A small, thin plastic lens that is placed directly on the cornea of the eye to correct a vision problem. It is an alternative to glasses.
example
Ich trage lieber Kontaktlinsen als eine Brille.
I prefer wearing contact lenses to glasses.
Usage tips
Compound word
The word is built very logically: it consists of 'Kontakt' (contact) and 'Linse' (lens). So it is a lens that is in direct contact with the eye.
EXAMPLE
Die ersten Kontaktlinsen waren noch aus Glas und sehr unbequem.
The first contact lenses were still made of glass and were very uncomfortable.
Typical verbs
In connection with contact lenses, there are three important verbs you should know: 'Kontaktlinsen tragen' (to wear contact lenses), 'einsetzen' (to put in, into the eye), and 'herausnehmen' (to take out, out of the eye).
EXAMPLE
Ich vergesse morgens oft, meine Kontaktlinsen einzusetzen.
In the morning, I often forget to put my contact lenses in.
Use in the plural
Although the word also exists in the singular, people usually talk about 'Kontaktlinsen' (contact lenses) in the plural, since they are normally used for both eyes.
EXAMPLE
Meine Kontaktlinsen sind mir ausgegangen, ich muss neue bestellen.
I've run out of contact lenses; I need to order new ones.

Kontaktlinse vs Brille
glasses
'die Brille' and 'die Kontaktlinse' both help with seeing when someone has a vision problem. The difference is their form and how they are worn. Glasses sit in front of the eyes in a frame. A contact lens sits directly on the eye and is barely visible from the outside. The words can be confused because both have the same purpose and are often alternatives to each other. If you wear something on your nose, you say 'Brille'. If the lens sits directly in the eye, you say 'Kontaktlinse'.
Kontaktlinse
Vor dem Schwimmen nimmt Mehmet seine Kontaktlinsen heraus.
Before swimming, Mehmet takes out his contact lenses.
Brille
In der Pause putzt sie ihre Brille, weil die Gläser schmutzig sind.
During the break, she cleans her glasses because the lenses are dirty.
