Introduction

Sight is the ability of the human eye to be able to detect and focus images of visible light. This process occurs because of the light on the photoreceptors found in the retina of each eye. The sense of sight is important to all animals and human beings as it leads them by enabling them to focus on their path. Without the sense of sight, people would not be certain of their direction and others would prefer to remain stagnant. This paper explores several facts concerning the eye. In addition, the paper explicates myths refuting the eye facts

Discussion

Firstly, research establishes that on average, the eye is only 2.3 centimeter long. Despite its short width, the eye has capacity to focus on several things at the same time. Secondly, the eyes resemble brains in complexity. This fact is because the eyes contribute to visualizing images and thoughts alongside the brain. Thirdly, despite been compact in size, the eye has millions of working parts. For instance, the eye blinks close to 12 times in a minute resulting to almost 10,000 blinks in a day (Optometrists, 2011). An amazing fact about the eye is that despite the color blind people detecting color, they confuse the shade of the color. Lastly, the eye functions with a 100 percent ability during night, and daytime (Optometrists, 2011).

Despite all the facts concerning the eye, there are several myths discovered concerning it. Some myths claim that the eye cannot function well in dim light. This means a person should not read in dim light. Secondly, some people believe that the eyes should not undergo check up until a person is above forty years (Keller & Nichols, 2001). This is a myth, as we know the eyes develop infections that require medical attention. There is also a myth that claims using ones eye’s on a video display terminal is harmful. This goes against the fact that the eyes work 100 percent during the day and night (Keller & Nichols, 2001).

Conclusion

The eye is an important organ to animals and human beings. There are several facts regarding the eye such as their perfect function during day and night time, their small size, and the capability of focusing several images at once. A myth refuting the fact that the eyes work well during day and nighttime is that the eyes can be harmed if used near a video display unit.
