What is peripheral vision and how does it work?
In: Biology
Peripheral vision is everything outside of the centre of your vision. When light hits your retina, the information is converted into electrical signals that are resolved by your brain to create an image. The centre of your retina, the fovea, has the greatest concentration of cones – which gives the centre of your vision great colour vision. The information from here is also less compressed, which means you have greater acuity.
Everything outside of this is mostly rods and dictates your peripheral vision, and these don’t detect colour. The information here is also compressed more, so it has less acuity. Your peripheral vision is basically everything that you’re not looking at, and because you’re not focusing on it, you’re unable to make out finer details. But your brain is able to fill in information based on context so it ‘looks’ as rich as when you’re not focusing in on it.
