What purpose does an eye cap serve in the embalming process?

An eye cap is utilized in the embalming process primarily to maintain the curvature of the eyelids, ensuring that the eyes appear naturally closed and correctly positioned for the viewing of the deceased. When a body is prepared for burial, it's important that the appearance is as lifelike and respectful as possible. The eye cap helps achieve this by providing a form that supports the eyelids and prevents them from sinking or becoming deformed after death, which often happens due to the loss of muscle tone.

The other options do not align with the intended purpose of an eye cap. While securing the mouth in a natural position may involve other techniques or devices, the eye cap is not used for that function. It also does not provide a cooling effect for the eyes, nor does it assist in the removal of the eyeball, which are processes handled differently in embalming procedures.
