From Leopard Gecko Wiki
Snake Eyes are a variation of the Eclipse morph and can occur in both the Blizzard and Tremper Eclipse as well. Snake Eyes are essentially eyes which have some solid pigment but are not completely solid.
When sold, the amount of Snake Eye is generally described as a percentage. For example, a Leopard Gecko with a Snake Eye which covers 75% of the eye would be marketed as 75% Snake Eye.
Tremper Eclipse Snake Eyes
When dealing with Snake Eyes in the Tremper Eclipse trait, it is possible to hatch Leopard Geckos with solid Eclipse eyes from two Snake Eyed parents. It is also possible to hatch Leopard Geckos with 1 Snake Eye and 1 Eclipse eye or 2 Snake Eyes.
