The pathway from eye to brain begins in the retina, where light is converted into neuronal signals.
Light arriving from the right visual field is processed in the brain's left hemisphere. So damage to the left part of the primary visual cortex will result in blindness in the right visual field.
Cataracts are one of the leading causes of visual impairment globally.

More than a million Australians have an untreated cataract and hundreds of cataract surgeries are performed daily, but what are they?
How much information is too much? And where should it go?

Augmented reality systems need to display relevant information in a useful location. That's impossible without eye tracking.
What makes your brain go all-in on what it thinks you’re seeing?

How does your brain deal with the ambiguous and variable visual information your eyes collect? Neuroscientists think it bets on what's the most likely version of reality.

The navigation tactics of certain Australian ants could point the way to helping driverless cars find their way around.
Children with albinism often have poor eyesight, so classroom seating plans are important.
In Tanzania, where albinism is common, there's plenty that ordinary teachers can do to support students with albinism – much of it quite simple.
But I asked for green highlights!

There must be some evolutionary force acting to maintain this visual 'defect'.
Pretty much all of our perception is an illusion, whether we’re walking down the street or attempting to decode the latest card trick.

Robots that can learn to 'see' the world around them -- and share their learning with other robots -- will lead the next revolution in robotics.

The pink ball introduced to this year's day night cricket test can be difficult to see for some players, especially if they are colour blind. There is a better choice of colour.
You see with your brain, not just your eyes.
Sure, your eyes are crucial for seeing the world around you. But it's your brain that does the really hard vision work.
Me, myself and eye.
The middle part of our vision sees in a much higher resolution than at the peripheries. But that's just the beginning ...
Scientists have pinned down what happens inside the brain when the scenes change in our dreams.
Your eye movements may be changing the images in your dreams when you sleep.

Study shows how eyes that work for hunters are no use for the hunted.
Bright light outdoors stimulates the release of the retinal transmitter, dopamine, which has a protective effect.
Myopia, or short-sightedness, is a condition in which distant objects appear blurred, but closer objects can usually be seen in sharp focus.
Human eyes are unique among primates for their range of iris colours and unpigmented sclera.
The science about our special senses - vision, smell, hearing and taste - offers fascinating and unique perspectives on our evolution. Yet it remains patchy; we know surprisingly little for example about…

We live in a visual world and build environments that rely heavily on visual perception. Want to find somewhere? You look on a map or read a road sign. Perhaps the GPS on your touch screen smartphone can…
The mantis shrimp has 12 types of visual cones.
As humans, we live in a colourful world, but differences in visual systems means that not all animals see the world in the same way. Unlike other aspects of an object such as size or mass, colour is not…
