The team from the London School of Hygiene and Tropical Medicine said that the applications on your smartphone or smartphone can be effective in testing eyesight as is done in the clinic optometrist.
The conclusion obtained from tests on 233 people in Kenya. And the result, as published in JAMA Ophthalmology showed that mobile phones can provide similar results as well as eye diagrams.
Tim from London along with their colleagues in Scotland modify the smart phone in order to develop a series of vision tests that can be used, with just a little training and is easy to carry around.

The price for this phone is relatively cheap, at about 300 pounds. Compare this with the eye examination apparatus is quite large with a cost of 100 thousand pounds sterling.
