In the United Kingdom, it's alarming just how many people have never been to get their eyes tested, with a high percentage of those who have having never been since their school days. Given just how valuable our eyes our to the way we live, it's surprising how many people have never been tested, particularly considering how many life threatening illnesses can be diagnosed early on by an optician's test.

Perhaps the reason a lot of people don't go for tests is because it's a hassle, or because they're concerned about exactly what an eye test entails. This level of concern is no longer necessary though, as now you can not only get an eye test through your mobile phone, but even use the app to find out your prescription.

The application comes from the team at MIT Media Lab, who have found a way to bring eye testing to anyone, anywhere. The application works via a small plastic device which is clipped to your phone, acting as a lens through which to view the phone screen. You then look down through the lens at your phone's screen and take part in the test via your phone's arrow keys.

The whole test is complete in under two minutes and will not only reveal whether or not you need glasses, but will also tell you the level of prescription glasses you need. This could be extremely useful if you don't want to take a trip to the high street, as you can test your eyes, find your prescription and purchase your prescription sunglasses without even leaving your home.

The application was originally developed to help those in developing countries take proper care of their eyes, particularly in countries where opticians either aren't available or cannot be reached.

If you're looking to find out more information about the app you can simply search for the phrase 'MIT Optometry App', which will not only reveal a huge amount of information about the application but will also show you how to use the app and where you can find it. If you are worried about your vision and you're unable or unwilling to make it to an opticians, this application could be just what you need to put your mind at rest, instead of just putting on your sunglasses and not worrying about it.
