      Hi @dilan123,

      vision is achieved by your lens focussing light very precisely onto the retina (the sheet of cells at the back of your eye). Children tend to be long sighted as the lens focusses light incorrectly after it hits the retina, however as you grow this corrects itself as the eye gets bigger and the light that was once focussing behind the retina, now focusses on the retina.
