Leopard Gecko Keeping One or Both Eyes Closed: Causes & What to Do

Leopard geckos have movable eyelids, so they may briefly close their eyes while resting. But if your gecko keeps one eye shut for long periods, squints repeatedly, or closes both eyes while awake, that usually points to discomfort. One of the most common causes is retained shed around the eyelids. In leopard geckos, poor sheds are often linked to dehydration, low-humidity shedding support, illness, or nutrition problems. Retained skin around the eye can trigger conjunctivitis, keratitis, and secondary infection.

Another common cause is irritation or trauma. Loose particulate substrate, dried debris, feeder insect bites, rubbing, or a scratch on the cornea can all make a gecko hold the eye closed. A scratched cornea can be very painful even when the eye looks only mildly abnormal at first. Swelling, cloudiness, discharge, or repeated licking at the eye raise concern for an ulcer or infection.

Infection and inflammation are also possible. Bacteria may infect irritated tissue, and reptiles can develop firm abscesses around the eye or behind it. Insectivorous reptiles can also develop hypovitaminosis A when the diet and supplements do not provide enough preformed vitamin A. Merck notes that vitamin A deficiency affects ocular tissues and can cause blepharedema, squamous metaplasia, and other eye changes. In practice, that can look like swollen lids, debris buildup, repeated bad sheds, and eyes staying closed.

Less commonly, a gecko may close the eyes because of more generalized illness, severe dehydration, pain elsewhere, or poor enclosure conditions such as incorrect temperatures, irritating cleaners, or smoke exposure. If the problem lasts more than a day, happens after a shed, or comes with appetite loss, treat it as a medical issue and have your vet examine your gecko.

A brief eye closure during sleep or a single short squint after waking may not be an emergency. If your gecko opens the eye normally within a few hours, is active, hunts well, and there is no swelling, discharge, or stuck shed, you can monitor closely the same day while checking husbandry. Make sure the enclosure temperatures are appropriate, fresh water is available, and there is a proper humid hide to support shedding.

That said, most persistent eye closure deserves prompt veterinary attention. See your vet the same day or within 24 hours if the eye stays closed, looks swollen, has discharge, appears cloudy, or your gecko seems painful. Also go promptly if your gecko is missing prey, losing weight, rubbing the face, keeping both eyes closed, or recently had a bad shed. Leopard geckos rely heavily on vision to hunt, so even one painful eye can quickly lead to poor intake and decline.

Treat this as more urgent if there was known trauma, a feeder insect bite, visible debris you cannot safely flush away, or a sunken appearance suggesting dehydration. Eye ulcers and infections can worsen fast. Waiting too long can turn a manageable problem into a deeper infection, scarring, or permanent vision loss.

Home monitoring is not the right plan if you are tempted to peel off shed from the eyelids, use leftover pet medication, or try human eye products. Those steps can make the injury worse. When in doubt, an exotic animal appointment is the safer choice.

Your vet will start with a full history, because eye problems in leopard geckos are often tied to husbandry and nutrition. Expect questions about enclosure temperatures, humid hide access, substrate, supplements, feeder insects, UVB setup if used, recent sheds, appetite, and weight trends. A careful physical exam helps your vet look for dehydration, retained shed on toes or tail, mouth changes, and other clues that this is part of a larger problem.

For the eye itself, your vet may gently flush the eye, examine the eyelids and conjunctiva, and use fluorescein stain to look for a corneal ulcer or scratch. If there is debris or retained shed, removal may require magnification and sometimes light sedation so the eye can be handled safely. If swelling is severe or an abscess is suspected, your vet may recommend cytology, culture, or imaging to see whether tissue behind the eye is involved.

Treatment depends on the cause. Options may include lubricating eye medication, topical antibiotic drops or ointment, pain control, assisted hydration, husbandry correction, and nutrition changes including a review of vitamin supplementation. If your vet suspects hypovitaminosis A, they will guide supplementation carefully, because too much vitamin A can also be harmful.

More advanced cases may need debridement of retained material, abscess treatment, injectable medications, assisted feeding, or hospitalization for fluids and supportive care. The goal is not only to calm the eye down, but also to fix the underlying reason it happened so it does not keep returning.

Home care should support your vet's plan, not replace it. Keep the enclosure clean, review temperatures carefully, and provide an appropriate humid hide so your gecko can shed normally. Offer fresh water at all times. If your vet recommends it, gentle hydration support and prescribed eye medication can make a big difference. PetMD care guidance for arid geckos notes that retained shed around the eyes can interfere with vision and feeding, and warm-water soaking is often used to support hydration and shedding.

Do not pull at skin stuck to the eyelids, scrape debris from the eye, or use cotton swabs aggressively. Do not use human redness-relief drops, leftover antibiotics, or ointments unless your vet specifically prescribed them for this gecko. The wrong product can irritate the eye or delay healing.

If your gecko is struggling to hunt because one eye is painful, ask your vet whether temporary feeding adjustments are appropriate. Some geckos do better with closer supervision during feeding, tong-offered insects, or short-term supportive nutrition while the eye heals. Also remove loose feeder insects after meals so they do not bite or stress your gecko.

Monitor daily for swelling, discharge, cloudiness, rubbing, worsening shed problems, reduced stool output, or appetite decline. If the eye is not clearly improving within the timeline your vet gave you, or if your gecko starts keeping both eyes closed, see your vet again promptly.
