The Human Eye

May 27, 2014

The Human Eye is the 'window to the world'; the most complex camera equipment in the world. Not surprising with terms like lens, focus, vision and axis dominating the functioning of the eye, it requires the complete functioning of a variety of parts to process images that we see and help us see them better.

The eyes are a very delicate feature and susceptible to injury and damage. As we age, the body itself starts to show signs of wear and tear, just like any piece of machinery that has been in use for a very long time. Considering the amount of activity that we carry out on an average day with our eyes, it must be quite simply the most utilized part of our body. Hence, it is absolutely necessary to protect the eyes and maintain eye health, which we sometimes take for granted.

These days, along with keeping the body in shape, people are taught eye exercises to prevent the eyes from damage due to excessive use at work, harsh lights hitting them, dust and other particles damaging the sensitive portions and from illnesses like cataract, glaucoma etc. This is more so because with technology advancements we have come to rely totally on electronics like computers, mobile phones, TV sets to gather information, to carry out our work duties and for leisure and entertainment.

The eyes also require proper nutrition and exercise to prevent degeneration of tissue and muscle that can even lead to loss of eyesight. Proper nutrition with the right kinds of foods and complete rest can ensure that the eye continues to function well and delight us with the images of life that we see all around us.
