A pair of lovely twin cats, which has heterochromatic eyes, are currently gaining thousands of followers on Instagram.

In an article written by Vaiva Vareikaite of Bored Panda, it was disclosed that two white cats, Iriss and Abyss, are now being called as the most beautiful twin cats in the world because of their extraordinary looks. The inseparable cats both have heterochromatic eyes.

Having heterochromatic eyes means that eyes are of different colour. For example, one might be green or brown and the other blue, or there might be a few colors in one eye. Other terms to describe different colored eyes are heterochromia iridis and heterochromia iridum. “Iridis” and “iridum” which refers to the iris of the eye. The iris is the thin, circular structure that surrounds the pupil and contains the pigment melanin, which gives our eyes their distinctive color.

Heterochromia usually is benign; it is not an eye disease, and it does not affect visual acuity.

Types Of Heterochromia

There are three types of heterochromia, based on where the different colors are located, as disclosed by All About Vision:

1. Complete heterochromia — This is where the iris of one eye is a completely different color than the iris of the other eye.

2. Partial heterochromia (or sectoral heterochromia) — This is where only a portion (or sector) of the iris of one eye has a different color than the rest of the iris of that eye. Partial heterochromia can occur in one eye or both eyes.

3. Central heterochromia. — In this type of heterochromia, the iris has a different color near the border of the pupil (compared with the color of the rest of the iris), with spikes of the central color radiating from the pupil toward the middle of the iris.
