This question has been the center of an ongoing debate for many years by vision scientists and eye doctors. Nearsightedness is also known by the scientific name myopia. Myopia is an optical or refractive defect of the eye that causes blur in the distance. Depending on the degree of nearsightedness, a nearsighted eye is able to see clearly at some point up close. That is why the term nearsighted is used.

Consider these facts: Science cannot fully explain how our two dimensional retinas create our three dimensional perception of space, texture, and color; over 70% of all incoming sensory fibers to the brain originate in the eyes; vision allows independent movement such as walking, driving, biking, etc.; vision is necessary for the appreciation of art and nature; and vision affects all aspects of human life. Given these facts, it isn't surprising that maintaining quality vision is a top priority as we age. Diminished sight not only leads to diminished physical function and independence, but also impacts a person's sense of joy and beauty and how they experience the world around them.
