"The cornea is like a window and allows light to pass through to the retina, which is located at the reverse side of the eye. Light rays are refracted by the cornea, focused by the lens and then projected onto the retina, forming an image which is then transmitted to the brain."
"The Cornea is like a crystal covering a clock face. It is a clear round dome covering the iris, the colored ring in the center of the eye, and the pupil, the black circle in the middle of the iris. The cornea plays an important role in vision by helping to focus light as it enters the eye."
"If an eye is looking straight upward, the cornea is like a dome shaped roof that continues right down to the floor."
"The Cornea is like the windshield of a car. It is a clear round dome covering the iris and the pupil, protecting the internal structures from damage."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
