Why do we have to bring a small object near the eyes inorder to see it clearly?
Answers
Answer:
When the eye focuses on near objects the eye must accomodate to see object clearly because ciliary muscles contract which releases tension on the ligament that suspend the eye. As a result both lenses surfaces become more curved and the eye thus focuses on nearby objects clearly.
Answer:
This is a simple diagram that shows how the ciliary muscles inside your eyes contract and relax to change the shape of the lens. When looking at an object that is far away, the muscles relax and the lens is flatter. This allows the light rays to converge and focus on your retina.
If you notice the lens in the second picture, the muscles are contracted and it bulges out. This shape causes the light rays which are diverged to converge on the retina.
When an object is placed too close to your face the lens is not able to form a shape that allows the light rays to properly focus on the retina. This causes the image you see to look blurry. With age, it becomes difficult for
the lens to make these changes and for the muscles to contract and relax. This leads to a condition known as presbyopia. Near vision, such as reading and writing, is affected while distance vision is the same.
