Why cant your eyelid muscles be classified as voluntary or involuntary muscles?
Eyelid muscles are in the same category as the muscles that expand your ribcage to breathe, they are only half-automatic. You can choose to blink whenever you want, and you can stop for awhile, but your body will eventually force a blink to happen. This is because for the human eye to function, it has to be wet. If blinking weren't forced, there would be a possibility of going blind

It can affect one eye or both eyes and is more common in the elderly, as muscles in the eyelids may begin to deteriorate. One can, however, be born with ptosis. Congenital ptosis is hereditary in three main forms. Causes of congenital ptosis remain unknown. Ptosis may be caused by damage/trauma to the muscle which raises the eyelid, or damage to the (3rd cranial nerve (oculomotor nerve)) which controls this muscle. Such damage could be a sign or symptom of an underlying disease such as diabetes, a brain tumor, and diseases which may cause weakness in muscles or nerve damage, such as myasthenia gravis. Exposure to the toxins in some snake and insect venoms, such as that of the black mamba may also cause ptosis.
