Instant Vision Assessment Device (IVAD) - George Woo

One minute pitch - George Woo during the World Innovation Day. The award winning Instant Vision Assessment Device (IVAD) is a subjective refraction system. It quickly, accurately and reliably measures refractive errors and anyone can use it with just a short period of training. The World Health Organization’s Vision 2020 initiative inspired Professor George Woo and his team at the School of Optometry to eliminate avoidable blindness by the year 2020. Uncorrected refractive errors, according to the International Agency for the Prevention of Blindness (IAPB) has been a major cause of avoidable blindness. Knowing that many people in developing countries suffer needlessly from impaired vision because of poor access to professional optometrists or ophthalmologists, the team came up with a low-cost, portable solution that is easy to use by trained health or outreach workers.
