“My eyes! MY EYES!”

You call upon the powers of unlife to render one of the subject’s primary senses useless. The subject becomes blind or deaf, or loses one special sense it may have (such as scent, blindsight, blindsense, or tremorsense).

The name of the spell stems from its most common usage, as most humanoids rely on their sight more than any other sense.
