In which structures does light travel after passing through the cornea?

1. Aqueous humor, retina, lens, vitreous humor

2. Aqueous humor, lens, vitreous humor, retina

3. Retina, lens, aqueous humor, cornea

4. Lens, cornea, vitreous humor, retina

The correct answer is: Aqueous humor, lens, vitreous humor, retina

After light passes through the cornea, it encounters several critical structures of the eye that contribute to vision. The correct sequence following the cornea begins with the aqueous humor, the clear fluid located in the anterior chamber of the eye, which the light travels through to reach the lens. The lens is a transparent structure that further refines the focus of the incoming light before it passes into the vitreous humor, a gel-like substance that fills the main cavity of the eye and maintains its shape. Finally, the light reaches the retina, where photoreceptor cells convert the light signals into neural signals, which are then processed by the brain to create images. This pathway is essential for forming a clear image on the retina for visual perception. The other choices, while they might mention some of these structures, do not follow the correct order in which light travels after it passes through the cornea, which is crucial for understanding the anatomy of the eye and the visual process.
