To understand how we see the world, it is necessary to comprehend the complex structure of the human eye. The light that enters the eye goes through several layers and structures before being converted into an image that the brain can interpret. Consider the following excerpt from a poem: 'The light of the stars crosses the darkness, travels through space, and gently lands in my eyes, where small miracles transform it into vision.' (Unknown author). Based on your knowledge, describe the path that light travels from entering the eye until the 'image' is formed on the retina, and explain the role of at least two eye structures (such as the iris, the lens, or the cornea) in the process of light focusing. Then, relate this process to the importance of vision for human daily activities.
