A picture of "blurry ham" is sweeping the internet, making people wonder if their eyesight is failing them.

But hold off on booking that Specsavers appointment for a second! The ham is blurry only because it has been sliced very thinly, giving it a semi-translucent appearance.

This 'optical illusion' of sorts has done the rounds online this week, with many wondering how the meat could be out of focus, and yet its packaging and the table under it remain in perfect focus.

Reddit user Melvin said: "Proof for all those who doubted the realness of the ham.

"And no, it's not prosciutto, it's Coburger ham. Dutch, you know.

"And therefore wafer thin."
