This is the eye-watering moment a very brave pet pooch trustingly stayed perfectly still as a contact lens was placed onto its eye.

The video footage was shot at a veterinary clinic in Shanghai, one of the four direct-administered municipalities of China. The population of the city proper is the third largest in the world.

In the video footage, a woman explained that the dog was having trouble seeing, and the vets had advised that the contact lens was the only way to alleviate the problem.

She said that although she was apprehensive, it ended up being even easier because the dog was so well-behaved and was less problematic in the end than when doing her own contact lenses.

Although unusual it is becoming increasingly common for dogs to be given contact lenses for a number of reasons, including correcting a refractive error. Treating an eye condition such as keratitis, or protecting the eye after physical damage.

However, it always needs to be carried out with the supervision of a trained vet who is aware of the risks of infection, discomfort. And allergic reaction, and also the lenses do occasionally need to be changed to mitigate the risk of the above.

Online commentators like ‘The Sky Is Filled With Rays Of Light’ said: “Do dogs wear animal-specific contact lenses?”

And user ‘Boom Dong Tractor’ said: “He was so well behaved. Is it possible he was under anesthesia?”

While the user ‘Alia Acridine’ said: “It’s bad enough finding money to buy my own contact lenses. Never mind for the dog.”
