For a normal human eye, the range of vision describes the range of distance for which human eyes can see an object clearly. For a person to see an object with a clear vision, the image of that object must fall accurately on the retina. This means that the distance of image must be equivalent to that of lens-to retina distance. But, the lens-to-retina distance remains fixed, therefore the image distance is always the same for all objects at all distances. Our eyes manage to do this by adjusting the power of their lenses. This process of adjustment is known as accommodation and it is done by changing the shape of the lens of our eyes.
