How We See

The Normal Eye

Your eyes are an amazing and very complex system. Light from the world around you is transformed into nerve impulses. These impulses travel to our brain where we “see”.

The Visual Pathway

The Visual Pathway is the connection between our eyes and our brain. Our brain is actually where we see the world around us. First, light is focused onto the retina by the cornea and lens. Then, the retina transforms light into nerve impulses which travel via the optic nerve to the visual cortex.

Eye is Like a Camera

Light entering our eye is focused by the cornea and lens onto the retina. The retina transforms light into nerve impulses, which then travel to our brain. This is similar to the lens and photo diode of a camera system.


Your eyes are part of a very complex and beautiful visual system. Any changes to your eyes, eyelids, or vision should be brought to your eye care provider’s attention immediately.
