IT'S A RIDDLE!

Idk what to post about, so here's a riddle I made up:

A woman with glasses is murdered. The woman has terrible vision and always wears her glasses. She is near-sighted and uses her glasses to see far away objects, but also wears her glasses when reading.

However, when she is murdered she isn't wearing her glasses. Why is this?

See if you can get the answer! :d
