Future Uses Of The Mobile Phone

I have always been fascinated with mobile phones and in 40 years there  have been aome amazing changes.   I have one mobile phone in my collection that weighs in at 4.7 kilos, it took 10 charge and you could speak for 30 minutes.  So what is the future of mobile phones, what we had then and what we have now.  

It just hi-lites the wonder of the future of these devices.  Sending a text is one thing, playing games, sorting out your finances is another?  But using a mobile phone whereby Aid workers using this application can do eye tests quickly and inexpensively out in remote and developing areas was to good a story not to write about.

Researchers at the MIT University in the US have developed a software application and a plastic lens type device to fit to the phone so to be able to undertake low cost eye exams.  As in the photo, the plastic lens piece is clipped onto the phones lens, the patient looks into the lens, and presses the phone's arrow keys until sets of parallel green and red lines just overlap.  This is repeated eight times, with the lines at different angles, for each eye.

The whole process only takes two minutes, at which point the software loaded onto the phone then provides the prescription data.
