Hint: The lens is located in the eye. By changing its shape, the lens changes the focal distance of the eye. In other words, it focuses the light rays that pass through it (and onto the retina) in order to create clear images of objects that are positioned at various distances. It also works together.
Complete answer:
Eye lenses: The behind the iris is the focal point. By changing its shape, the focal point shines light on the retina. Through the activity of small muscles (called ciliary muscles), where the object is closed, the focus becomes thicker, starting from zero, while away from the object, the focus becomes thinner, starting from zero. The retina contains cells that sense light (photoreceptor cells) and veins that maintain them. The most sensitive part of the retina is a small area called the macula, which contains a large number of firmly filled photoreceptors (called cones).
The most sensitive part of the retina is a small area called the macula, which contains a large number of firmly filled photoreceptors (called cones). The high thickness of the cones in the macula makes the visual image gritty, just like a high-target high-end camera has more megapixels, and each photoreceptor is connected to a nerve fiber. The nerve filaments from the photoreceptor are packed together to build the optic nerve. The initial part of the optic nerve circle is located behind the eye.
Hence the correct answer is OPTION(D)
Note: Therefore, the refractive power of the lens is a function of the curvature of the lens surface and the refractive index of the cell mass. Tightly arranged, highly ordered lens cell arrays are essential for optical quality and even minor defects. The anatomical structure of lens fiber cells can cause detectable spherical aberration.
