Women often face more challenging odds in the publishing industry than their male counterparts, and, historically, female authors confronted even more daunting obstacles in their efforts to build careers as writers.
The nerve layer lining the back of the eye. The retina senses light and creates electrical impulses that are sent through the optic nerve to the brain. The white outer coat of the eye, surrounding the iris. The, clear, gelatinous substance filling the central cavity of the eye. How the Eye Works. The five senses include sight, sound, taste, hearing and touch. Sight, like the other senses is closely related to other parts of our anatomy. The eye is connected to the brain and dependent upon the brain to interpret what we see. How we see depends upon the transfer of light. Light passes through the front of the eye (cornea) to the lens.
In broad daylight, humans can visualize objects in the glaring light from the sun, while at night large objects can be detected by starlight when the moon is dark. At threshold sensitivity, the human eye can detect the presence of about 100-150 photons of blue-green light (500 nanometers) entering the pupil. For the upper seven decades of brightness, photopic vision predominates, and it is the retinal cones that are primarily responsible for photoreception.
