Creativity is the essence of technology we have today, without technology we would be without the most basic of equipment in our modern day lives. Could you imagine a life without cars, computers, and even houses? What would the world be like if it were deprived of these necessities? We have progressed to such a degree, that it seems almost unlikely that the human race will produce one more extraordinaire. However, without the thoughtful minds of thousands of inventors, our world would rapidly turn

We see the world around us because of the way our eyes bend (refract) light. Refractive errors are optical imperfections causing blurred vision that occur when the shape of the eye prevents light from focusing directly on the retina. The length of the eyeball (longer or shorter), changes in the shape of the cornea, or aging of the lens can cause refractive errors. Causes of Refractive Errors: The eye's ability to refract or focus light sharply on the retina primarily is based on three eye anatomy

Physics of the human eye. The human eye, what a complex but fascinating organ. It has the ability to see past the horizon and observe the different colors of a rainbow.

The eye can capture objects at various different angles, such as birds flying overhead or a person walking right beside you. Yes indeed, the eye is probably the greatest sense a person can have. The eye is so vast and complex. To
