Lens focuses light rays on the retina.

Further Explanation:

The eye is the sensory organ of the organism that allows it to see the object.

The eye consist of various part:

1. Sclera-Outer covering of the eyeball is tough and has white layer called as sclera

2. Cornea-The light enters the eye through it. It is the curved layer in front of iris and pupil.

3. Pupil-It controls the amount of light entering into the eye

4. Iris-it surrounds the pupil and regulates the amount of light passing into the eyes.

5. Lens-It sits behind the iris. It focusses light onto the retina.

6. Retina-It comprises of photoreceptors and blood vessel that nourishes the former. The two main types of photoreceptor:

a. Rods: It is responsible for night vision and are more sensitive to light.

b. Cones: It is responsible for color vision.

The eyeball is basically divided into two regions which are filled by the fluid. The two type of fluid found are

1. Aqueous humor: Is present across the space separating cornea and the lens.

2. Vitreous humor: Is present across the space separating the lens and the retina.

Law Incorporation [45]

The bony labyrinth is a region of dense bone that surrounds and protects the membranous labyrinth.

Labyrinth is the name given to the inner ear. It is made up of a network of interconnecting sacs and canals. The inner ear is composed of two parts: bony labyrinth and membranous labyrinth. A vestibule, three semicircular canals, and a spirally wound cochlea make up the bony labyrinth. It is perilymph-filled.

The membranous labyrinth is encircled by the bony labyrinth. It includes the hearing and balance sensory receptors. The cochlear duct, saccule, and utricle and three semicircular ducts that make up the endolymph-filled membranous labyrinth. The cristae, an organ of corti, and the ampullaris maculae are examples of sensory receptors.
