what is the nature of the eye lens and what does the eye lens do? In human eye
Answers
Light rays converge on the retina after passing through the lens of your eye because it is convex. The image forms upside down on the retina because no object can be closer than the focal point ( F ) of your eye lens. All objects placed beyond F will produce inverted, real images (for convex).
In the eye, the lens is held in place by tiny ligaments connected to the ciliary muscles. These muscles control the level of tension in the ligaments and therefore control the shape of the lens. When the eye is relaxed, tension in the ligaments causes the lens to be slightly flattened. When the eye focuses on a nearby object, the ciliary muscles contract, to reduce the tension in the ligaments and cause the lens to become more spherical. As the lens changes shape, it causes the light that passes through it to focus at a different location. This is called accommodation and is what allows your eyes to focus on both near and far objects. By contracting or relaxing the ciliary muscles, you can cause your eyes to focus on an object that is any distance away.
======= Answer =========
• Nature of the human eye is converging as they are convex lenses...
What do they do..??
They converge the light emit on them and just draw the direct image to the focal length...
They also joint the eye to the ciliary muscles to connect with brain signals....
They are just important to have vision of sight and to see...
Thank you
