*'''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 shed during normal ecdysis but may be pathologically retained (for example if mites are present, with low humidity or if the eye is diseased). | *'''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).
