You always seem that rabbit eyes get opening constantly. These kinds of small animals never blink their eyes. But, lagomorphs do open and close their eyes occasionally; not like as often as humans. Now, one question is arising in bunny owners that ‘Do rabbits blink their eye or not?‘ If yes, then how many time do this.
Rabbits blink their eyelids so little. Rabbits can only blink 10 to 11 times an hour. You may can’t see it, because rabbits consist a nictating membrane (Third Eyelid), at the front of cornea. This is transparent that helps to keep a rabbit’s eyes moist, wind up the need to blink.
Through this article, you will get all answer of questions about rabbits blinking. Why do rabbits blink less frequently? How often do rabbits blink? And other interesting facts. So keep reading it!!
Rabbit Eye Anatomy and Physiology
Rabbit eyes have uniquely adaptation to their environment. They are positioned on the sides of their heads for a wide field of vision, so easily can detect predators. Apposite to human eyes, rabbit eyes have a capable to optimize for motion detection instead of detailed focus.
One of the most unique features of rabbit eyes is the presence of a third eyelid. This translucent membrane sweeps across the eye from the inside corner that provides the protection and maintaining moisture. The upper eyelid moves so little as compared to humans, because third eyelid takes on many protective and cleansing roles.
The combination of these features support rabbits to keep a vigilant watch for danger, and also ensures that their eyes remain clean and hydrated. With adapting of this unique anatomy, they can easily survive and thrive in their natural habitats.
Do Rabbits Blink Their Eyes? If Yes! Why
Yes! Rabbits can blink their eyes, but they do so infrequently than humans. The primary reason for their little blinking is the presence of third eyelid (Nictitating Membrane) that sweeps across the eye to give protection and keep moisture.

This membrane does many activities typically associated with blinking, such as cleaning the eye surface and distributing tear film. So, rabbits don’t need to full eyelid closure. Rabbits blink offers the protection their eyes from debris, irritants.
Although, the nictitating membrane manages most of these tasks, occasional full blinks are still necessary for extra cleaning and optimal eye health. Rabbits always stay alert for predators by helping of this specialized adaptation.
Do Rabbits Have Eyelids?
Of Course! Bunnies have eyelids. They consist both upper and lower eyelids as similar of human beings. Besides of this, rabbits have also a third eyelid (nictitating membrane). Many animals have this distinctive feature, bunny is one of them.
This nictitating membrane acts as translucent layer that moves horizontally across the eye. Third eyelid serves the protection and maintaining moisture without getting any obstructs the rabbit’s vision.
The upper and lower eyelids in rabbits do close the eye completely when it is necessary. But, they do so infrequently as compared to humans.
Rabbit Third Eyelid Problems
At the rarely, third eyelid can get problems that can affect a rabbit’s overall eye health and vision. There are some common issues related to the rabbit’s third eyelid include:

Prolapsed Nictitating Membrane
A prolapsed third eyelid, often called the “Cherry Eye.” It occurs when the membrane becomes visible and protrudes over the eye. This can causes of the inflammation, injury, or underlying health issues. A prolapsed third eyelid can experience the irritate the eye. Now, you have to require veterinary attention to address the underlying cause and reduce the inflammation.
Infection and Inflammation
The third eyelid can become infected or inflamed due to bacterial, viral, or fungal infections. Several symptoms of infection can be exhibited like as redness, swelling, discharge, and excessive tearing. If, you suspect any infection, then visit your veterinarian.
Tear Duct Obstruction
The nictitating membrane supports to distribute tears across the eye. But, third eyelid also becomes more prominent that tear duct obstructions. If, their tears get blockage, then may lead to excessive tearing, discharge, and secondary infections. In their treatment, you may involve flushing the tear ducts and addressing the reasons of the blockage.
Dry Eye
If, eyes do not produce enough tears, then they get dryness and irritation. The third eyelid does become more visible, because the rabbit tries to compensate for the lack of moisture. Treatment typically includes artificial tears and addressing any underlying health issues contributing to the dry eye condition.
Tumors
Get injury on the third eyelid can cause conjunctival flaps and free margin. Careful suturing as soon as possible after the traumatic event can prevent deformation and shortening of the nictitans.
Health Benefits of Rabbits Blinking Their Eyes
Here, you will get essential health benefits of rabbits blinking their eyes, including:
Moisture Distribution
- Keeps the cornea moist by spreading tear film
- It helps to prevent the dryness and maintains eye health.
Protection from Debris and Irritants
- Removes dust, dirt, and foreign particles.
- Helping to prevents scratches, infections, and potential injuries
Lubrication
- Reduces friction between the eyelid and eye surface
- Keep away to discomfort and potential damage from dryness.
Nutrient Supply
- Delivers essential nutrients and oxygen to corneal cells
- Helps to supports cell health and repair processes.
Removal of Waste Products
- Flushes out metabolic waste products from the eye surface
- Maintains a healthy environment for corneal and conjunctival cells
Prevention of Infections
- Spreads antimicrobial properties of tears across the eye
- Remove the risk of bacterial, viral, and fungal infections.
Healing and Recovery
- Accelerates healing of minor injuries and irritation
- Serve the nutrients and protective agents for quicker recovery.
Stress Reduction for the Eyes
- Ensures consistent moisture and lubrication
- Reduces overall strain and stress on the eyes
How Can You Train Rabbits to Blink Their Eyes?
Training rabbits to blink their eyes voluntarily isn’t feasible, as blinking is an involuntary reflex. However, you can promote eye health to support their natural blinking reflex. Here’s how:
Environmental Cleanliness: Keep their living area clean to minimize dust and debris. It can irritate their eyes.
Balanced Diet: Provide a diet rich in hay and fresh vegetables to support eye health.
Regular Health Checks: Monitor their eyes for any signs of redness, discharge, or swelling. Make schedule regular veterinary check-ups.
Stress Reduction: Provide a calm environment and handle them gently to minimize stress. It can impact their overall well-being.
Regular Grooming: Groom them regularly to prevent fur from irritating their eyes.
Preventive Care: Use dust-free bedding. Ensure their play area is hazard-free to prevent eye injuries.
Eye Care Products: Consult a vet about using artificial tears or saline eye rinses to maintain eye moisture and cleanliness if needed.
Facts about Rabbits Blinking Their Eyes
There are some fascinating facts about rabbits blinking their eyes:

Infrequent Blinking: Rabbits blink much less frequently than humans. They blink only 10 to 12 times per hour, but humans can blink 15 to 20 times per minute.
Nictitating Membrane: Rabbits have a third eyelid called the nictitating membrane. This helps to keep their eyes moist and shields them from dust and debris.
Unique Eye Structure: Rabbits consist four lacrimal glands. One of them produces an oily substance that helps to tears stay stable and reduces evaporation. They also have only one lacrimal duct opening that allows more tears to remain in the eye.
Sleeping with Eyes Open: Rabbits can sleep with their eyes open due to the nictitating membrane, which helps them stay alert even while sleeping. Due to this, bunnies can easily detect predators.
Rapid Blinking: If a rabbit is blinking rapidly, get an eye problem, such as infection or corneal ulcer. It is essential to check for foreign objects or debris in the eye and consult a veterinarian if the blinking persists.
Prey Animals: Rabbits are prey animals that have evolved to detect and evade predators. Their large eyes, sharp hearing, and ability to see in a 360-degree view help them stay alert and avoid danger.
Depth Perception: Rabbits have limited depth perception due to their eye structure. But, with using of technique (parallaxing); they can determine the distance and size of objects.
Color Vision: Rabbits are not completely color blind but can only see blue and green light. They do not have any receptors that can detect red light. So, these wavelengths appear as greyscale or shades of blue and green.
