"The Blue Lenses" is another story from DON'T LOOK NOW. a collection by Daphne Du Maurier. This story so much resembled a TWILIGHT ZONE episode I was convinced I could find it online. But the somewhat similar TZ episode was THE EYE OF THE BEHOLDER and not this story.
Marda West is in the hospital following surgery on her eyes. At first her eyes are completely bandaged and she lies in bed with nothing to occupy her days. The doctor and hospital staff care for her, feed and bathe her. Her husband visits when he can get away.
When the bandages are removed, her temporary lenses, make the staff and doctor looks like various animals from the head up. Her surgeon has a dog’s head. Her day nurse has the head of a cow. Nurse Ansel has the head of a snake and her husband Jim, that of a vulture with a “blood-soaked beak.” At first she thinks the nurses are playing a cruel trick on her, but eventually she comes to realize she has been granted the ability to see those around her as they really are. The lenses have removed blindness both literal and metaphorical.
She is frightened, of course, especially when she sees that people on the street resemble animals too. Marda manages to insult everyone with her terror of their looks and eventually attempts to run away. She is captured and endures another surgery to correct the problem. This time she awakes to normal faces on everyone around her. There is one final scene you can read for yourself. You might guess what it is.
