Looking from the outside in, these are the skin, the muscle layer, the connective layer (tarsus) and the joint. They also contain a large number of sebaceous and sweat glands (Meibomian, Zeiss and Moll&#8217;s), whereby the sebaceous glands play a role in &#8220;lubricating&#8221; the eye, i.e. together with the lacrimal glands that secrete tears, they enable the eyelids to slide over the eyeball more easily.   <\/p>\n<p>Blinking the eyelids is a reflex action. We normally blink about 10-20 times a minute and in this way we distribute the tears produced in the lacrimal gland throughout the eye. Frequent blinking can be caused by the sensation of a foreign body in the eye or a polluted atmosphere (eg cigarette smoke). We reflexively close our eyelids when touching the eyelashes or the eyeball itself, when illuminated by bright light or when an object suddenly approaches the eye. We can also close the eye with willpower.    <\/p>\n<p><span style=\"font-weight: bold;\">Eyelid muscles:<\/span><\/p>\n<ul>\n<li>1. <span style=\"font-style: italic;\">M.
