This is what it looks like to have Marfan’s syndrome—a condition that causes your eye lenses to dislocate, making you look like a cartoon character with “googly eyes.”

People with the disease are not in control of their eye movements, explains zyloman, the Reddit user who first shared the gif in Reddit’s WTF community.

Marfan’s syndrome is a genetic disorder that’s usually inherited, but it can also be caused by a random gene mutation if you have no prior family history of the disorder.

Though zyloman says he doesn’t suffer from any vision problems, the condition usually causes cataracts and other eye disorders, according to the US National Library of Medicine.

The user says he is still able to see fine—even if he had one of his lenses removed after it dislocated completely and “fell into the bottom of his eye.”

“It was scary but not painful,” he adds.

And it also had an unusual side effect:

But it doesn’t only affect your eyes. The disorder will make you grow unusually tall. Other symptoms include: heart problems, crowded teeth, an abnormally long arm span, narrow face, thin body, and sunken chest.

Zyloman’s height:

Incredibly, his arm span exceeds his height—measuring seven feet long.

After zyloman’s post, other Redditors with Marfan’s syndrome were also inspired to share pictures of themselves with the WTF community. Reddit user HugeJassJae shared this photo of his hands, which are larger than his face:

And Reddit user giraffesaretallsoami is double-jointed thanks to the disorder:

Meanwhile, Reddit user Bunearyy (Taryn Eason) shared this video of her hand dislocating. Amazingly, Eason says it doesn’t hurt to dislocate her own hand.
