the blind spot from person to person. However, there are certain conditions that could cause damage to the retinal wall, thus causing nerve damage to he photoreceptors, thus causing a blind spot. This damage may cause an additional blind spot in the visual field; of if damage occurs to the retina surrounding the natural blind spot, the natural blind spot could essentially be enlarged. (Windsor and Windsor, 2003; Hall, 2003; and Seddon and Kuijk, 1998).

There are several factors that can effect eye health, such as nutrition and general health. It is generally assumed that athletes have an overall healthier lifestyle than the general public. They are assumed to engage in habits that promote good health such as eating more nutritiously, exercising and maintaining a generally higher level of health than the general public. It is therefore the premise of this study that athletes would be expected to have fewer eye-related health problems and that these problems would result in fewer visual blind spots or smaller naturally occurring blind spots than in non-athletes.

This study will use methods for mapping blind spots in the chiropractic field to measure the blind spots of a group of athletes and a group of non-athletes. This research will support the hypothesis that the group of non-athletes will be found to have larger blind spots due to decreased general health.

Literature Review
The existence of a blind spot in each eye is a naturally occurring anatomical trait and therefore has received very little academic attention in itself. There has been limited attention to the study of how our brain "compensates" for this phenomenon, however, once explained, it received very little attention. The blind spot can be located if a person trains their attention to it. There is a simple visual test; contained in APPENDIX I that can help a person "see" the blind spot in their right eye.
