Image result for what protects our lens
The sclera (SLEER-uh) is the protective layer. This tough, fibrous tissue surrounds the eyeball and attaches to the cornea, which is the clear front surface of the eye. What we see as the white of the eye is the sclera. Over the sclera lies the conjunctiva, a clear skin layer that protects the eye from becoming dry.

Why humans can't stop blinking their eyes?
The eye is designed to be self cleaning and it protects itself with blinking. The motion lubricates the eye with moisture provided by the tear duct and keeps the lens of the eye from drying and distorting. Distortion is also known by several names, but the lens will cause us to not see clearly if it is dry, just like a contact lens. The blink reflex also protects the eye from injury caused by dust or tiny objects. When the lid closes, it sweeps across the eye, removing impurities that cause discomfort.
