Health conditions also have a great influence on the eye color of mature rabbits, as my bunny’s eye color changes when it is suffering from fever or any other health-related problems.

Additionally, genetic factors lead to a permanent change when they are at developing stages but rarely affect the mature rabbits in case of mutation.

Furthermore, the concentration of melanin in the iris also control it. Once the concentration of melanin reaches a limit required to maintain the color at maturity, their eye color does not change afterward.

Why do rabbits change their eye color?

The transition in eye color is possible after reaching maturity due to infection, injury or illness, glaucoma, or any other health problem. These changes can be treated using proper medication and appropriate care, but some changes are gradual and do not require any consultation from the vet.

Cataracts in rabbits occur in different ways and the eye color changes depending upon the progression and severity of cataracts.

In many cases, it does not lead to a visible change in the color of the lens but causes opacity or cloudiness in the eyes, making them hazy. It also turns into bluish or greyish due to increased cloudiness.

However, secondary complications usually arise if it is severe, like inflammation or a change in the appearance of the affected area.

In the advanced stages of this condition, it darkens and turns into a reddish hue. It is essential to thoroughly examine the condition for accurate diagnosis of cataracts and appropriate treatment.

2-Diseases

Some diseases cause red or pink eyes in rabbits, like systemic diseases, e.g., myxomatosis or pasteurellosis (snuffles). These have effects on the eyes and other multiple organs.

It leads to redness in the eyes along with some other ocular symptoms. In addition, there is another condition in which the uvea gets inflamed, called uveitis.

It is caused by autoimmune diseases, trauma, health problems, and other infections in eyes. It sometimes leads to sensitivity to light, redness, blurred vision, or pain.

Furthermore, exposure of your bunny to irritants like chemicals, smoke, or dust particles can cause redness or irritation. Environmental factors and bedding material can particularly cause allergies in the eyes.

3-Infections

The infections cause temporary changes in the color of rabbits’ eyes, either directly or indirectly. Bacterial conjunctivitis affects the thin membrane (conjunctiva) covering the eye’s white part and the eyelids’ surface.

In conjunctivitis, this membrane gets swollen or appears red and produces pus that becomes visible in the eyes. It leads to changes in their appearance or color in severe cases.

Further, dacryocystitis is an inflammation of tear ducts that leads to a change in the lens color when it gets chronic. In chronic situations, the tear ducts get scarred or damaged.

A few other examples of infections responsible for changes in eye color include viral conjunctivitis, chlamydiosis (bacterial infection), and encephalitozoonosis (a parasitic infection).

4- Glaucoma or corneal edema

Glaucoma is not directly involved in changing eye color in rabbits. It is characterized by increased pressure, which causes damage to the optic nerve.

Increased pressure in the eyes makes the cornea hazy or cloudy and changes appearance. Furthermore, this condition leads to cataracts with excessive tearing and squinting in some cases.

Corneal edema is associated with fluid accumulation within the cornea, leading to swelling. Their eyes become hazy or cloudy, which affects their overall appearance or color.

The iris color does not get affected by edema, which mainly determines the shade of the eyes. Other reasons for corneal edema can be infections, injury, medications, or underlying health conditions.
