The human eye is an amazing component of the body. With it, we can see! Imagine what life would be like if you couldn't see? I wear glasses, and my prescription is rather strong, but I would prefer to retain some vision than none at all!Our eyes do a lot for us, and we sometimes don't take that into consideration. You can see a loved one's smile...You can enjoy a beautiful summer's sunset...You can drive! Many of the wonderful things we enjoy and need in our lives today can be attributed to our helpful set of eyes.
Being extremely complex in design and function, the human eye is difficult to describe in detail. In essence, our eyes recognize light. Light streams through the pupil and then the lens of the eye. The lens focuses what we see (hopefully) onto the retina, where an inverted image is turned so what we see isn't upside down. The retina is also what gives us the ability to see in colour. Packed with rods and cones, which interpret light and colour respectively, the retina is a vital part of the eye. Problems occurring in the lens cause our vision to be unfocused (myopia and hyperopia).
Imagine performing a nursing procedure without the use of your eyes. Could you take vital signs blindfolded? Change a bandage? Assist in childbirth? Life would be a lot more complicated without our vision! So, it's important that we take care of our eyes so that we can work effectively and enjoy life in a full range of colour and light.
