Your eyes give you away when you’re making a mistake — but only for certain kinds of mistakes

The eyes never lie.

Extinct monitor lizard used to have four eyes — and this is a pretty big deal

The extra eyes are called the pineal and parapineal organs.

Insects see in much better resolution than we thought

I spy, with my little thousand eyes…

Scientists find a woman that can see 99 million more colors than you or me

Just one extra cell type can make a huge difference.

Researchers coax neurons into regenerating and restore vision in mice

This could allow us to restore vision, mobility or fight diseases like Alzheimer’s.

Why we get dark circles around the eyes

Fatigue is often what causes dark circles around the eyes, but there’s more to it.

Half the world will need glasses by 2050

Nearly half the world’s population, close to some 5 billion people, will develop myopia by 2050 according to a study recently published in the journal Ophthalmology. The paper also estimates that one-fifth of these people will have a significantly increased risk of becoming permanently blind from the condition if recent trends continue.

How the eye works: what you can’t see

How eyesight works and other functions.

Looking into someone’s eyes for 10 minutes alters your state of mind and can cause hallucinations

Staring straight into someone’s eyes can be pretty intense, and is usually avoided by most people. But a team of researchers has shown that it’s even weirder than you’d think: it actually alters your consciousness, and often causes hallucinations.

Seeing the world through the eyes of a cat

As a cat owner myself, I’ve often wondered how feline vision differs from that of humans. Clearly, with their huge pupils and crocodile-like eyes, their view of the world must be truly different from ours. Artist Nickolay Lamm recently showcased a project that features various photos from two points of view: the human and the cat. While not the most

Delusional people actually see the world differently

There’s an extremely fine line between delusion and grand vision – it’s enough just to take a look back in history and you’ll find a myriad of examples where great minds who justly challenged the status quo were labeled insane, and in some even more unfortunate times, heretics. That’s not to say that behind every conspiracy theorist or person who

New theory claims Neanderthals went extinct due to larger eyes

Apparently, every month brings forth a new theory on the demise of the Neanderthals – the cookies one being that bunnies were the main culprit. This month’s theory claims that the Neanderthal skull has larger eye sockets than the human one, therefore it had bigger eyes, therefore the brain spent more of its processing power to process visual images. So

Tadpoles can see through eyes implanted in their tails

Most animals have eyes in the vicinity of their brains, typically inside the head, since these are very sensible organs that require a very sophisticated neural link. Recently, biologists at Tufts University have shown that they could implant working eyes in other locations as well, after they granted blind tadpoles vision after they implanted eyes in their tails. The findings might

Vision first evolved 700 million years ago

The origins of vision is a widely debated subject, since genetic relationships between early animals capable of sight are inconsistent. A team of researchers has conducted an extensive computer analysis that tests every proposed hypothesis on the origin of vision to date, and found a common ancestor dating from 700 million years ago. Their findings suggest vision evolved much earlier

Astronauts’ vision severely affected during long space missions

Following the advent of the space station, it’s been observed and demonstrated that exposure to weightlessness may have some deleterious effects on human health. The human body is too adjusted to the gravitational conditions on Earth, and as such extended periods of weightlessness cause various physiological systems to change and atrophy. Astronauts on-board the International Space Station battle nausea, and
