The woman had bought the "all-day comfort" lenses online.
"They felt uncomfortable all day. When I took them out, the left one had stuck to my eye," she told the daily.
She said her vision became blurred and she was given drops by her doctor.
"A white pocket of pus started forming over my pupil and eventually burst, splitting my eyeball," she said.
"I was screaming. I was given morphine, but it didn't touch the pain. I've given birth twice but nothing compares to that. I could feel the bug eating through my eye."
She went to a Cambridge hospital, where she was diagnosed with an infection caused by the Fusarium fungus.
It had eaten through three layers of her eye and 70 nerves.
After 22 surgeries, surgeons were forced to remove her eye.
The woman is now suing two local hospitals and the contact lens company.
The Fusarium fungus affects the cornea - the front part of the eye - and can cause blindness. Symptoms include blurred vision, discharge, swelling, tears, pain and sensitivity to light.
