A quirky collection of glass eyes and vintage ophthalmology equipment, including a refraction unit and large eye chart, will go under the hammer.
Auction house owner Bridgette More said the equipment was from the personal collections of two retired University of Otago Medical School ophthalmologists.
Many people had their eyes on the unusual items, she said.
``One of our regulars said his dog hurt his eye recently; he needs one of these.''
Auction house regular Stewart Neill said he had a vision for collecting uranium glass and smoking memorabilia, but he still had a spare eye at home.
``It's just one of those things.
``When we cleared out my grandmother's estate she had a glass eye and I thought `I'll keep that','' he said, laughing.
He did not know what his grandmother, who lost her eye after getting a piece of hawthorn in it, would have thought about her eye sitting in a box.
Mrs More said taxidermy and old medical equipment were popular auction novelty items, but the ophthalmology equipment, some of which was about 90 years old, was not often seen.
