Why Can't You Look at the Sun During a Solar Eclipse?
Looking at the sun during an eclipse is more dangerous than looking at full sun. The darkness that accompanies an eclipse can override the natural tendency to squint and avert the eyes, increasing the amount of ultraviolet radiation landing on the retina and making it more likely that you'll sustain eye damage. Your eyes can sustain damage even if only a small sliver of the sun is visible. The cornea focuses sunlight on the retina and scorches it, and because the retina has no pain receptors, you don't know the damage has been done until it's too late.
The psychology of Perception involves the interaction of our senses and our conscious mind. Perception is involved in every aspect of our lives as we make decisions and judgments based on what we experience. If you study diligently you will leave this course with a broad understanding of sensation and perception. From this general understanding you will be able to further investigate areas of interest by means of literature review and research on specific topics.
