This is the idea in which we can analyse our eye power by our own android device. In this idea we use the sensors and the device which are used by the eye specialist. The main device which is used by the eye specialist auto refractor. The project makes the auto refractor machine in to small integrated part by using the instrumentation and control concepts and MATLAB concepts. We can make the auto refractor inbuilt in the android phone as small equipment and by using the camera module in the phone we can make our eye to focus in the camera and then the device which is inbuilt in the android sense our eye power exactly and the power of our eyes (short sight or long sight or nil power)and it functions by getting our eye biometric scan, the analyses is done here.
