Professor JOSHUA SLIVER TED TALK : Atlanta 2015

Joshua Silver is an atomic physicist and Professor of Physics at the University of Oxford. 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, Silver 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 adaptive lens eyeglasses, and then carried out research supported by the UK’s DFID which

showed self-refraction with adaptive eye wear to be a useful procedure for bringing vision correction to around half the world’s population which currently needs, but does not have, corrective eye wear. The self-refraction procedure is particularly useful for populations where there are too few eye care professionals to meet the needs of the people. Silver now directs the Centre for Vision in the Developing World, and hopes to see a billion people having vision correction by the year 2020. AdSpecs: Helping the Billion in Need

One Mission:

Professor Silver and the Centre have an ambitious vision for the future - one billion people to get the glasses they need but lack access to by 2020. TED TALK : Atlanta 2015


How Does it Work? Lens Mounting Flexible Plastic Membrane

Fluid Pumped In

Power of Lens Increase Suitable for long-sightedness (hyperopia) and loss of accommodation (presbyopia)

Transparent Fluid Reservoir

Fluid Pumped Out

Power of Lens Reduced Suitable for shortsightedness (myopia)

CHILDREN AND THEIR LEARNING SKILLS. 25%

15-25% of children have vision problems, many of which are undetected.

TED TALK : Atlanta 2015

80%

Approximately 80% of a student’s learning is done visually.

60%

60% of kids with learning problems have undiagnosed vision problems

70%

At least 70% US juvenile delinquent population has vision problems


Information

An estimated 19 million children are visually impaired.

Of these, 12 million childrean can be cured simply by wearing glasses.

80%

1.4 million are irreversibly blind for the rest of their lives due to the lack of treament provided.

Problem: The major problem to overcome is a lack of personnel to fit them. Highly trained optometrists are very rare in many parts of the developing world, and often leave to work in countries where their skills will bring them better pay. Soultion: To really tackle this problem, we need to get to the stage where the cost of the pair of glasses is not prohibitive to the more than 1 billion people living TED TALK : Atlanta 2015

on less than a dollar a day. To do this many things must happen, but the key is investment and engineering on a truly flexible, innovative low-cost design for self-adjustable glasses made for the developing world. So by donating any amount can help us reach our goal of ONE dollar selfadjustable glasses faster.
