Eyelid

The eyelid is a movable fold of skin that lies in front of and covers the eyeball. You have two eyelids per eye: an upper lid and a lower lid. Together, they form a protective barrier that shields your eye from dust, dirt, bright light and other external influences.

The eyelids are made up of several layers. On the outside is a thin layer of skin; beneath this are the muscles that move the eyelid; and on the inside is the conjunctiva, which extends over the surface of the eye. The eyelashes are located along the edge of the eyelid, where there are also small glands that secrete oil. This oil forms a protective film over the tear film and helps prevent your tears from evaporating too quickly.

Blinking is the main function of the eyelids. On average, you blink around 15 to 20 times a minute, often without even realising it. With every blink, tears are evenly distributed across the surface of the eye, and small particles of dirt are swept towards the inner corner of the eye. In addition, you automatically close your eyelids as a reflex when something is heading towards your eye, or when you are asleep.

The eyelid margin and the glands within it also play a role in the composition of the tear film. Blockage or inflammation of these glands can lead to symptoms such as dry or irritated eyes. The eyelids themselves can also suffer from inflammation, swelling or other conditions, which can sometimes affect the wearing of contact lenses.

Eyelids and contact lenses

If you wear contact lenses, your eyelids pass over the lens every time you blink. This helps to keep the lens in place and ensures that tears are refreshed beneath the lens. At the same time, the edges of your eyelids can also leave deposits, make-up or skin oils on the lens, which can affect comfort.

You should therefore ensure good eye hygiene: clean the edges of your eyelids regularly and make sure that make-up, cream or sun cream does not come into contact with your lenses. Wear your lenses in accordance with the instructions for use and replace them on time to prevent deposits from building up.

Eyelid complaints

Eyelids can be affected by various symptoms, such as itching, redness, swelling, flaking or a burning sensation. This may be caused by inflammation of the eyelid margin (blepharitis), a blocked gland, an allergic reaction, or dry eyes where the glands do not produce enough oil.

If you are experiencing persistent symptoms affecting your eyelids, or if you notice changes such as lumps, pain or reduced vision, please have this assessed by your optician, optometrist or ophthalmologist. They can determine the cause and provide appropriate advice.

Eye hygiene and care

Good eye hygiene helps to keep your eyelids healthy and ensures comfort, especially if you wear contact lenses. Wash your hands before touching your eyes or lenses, and clean the edges of your eyelids regularly with lukewarm water or a special eyelid cleanser if you feel the need.

Avoid rubbing your eyes, especially with unwashed hands, and take care when applying make-up or skincare products around the eyes. Products containing grease or oil can get onto your lenses and affect your vision or comfort.
