Eclipse & Solid-Eye Leopard Gecko Morphs Explained
What Eclipse eyes look like
Instead of the typical pupil-and-iris eye structure, an Eclipse eye appears as one solid colour (commonly a dark 'snake eye' or solid black appearance) with no visible pupil differentiation.
Vision and light sensitivity
Geckos with fully solid eyes are commonly reported by keepers and breeders to be more light-sensitive or to have somewhat reduced vision compared to normally-eyed geckos, which can affect how confidently they navigate a brightly lit enclosure.
Husbandry adjustments
Keepers of solid-eyed geckos often use dimmer lighting, extra hides, and more caution around handling in bright conditions, since a startled reaction from reduced vision is easy to mistake for temperament rather than a sensory difference.
What to know before buying
This isn't a reason to avoid these morphs outright, but it is a genuine care consideration worth understanding and planning for, rather than discovering after the fact.

A single adult leopard gecko needs a 20-gallon long tank as an absolute minimum, with a 36x18 in (40-gallon breeder) footprint now considered the recommended standard — plus a secure lid, an under-tank heater on a thermostat, a thermal gradient, at least three hides, and a shallow water dish.
Set up in this order: substrate, then heat source wired through a thermostat, then hides and water dish, then decor — and run the whole enclosure for at least 24–48 hours to confirm stable temperatures before your gecko moves in.
Hatchlings can start in a 10-gallon tank or tub, juveniles do well in 20 gallons, and adults need a 20-gallon long as an absolute minimum — with 36x18 in (40-gallon breeder) now the widely recommended standard, not just an upgrade.
Heat a leopard gecko enclosure with an under-tank heater and/or overhead heat source (halogen or deep heat projector) wired through a thermostat — a thermostat is mandatory, not optional, and heat rocks should never be used.
Leopard geckos can survive without UVB using dietary D3 supplementation, but current husbandry guidance now recommends low-level UVB (roughly 2–6% T5) as best practice — it improves D3 synthesis, bone density, and natural behavior, and views on it have shifted significantly from older nocturnal-species advice.
Keep ambient humidity around 30–40% across most of the enclosure, with a dedicated humid hide raised to roughly 70–80% to support smooth, complete sheds.
