 million in venture uppercase to make their vision a reality , thanks to investors like the French glasses companyEssilor . Besides the monocle industry , the applied science could also be of interest to virtual - reality headset manufacturers looking to make their user less prostrate to move - unwellness .
