16 Ιουλ 2020 · It takes many cells — and finally the brain — to make sense of it all. As light enters our eyes, it first heads through a tough outer tissue called the cornea. This protects the delicate inner eye from everything the world might throw at it. Light passes right through the cornea and into a transparent, flexible tissue called the lens.

The eye contains structures that allow it to perceive light, movement and differences in colour. Eyes are like cameras – they take a picture and then our brains interpret what we see. Sight is one of our senses – it helps us to be aware of our surroundings.
1 Απρ 2012 · To be able to see anything, eyes first need to process light. Vision begins with light passing through the cornea, which does about three-quarters of the focusing, and then the lens, which adjusts the focus.
15 Νοε 2023 · Light entering them activates light-sensing cells in the back of the eye. There are two types of these photoreceptors: rods and cones. Cones help us perceive color. Rods help with low-light (night) vision. Both types of receptors send electrical signals to the brain through the optic nerve. The brain transforms those signals into visual images.
30 Οκτ 2023 · How do our senses and brain work together to make us understand the world? Our senses collect information, and the brain processes this data, helping us make sense of the world around us.
It can stimulate the human eye because certain cells in the retina of the eye (photo-receptors) are sensitive to specific wavelengths of light. Very short waves of electromagnetic radiation, such as cosmic or ultra-violet rays do not stimulate vision either and remain unseen.
