Sight

The vision is amazing for me, because it allows us to appreciate beautiful things, for example, showing the wonders of the world, such as landscapes, seasons or a beautiful sunset.

When we want to pause, or just rest, we just have to close our eyes ... and that's it. That is one of the impressive things of this sense; having control over this allows us to do many things. 

According to many researchers in the area of health and science, the role of vision is fundamental for our lives, in fact, a deficiency of this sense when we are children, represents a difficulty in the ability to learn, both when we are children and when we are adults.

As we know, the eyes are located on the superior part of the face, between the nose and the eyebrows and the size of a human adult eye is approximately 24.2 mm.
Some diseases of the eye are for example glaucoma, dry eye, cataract and diabetic eye disease and to help keep healthy, we must take care of the sun exposure, regulate the amount of time we are on the computer, telephone or television and even not smoke too much.
