The image formed on the retina is smaller than the object but inverted. The eye’s lens projects a reduced, upside-down image onto the retina. The brain then processes this information, correcting the inversion and enabling us to perceive the image ...
The part of the eye that controls the amount of light entering the eye is the iris. The iris adjusts the size of the pupil, regulating the light that reaches the retina, thereby ensuring optimal lighting conditions for vision in ...
In eye donation, the part of the donor’s eye that is transplanted is the cornea. The cornea is the clear, dome-shaped surface that covers the front of the eye and helps focus light onto the retina. Corneal transplants can restore ...
Light waves are converted into nerve impulses in the retina. The retina contains photoreceptor cells (rods and cones) that detect light and convert it into electrical signals. These signals are then transmitted to the brain via the optic nerve, where ...
