What does this mean: =_=(+_+)o= ), when sent in a text?

For a long time you could not include pictures in a message, so people sent simplified faces made of letters and symbols.

=_= is a face wearing funny looking glasses.
(+_+) is another face
:=) is a smiling face turned sideways
<8-D is a grinning clown face with glasses turned sideways
0=) is a smiling cyclops turned sideways
