Cats are adorable little animals, and their eyes seem to possess a magical power that captivates people at first glance. But have you ever wondered what exactly is inside a cat's eye? Actually, there is a transparent viscous substance inside a cat's eye.

1. Structure of a Cat's Eye

A cat's eye is a black round shape composed of three layers: the eye surface layer, the inner eye layer, which contains a layer of viscous substance, and the back eye layer. The eye surface layer includes the cornea, iris, lens, and ciliary body, with the ciliary body being the focus of the eye. The inner eye layer consists of the vitreous body, choroid, and iris sac, among which the choroid is a transparent viscous layer that protects the eyeball from external damage. The back eye layer is composed of the choroid and vascular tissue within the choroid.

2. Function of a Cat's Eye

The structure of a cat's eye allows it to perform visual functions, capturing light to see the surrounding environment. The transparent viscous substance protects the eyeball from external harm and keeps the eye moist, maintaining eye health.

3. Characteristics of a Cat's Eye

The characteristic of a cat's eye is that its color is deeper than a human's eye, enabling it to better capture light and have superior visual effects. Additionally, cats have relatively larger eyes in proportion to their body size, resulting in better vision compared to other animals.

4. Protection of a Cat's Eye

Protecting a cat's eyes is important and can be done in several ways: first, regularly washing their eyes to keep them clean; second, providing them with a balanced diet to improve eye health; third, avoiding prolonged exposure to intense light to prevent eye damage.

5. Examination of a Cat's Eye

To ensure the health of a cat's eyes, regular examinations should be conducted to check for any injury or infection. If any abnormalities are found, timely medical attention should be sought to maintain healthy eyes.

In summary, there is a transparent viscous substance in a cat's eye that not only protects the eyeball from external damage but also keeps the eye moist to ensure visual performance. At the same time, we should strengthen the protection of cats' eyes and regularly check to ensure their eye health.
