Question

What is the lens of the eye ?

Answer 1

Hint:Here, you are asked about the lens which is located in our eyes. In order to answer this question, what you need to do is first consider the basic structure and components of an eye and also use the definition of a lens and the basic function of a lens, meaning what is the purpose of a lens.

Complete answer:
We see through our eyes and all the optical instruments are primarily used in order to act as an assistance of our eye to view objects. Eye works on a particular mechanism and it has a number of components. The shape of an eye is nearly spherical and the diameter of the eye is approximately an inch.

The front portion of the eye is sharply curved and is covered by cornea. Cornea is a transparent protective membrane. Behind the cornea, we have aqueous humor which is a liquid and behind that we have a lens of the eye. The space between the eye and cornea is filled with the liquid mentioned above.

The lens of the eye is a transparent biconvex structure which helps the light to refract and then get focused on the retina. The shape of the lens changes in order to change the focal length of the eye according to the distances of the objects from the eye so that a sharp image of that particular object of interest is formed on the retina.

Note:We have discussed in brief about the basic structure and components of the eye and all the things discussed should be kept in mind. Also remember that the first cover is known as cornea, after that we have a liquid called aqueous humor and finally after the liquid, we have lens of the eye. The lens’s main function is to change shape focus light so that the image is formed on the retina.
