6 Times Enlarged Human Eye Model is a biology teaching tool used to demonstrate in detail the structure and function of the human eye. This model is usually made by magnifying the actual proportion of the human eye by 6 times, so that students can observe the various components of the eye more clearly, such as the cornea, iris, lens, retina, and optic nerve. In biology teaching, enlarging the eye model can help students intuitively understand the anatomical structure of the eye, learn the process of visual formation, including how light is focused on the retina through the cornea and lens, and how the retina converts light signals into neural signals and transmits them to the brain.
