Clark Ashton Smith's "A Star-Change" aka "The Visitors from Mlok" (short story, free): Being appropriately human considered better than being more than human

Lemuel Sarkis, unhappy with life, is taken by two aliens to their world, Mlok. A world in a galaxy so distant its light is yet to reach earth!

Only problem is: local lights & sounds are hard on humans senses, & make Sarkis sick. So aliens treat his senses so he'll be comfortable.

Later, Sarkis needs to be returned to earth in a hurry because of a local emergency. And he discovers his altered senses now find earth's normal sensations unbearable...
