He became interested in the emerging area of adaptive optics in the mid-1980s. After considering the way our eye-brain adaptive optical system works, he suggested that self-refraction with suitable adaptive lens eyeglasses could be a useful procedure for correcting refractive error, after trying such a procedure on himself. He created several prototypes of self-adjustable eyeglasses – including the Adspecs, the world’s first fluid-filled universal eyeglasses – and he carried out research supported by the UK’s DFID which showed that self-refraction with such glasses was a useful procedure for bringing vision correction to around half of the world’s population which currently needs, but does not have, corrective eyewear. The self-refraction procedure is particularly useful for populations where there are too few eyecare professionals to meet the needs of the people. Josh hopes to see a billion people having vision correction by the year 2020.
