The iris changes the size of the pupil, depending on how bright the light is. The lens focuses the light onto the back of the eye: the retina. The retina is a mass of light-sensitive neurons, called photoreceptors, which change light signals into electrical ones. 15jonesg https://padlet.com/15pricea4/eyeeyecaptain/wish/129078380 2016-10-07 11:47:15 UTC https://padlet.com/15pricea4/eyeeyecaptain/wish/129078380 here is some facts about  colour blindness 15pricea4 https://padlet.com/15pricea4/eyeeyecaptain/wish/129079477 2016-10-07 11:51:57 UTC https://padlet.com/15pricea4/eyeeyecaptain/wish/129079477 The most common form of 'colour blindness' is red-green colour deficiency, which affects 7-10% of people. This is not actually blindness, but a difficulty in distinguishing shades between red and green. It is caused by a change to or loss of the light responsive chemical in certain photoreceptors. Total absence of colour vision, where everything is seen in shades of black and grey, is very rare, and is usually caused by brain damage. 15jonesg https://padlet.com/15pricea4/eyeeyecaptain/wish/129079485 2016-10-07 11:52:00 UTC https://padlet.com/15pricea4/eyeeyecaptain/wish/129079485 Photoreceptors contain chemicals that change when they are hit by light. This causes an electrical signal, which is then sent to the brain along the optic nerve. Different types of photoreceptor allow us to see an enormous range of light: from starlight to full sunshine, and all the colours of the rainbow. https://padlet.com/15pricea4/eyeeyecaptain/wish/129079856 2016-10-07 11:53:43 UTC https://padlet.com/15pricea4/eyeeyecaptain/wish/129079856 15pricea4 https://padlet.com/15pricea4/eyeeyecaptain/wish/129080868 2016-10-07 11:58:06 UTC https://padlet.com/15pricea4/eyeeyecaptain/wish/129080868 https://padlet.com/15pricea4/eyeeyecaptain/wish/129082097 2016-10-07 12:03:58 UTC https://padlet.com/15pricea4/eyeeyecaptain/wish/129082097 Diagram of the inside of your eye https://padlet.com/15pricea4/eyeeyecaptain/wish/129082206 2016-10-07 12:04:32 UTC https://padlet.com/15pricea4/eyeeyecaptain/wish/129082206 The average blink lasts for about 1/10th of a second.While it takes some time for most parts of your body to warm up to their full potential, your eyes are on their “A game” 24/7.Eyes heal quickly.
