Which jelly-like substance maintains eye shape and optical properties?

Which jelly-like substance maintains eye shape and optical properties?

• A. Aqueous humor
• B. Choroid
• C. Vitreous humor
• D. Cornea

Answer: (C)

Vitreous humor is the gel-like substance filling the large cavity behind the lens. Its jelly consistency helps keep the eyeball properly inflated, preserving shape, and provides a clear medium through which light travels to reach the retina, supporting accurate optical transmission. Aqueous humor is a watery fluid in the front and middle chambers that nourishes tissues and maintains pressure but isn’t jelly-like. The choroid is a vascular layer that nourishes the retina, not a gel filling. The cornea is the transparent front surface that refracts light and protects the eye, but it isn’t a jelly-like internal filling.
