Refraction occurs when light passes thru two media of different densities. For example, light passing from air into water. When light passes into the 2nd media it is bent. This causes objects in (for instance) the water to appear in a position different from their 'real' position. This makes it difficult to spear a fish using visual observation only.
The aqueous humor moistens and supplies nutrients to the anterior and posterior chambers of the eye.The vitreous humor also moistens and supplies nutrients to the eye,in addition it serves as a shoke absorber (cushion) that privents the collapse of the eye.thy both helps in refraction of light rays.
Assuming your talking about the eye...it would be the aqueous humor. The aqueous humor is produced by the ciliary processes in the ciliary body. It flows from the ciliary body into the anterior chamber. It travels out through the trabecular meshwork and into the Canal of Schlemm. It is then delivered to the bloodstream via anterior ciliary veins.
The lens and cornea are nourished by the aqueous humor, a clear fluid that provides nutrients and oxygen to these structures. The aqueous humor is produced by the ciliary body and flows through the anterior chamber of the eye. Proper nourishment is essential for maintaining the health and clarity of the lens and cornea.
Aqueous humor and vitreous humor are fluids in the eye that help maintain its shape, provide nutrients, and remove waste. Aqueous humor nourishes the cornea and lens, while vitreous humor supports the retina and helps maintain the eye's structure. Both fluids play a crucial role in keeping the eye healthy and functioning properly.
The fluid in the anterior chamber of the eye is called aqueous humor. It is a clear, watery fluid that is continually produced by the ciliary body and circulates through the anterior chamber before draining out through the trabecular meshwork. Aqueous humor helps maintain intraocular pressure, provides nutrients to the avascular structures of the eye, and removes metabolic waste products. Imbalances in aqueous humor production or drainage can lead to conditions such as glaucoma.
Aqueous humor plays a role in maintaining intraocular pressure and nourishing the avascular structures of the eye, such as the lens and cornea. By circulating through the anterior chamber of the eye, it helps to maintain the shape of the eye and refract light properly onto the retina, leading to a clear image formation.
In general, the process refraction only occurs in the eyes (as far as I know). So I assume you are asking how animals use refraction in their eyes, and by "refraction" you mean the refraction of light. In general, when light enters the eyes, it first enters the cornea of the eyes, which is then refracted into the pupil through the aqueous humor. The thickness and convexity of the lens control how the light is refracted into the eye. The light is focused on the retina which has rods and cone (photoreceptors/light sensors) which sends nerve impulses to the brain. Therefore, the animal is able to see. The parts of the eyes that does the refraction are the cornea, aqueous humor, lens, and the vitreous humor. You might want to surf the web for more details about this

The vitreous humor is thicker and more gel-like compared to the aqueous humor. The vitreous humor helps maintain the shape of the eye and provides support to the retina, while the aqueous humor helps nourish the cornea and lens.

Cornea, aqueous humor, lens, vitreous humor
The vitreous humor fills the space between the retina and lens while the aqueous humor is located between the lens and the cornea.The vitreous humor has more nutritive value when the aqueous humor is low in nutritive value.
Aqueous humor is not to be confused with vitreous humor.I thought 'aqueous humor' meant something that was so funny that it would make tears run down my face!No, aqueous humor is a clear, gelatinous fluid found in the anterior and posterior chambers of the eye, between the cornea and the lens.Oh, so an optic surgeon might tell their surgical nurse to beware the aqueous humor during a particular procedure.
The ciliary body and the choroid plexus within the lateral ventricles of the brain produce the aqueous humor in the eye. The aqueous humor nourishes the cornea and the lens, provides intraocular pressure, and removes waste from the anterior chamber of the eye.
The lens and cornea are nourished by the aqueous humor, a clear fluid that provides nutrients and oxygen to these structures. The aqueous humor is produced by the ciliary body and flows through the anterior chamber of the eye. Proper nourishment is essential for maintaining the health and clarity of the lens and cornea.
The aqueous humor of the eye is reabsorbed into venous blood through the trabecular meshwork and Schlemm's canal. This process helps maintain the appropriate pressure within the eye, known as intraocular pressure. Imbalance in the production and drainage of aqueous humor can lead to conditions like glaucoma.
