True.
Yes the lens focuses the light to the back of the eye, the retina, which has rods and cones. rods-sharpness and grayscale and cones-color.
The lens focuses the light on the retina. If your lenses are too short, the light is focused in front of the retina, making you nearsighted (myopic). If your lenses are too long, the focal point is past the retina, making you farsighted. Most people need reading glasses eventually, even if their eyesight has been perfect, because with age the lens loses flexibility, which means it cannot shorten to accomodate close vision, so glasses are needed to correct this.
Rods
To strengthen your retina, you can ensure you have a healthy diet rich in antioxidants, particularly vitamins A, C, and E. Protect your eyes from harmful UV rays by wearing sunglasses outdoors. Regular eye exams can help detect any issues early on and allow for prompt treatment. Engaging in eye exercises, such as focusing exercises or eye yoga, may also help improve retina health.
The microscope stage is the platform where the specimen being observed is placed. Its main function is to hold the specimen steady and allow for precise positioning and movement so that specific areas can be viewed under the magnifying lenses of the microscope. The stage typically has controls for adjusting the position of the specimen to focus and examine it effectively.
When bending light rays to focus them on the retina the two structure involved are the air-cornea interface which accounts for about two-thirds of the light-bending process and the lens which accounts for the remaining third but also makes the necessary adjustments to allow the eye to focus on objects at different distances.
These nerve cells are called rods.
Light travels through the pupil to the cones, which lie on the inside of the eye. It is these photoreceptors that allow the perception of color.

The fine and coarse focus knobs allow you to adjust the focus of the microscope. The coarse focus knob helps to bring the sample into approximate focus, while the fine focus knob allows for precise focusing.
