Sehen vs. ansehen vs. schauen
The German verbs sehen, ansehen, and schauen all relate to the act of seeing, but they are not interchangeable. The main differences lie in the level of intent and focus, with sehen being the most general and passive, while ansehen and schauen describe a more active and intentional act of looking.
Sehen
A1Sehen is the most general term, meaning to see. It describes the physical ability to perceive with your eyes. It is often a passive act; something simply enters your field of vision. It can also be used for watching movies or shows, and figuratively for understanding something.
Ohne meine Brille kann ich fast nichts sehen.
(Without my glasses, I can see almost nothing.)
Hast du den Regenbogen gesehen?
(Did you see the rainbow?)
Ich sehe, was du meinst.
(I see what you mean.)
Man sieht selten so viele Sterne.
(One rarely sees so many stars.)
Ansehen
A2Ansehen means to look at or to watch something intentionally and with focus. The prefix an- directs the action towards a specific object. It implies a more thorough or concentrated observation than sehen. It is a separable verb, often used reflexively (sich etwas ansehen).
Sieh mich an, wenn ich mit dir rede!
(Look at me when I am talking to you!)
Der Arzt muss sich die Wunde ansehen.
(The doctor has to look at the wound.)

(We looked at the new museum yesterday.)
Er sieht sich das Gemälde sehr genau an.
(He is looking at the painting very closely.)
Man sieht ihm an, dass er die ganze Nacht nicht geschlafen hat.
(You can tell by looking at him that he didn't sleep all night.)
Schauen
A1Schauen also means to look and implies an active, intentional gaze, similar to ansehen. However, it often feels more casual, less intense, and can describe looking in a general direction or for a longer, more relaxed period. It's often used in Southern Germany and Austria, where it can be synonymous with the Northern German gucken.
Schau mal, ein Eichhörnchen!
(Look, a squirrel!)
Er schaut gedankenverloren aus dem Fenster.
(He is looking out of the window, lost in thought.)
Ich schaue gerne den Wellen zu.
(I like to watch the waves.)

(Can you look in the fridge to see if there is any milk left?)

(In the evening, we often watch TV.)
Summary
In essence, use sehen for the general ability to see or for passively noticing something. Use ansehen for an intentional, focused look at a specific object or person, often to examine it. Use schauen for a more general or casual act of active looking, similar to to look or to gaze. While ansehen is about focusing *on* something, schauen is often about looking *in a direction* or casually watching.
