A blue-eyed leucistic ball python looks like a snake carved from ice, but that pale gaze isn’t a trick of the light alone. It takes two copies of a rare gene pair, such as Lesser and Butter, and each egg from a het pairing carries just a 25% shot at it.
Your snake’s eyes can also turn blue for a completely different reason. Fluid builds up under the old skin, and a milky haze rolls in for days. One cause is permanent, the other is temporary, and mixing them up can cost you.
Here’s how to tell snakes with blue eyes apart, care for them, and spot trouble early.

Key Takeaways
- Blue eyes in your snake are either permanent, as in blue-eyed leucistic ball pythons that inherit two BEL complex genes like Lesser and Butter, or a temporary shedding haze, so knowing which one you’re seeing keeps you from misreading your snake’s health.
- Shedding blue usually lasts 3 to 4 days (up to 10 for some snakes) and clears 24 to 48 hours before the shed, so keep humidity at 50-70%, offer a humid hide, and skip handling while your snake can’t see well.
- You should call a vet if cloudy eyes persist after the shed, since retained eye caps look grainy and opaque, or if you notice swelling, bulging, discharge, lethargy, or weight loss.
- Blue eye color doesn’t affect your snake’s vision, so if you buy a blue-eyed leucistic ball python, choose a captive-bred one from a breeder who provides lineage records and health guarantees, and be ready for a commitment that can last 30 years.
Snakes With Blue Eyes: Pet Morphs and Wild Examples
Not every blue-eyed snake gets its color the same way. Below, you’ll meet the leucistic ball pythons bred for blue eyes, then the wild snakes that show similar shades. Use the list to tell a true blue eye from a look-alike.
If you’re weighing a purchase, this guide to ball python morphs with blue eyes shows which gene combinations produce the bluest eyes and why they cost more.
Blue-Eyed Leucistic Ball Pythons
A Blue-Eyed Leucistic Ball Python isn’t a single gene. You get one when your snake inherits two BEL complex genes, like Lesser and Butter. That’s leucism with vivid blue eyes. Each het pairing gives you 25% odds per egg.
Breeders often favor combinations such as Lesser x Mojave because they tend to produce clean, very white offspring.
Watch the shedding process closely, since bug-eyed BELs can retain eye caps. Otherwise, you’ll care for them like any ball python.
Wild Eye Colors and Look-Alikes
Wild snakes rarely match leucistic ball pythons. True blue eyes from genetic mutations are extremely rare outside captivity.
Most blue you’ll spot is a look-alike:
- Shedding process: fluid clouds the ocular scales.
- Light scattering in the iris.
- Pale eye pigmentation in albino snakes.
- Leucistic gray ratsnakes, rarely.
- Emerald tree boas from Guyana.
Check your snake’s shed cycle before you panic.
If your snake’s eyes look cloudy or old skin clings to its tail and eyes, this guide to signs of snake shedding problems can help you spot trouble early.
What Causes Blue Eyes in Snakes? Genetics, Pigment, and Light
Blue eyes in snakes don’t come from a single cause. You’ll find three main reasons below, and each one tells you something different about your snake. Start with genetics, then work through light and shedding.
Genetic Changes Affecting Pigment
Picture a leucistic ball python coiled in the light, pale as milk, with eyes the color of glacier ice. That look starts in the DNA.
Leucistic ball pythons carry genetic mutations in the EDNRB1 gene. You need two copies to get leucism, and heterozygous snakes may show striping instead. Don’t confuse this with amelanistic traits, which affect melanin alone.
Light Scattering and Color
Those glacier-ice eyes aren’t blue pigment. Leucistic ball pythons simply lack pigment, so light refraction does the work. You see:
Albino ball pythons, by contrast, have pink eyes and yellow-on-white coloring, and their albino ball python care guide explains why dimmer lighting keeps these light-sensitive snakes comfortable.
- Short wavelengths scatter most.
- Structural anomalies in iris tissue bend light.
- Sparse pigment distribution lets blue show.
- Dark pigment would absorb it.
- Angle changes the shade.
That’s why blue eyes look different from every angle. Watch the shade shift yourself.
Temporary Blue During Shedding
The milky blue haze in your snake’s eyes is a normal part of the shedding process. Fluid buildup between the old and new skin layers scatters light and clouds the spectacle. Your snake can’t see during this blue phase, so it may act defensive.
Keep humidity at 50-70% so the molting cycle finishes cleanly and retained eye caps don’t form.
Why Snake Eyes Turn Blue During Shedding
When your snake’s eyes turn blue during shedding, it’s a normal sign that a new skin is coming. Here’s what to expect, from how long the blue phase lasts to how you should care for your snake along the way. You’ll also learn when cloudy eyes mean it’s time to call a vet.
How Long Blue Eyes Last
Most blue eyes last 3 to 4 days. That’s the typical window in the shedding process, though some snakes stay cloudy for up to 10 days.
The color usually clears 24 to 48 hours before the shed. Temperature, humidity, and your snake’s age all shift the timing within the molting cycle.
Leucistic ball pythons’ genetic mutations keep blue eyes permanent.
Safe Care During The Blue Phase
Picture a snake gliding through its enclosure with milky, sky-colored eyes, half blind and on edge. That’s the blue phase. Keep humidity at 65-70% and offer a humid hide with damp sphagnum moss.
Skip handling until the shedding process finishes. Add rough branches or rocks so shedding goes smoothly. Afterward, check for retained eye caps.
When Cloudy Eyes Need Veterinary Attention
Think you can just wait it out? Usually, yes. Blue eyes during the shedding process are normal. But some signs aren’t.
Call your vet if you see:
- Cloudy eyes after the shed, since retained eye caps look grainy and opaque.
- Swelling or bulging, which suggests fluid buildup behind the transparent ocular scales.
- Discharge, lethargy, or weight loss.
Does Blue Eye Color Affect a Snake’s Vision?
Do blue eyes make a snake see worse? No, they don’t. Your snake sees just fine.
In leucistic ball pythons, the color comes from missing iris pigment scattering light, not from a blue dye. Genetic mutations change how pigment cells migrate, but the retina still works the same way. Human studies show iris color doesn’t change visual acuity, and nothing suggests snakes differ.
A leucistic ball python’s blue eyes come from light scattering off missing pigment rather than blue dye, and they don’t impair its vision
What does affect sight is the shedding process. Each eye sits under a clear spectacle, one of the ocular scales, and fluid pools beneath the old one before it sheds. That film turns your snake’s eyes milky blue and blurs its vision for several days. Expect a jumpy, defensive animal, so skip handling until the eyes clear.
Responsible Ownership and Conservation of Blue-Eyed Snakes
Would you commit to 30 years of care for a snake you’ve just met? A Blue-Eyed Leucistic Ball Python can live that long, so responsible ownership starts before you buy.
Buy only captive bred morphs from breeders who show lineage records, offer health guarantees, and answer questions after the sale. Skip lines with known problems like spider wobble or spinal kinking. These genetic morphs in snakes take generations to produce, so ask how the breeder built them. Before you bring one home, a solid ball python care book can help you judge a breeder’s answers and spot red flags early.
Your choices support conservation efforts too. Captive breeding eases pressure on wild populations, while wild-caught animals and careless releases harm ecosystems. Check your local exotic pet laws and permit rules first.
Set aside an emergency vet fund and respect your snake’s handling limits. Keep a reptile emergency first aid kit stocked with wound cleanser, gauze, and a small heat source so you can respond quickly until the vet takes over.
Frequently Asked Questions (FAQs)
What snakes have blue eyes?
You’ll spot blue eyes in the Blueeyed Leucistic Ball Python, emerald tree boas, sea kraits, and corn snake morphs like Palmetto and Ultramel Anery.
Genetic morphs in snakes and leucistic ball pythons alter ocular pigmentation.
Do blue eyed snakes have olfaction?
Wondering if blue eyes dull your snake’s nose? Not at all.
Chemosensation in squamates relies on the tongue, vomeronasal system, and olfactory epithelium. Keep scent cues steady and familiar in your enclosure and habitat setup.
What color are Snake Eyes?
Snake eyes come in every color imaginable! Snake eye pigmentation ranges from brown and gold to red, while leucistic ball pythons show blue. Albinism gives pink.
In the blue phase, cloudy ocular scales hide everything.
Do leucistic snakes have blue eyes?
Among captive-bred morphs, pair Mojave with Lesser, and roughly one in four eggs hatches a Blue-Eyed Leucistic Ball Python. Still, you’ll see gray or black eyes in other leucistic snakes, so blue eyes aren’t guaranteed.
Why do snakes have blue eyes?
Blue eyes look like a gift, but they’re usually a warning. During the blue phase, fluid fills the space under your snake’s ocular scales for several days.
Leucistic ball pythons keep theirs through genetic mutations.
Can blue-eyed snakes see in the dark?
Picture a pitch-black burrow where something warm slips past.
Its pits handle thermal gradient detection, true infrared vision, while nocturnal visual adaptation helps little. Blue ocular scales and light scattering in ocular media don’t matter.
What kind of snakes have blue eyes?
Start with the BlueEyed Leucistic Ball Python. Breeders combine genetic mutations to produce near-white leucistic ball pythons with blue eyes. Texas rat snakes come in a similar morph.
Cloudy ocular scales before shedding don’t count.
Are blue eyed snakes rare?
Yes, they are. The Blueeyed Leucistic Ball Python exists almost only as one of the captivebred morphs, because leucistic ball pythons need selective breeding to get blue eyes, and white snakes rarely survive in the wild.
Do garter snakes have blue eyes?
Picture a dark bead glazed with milky sky. That’s your garter snake mid-shed. Blue eye color variation here is temporary fluid, not pigment. Leucistic reptiles and captivebred morphs differ, so don’t trust species identification alone.
Do snakes have eyes?
Yes, they do, even if they look blank. Snakes have two eyes, each covered by a clear spectacle, not eyelids.
Leucistic ball pythons’ blue eyes involve genetic mutations and iridophores. A blue phase means shedding.
Conclusion
Picture a pale gaze drifting across a terrarium, cold as sea glass. Whether it’s a rare gene or a shedding cycle, snakes with blue eyes are telling you something. Permanent blue is a morph you chose. Temporary blue is a phase you manage.
Keep humidity steady, handle less, and call a vet if the haze lingers past the shed. Know which blue you’re looking at, and your snake gets a whole lifetime of clear sight.
