The 3 major parts of the eye are the Iris, the Lens, and the Retina.

The iris regulates the amount of light let into the eye. The lens focuses the incoming light onto the retina. The retina at the back of the eye senses the presence, intensity, and frequencies (colors) of the light, and sends those senses via two optical nerves to the lower rear of the brain for interpretation.

Why is it necessary to be able to focus at different depths using a compound light microscope?

Focusing at different depths with a compound light microscope is essential for obtaining a clear, detailed view of specimens at various layers or structures. Different parts of a sample may reside at different focal planes, and adjusting the focus allows for the visualization of specific features, such as cell layers or internal structures. This capability enhances the overall understanding of the specimen's morphology and function, facilitating more accurate observations and analyses. Additionally, it helps in minimizing distortions that can occur when viewing three-dimensional objects in a two-dimensional plane.
