Introduction
For years, scientists have been studying the eyes and how they work. Fascinating things about them have been discovered about them since then, one of the subjects being vision, and how it works. The eye is built in such a way that when light reflects off of something, it enters the eyes and then from there it hits the back of the eyes (or the retina) and the focused image is sent to the brain by a nerve ending called the optical nerve, enabling the viewer to get a good visual of what they are trying to perceive. After obtaining this information about the eyes, and how vision works, an observation was made between males and females between ages 10 through 30. Do females have better visual perception using nearsightedness than males, and do males have better visual perception than females using farsightedness? What led to this question was that while observing, the females seemed to be doing a lot more activities using their vision from a closer distance such as sewing, applying makeup, cooking, etc. and the males doing activities using their vision from a further distance such as playing football, baseball, etc. so from there, the hypothesis was made that females have better vision close up, and males have better vision from far away.
Methods and Materials
In these experiments, for females and males the ages between 30 and 10 years old were used because it was questioned whether or not age would play a role in their accuracy in doing the activities. The number of males used was six, and the number of females was also six. The methods used to test this hypothesis were those seen in the observations (sewing, and catching a baseball). Both of these methods were tested on both females and males as a form of a control.
The materials used were sewing needles, string, a white cloth, a baseball, and baseball mitt. The subjects doing the experiments using their nearsighted abilities would sew a line (about 5 inches long) onto the cloth as straight as...
