Snakes are often presented to the veterinarian for eye problems so knowledge of the normal anatomy of the ophidian eye is essential.  Learn more about examining snake eyes in [[Snake Physical Examination|this section]]  The eyesight of snakes is relatively inefficient and the eye is reduced or absent in some fossorial snakes.  They rely heavily on [[Snake Special Senses|special senses]].

*'''Spectacle''' - The embryologically-fused eyelids (hence no palpebral fissure) form a transparent covering of the eye called the spectacle (also known as the brille or eyecap).  Between the spectacle and the cornea are tear-like secretions.  The spectacle is [[Snake Shedding|shed]] during normal [[Ecdysis|ecdysis]] but may be pathologically retained (for example if [[Snake Mites|mites]] are present, with low humidity or if the eye is [[:Category:Snake Diseases|diseased]]).  [[Snake Retained Spectacles|Retention of the spectacles]] has been associated with the development of corneal disease and panophthalmitis.
