i've been having my gecko for over 3 years now and she always had her left eye like this. i thought she was blind at first but then i found out it's called "snake eye" and some geckos have that. but her eye is not like this all the time as you can see on the next photos. does anyone know what exactly it is and does anyone have a gecko with eyes like this too? is she okay?
