Question

A scientist was working on creating a model of the human eye. He created an alternative for every part of the eye. However, he placed a rigid lens in the place of the eye lens before packing the model into an eyeball. What would be the problem with this eyeball?

• A. The model cannot capture an image of any object.
• B. The model can capture images of objects at certain locations only.
• C. The model will crumble.
• D. There will be no problem with the model.

Answer 1

The correct option is B The model can capture images of objects at certain locations only.

The lens of the human eye coverges the incident rays to the retina. In order to see every object clearly, all the rays must be converged onto the retina. This means that the lens must be able to reshape itself so that at any instant, it could converge the rays onto the retina.
In the model of the eye, the lens is rigid, which means it cannot change its shape. Thus, the model can capture images of objects that are at certain locations only.
