Contact lenses or glasses can easily correct these simple visual aberrations. But these aberrations cannot be found that easy, hence the Doctor assistance is necessary.

This paper is designed in such a way that people can use this application handy, thereby avoiding frequently consulting the Doctor. This application will be very useful in places like villages, where in eye hospitals are scarce moreover it can be used by everyone who know just basic English language. It is presented in easy and understandable format. This application proposes a test based on the Snellen’s chart, where the viewers are asked to keep the mobile at a particular distance(30cm- varies with mobiles) and were asked to look carefully to a letter of Snellen and gradually keep decreasing step by step, until the viewer is not able to distinguish the characters of Snellen’s chart. It gives an accurate result of eye power by calculations using logMAR. This application also helps users with testing colour blindness that is they can make difference ion colours which have similar pattern or texture, redness test and data on various eye diseases with symptoms and remedies. Regular check-up using this application provides a graph representation of the previous records that help users to know their level of improvement which can be sent to any particular ophthalmologist of a hospital (like Vasan eye care) through mail.
