The retina is a thin layer of tissue that lines the back of the inside of the eye, located near the optic nerve.
The role of the retina is to change the light focused on to it by the eye’s lens into a signal that the brain can then ‘see’ as a visual image.
Thanks to the retina, we can recognise colours and we can see different intensity of light – light and shade. This means we can carry out all out our basic daily tasks such as reading and driving.
The mechanism by which we see involves the teamwork of the retina capturing the light through its photoreceptor cells, together with the optic nerve which conveys the information through the optic nerve at the back of the eye to the brain. We then rely on the brain to tell us what the image really is, so we can understand it.
If something interrupts this visual process, such as damage to the retina, it may lead to vision loss and even blindness.
Because of the retina’s vital role in vision, any damage to it can cause permanent blindness.
