Eye seems to be very small organ of our eye but, it's one of the most complicated one.
We all know we understand think while see. Hearing is another special sense but, we can't understand how one thing is just by hearing the distribution but if you one see an object even without describing ... That is the power of sight and how that influence our brain to signal ...
We should always take care of our eye, don't be stupid and neglect any problem of your eye. Consult a doctor and take appropriate treatment....
Nothing can replace the GOD's gift which define yourself...No technology has developed yet and nothing can cross his perfection ....
