What is nearsightedness?

ANSWER

Nearsightedness, or myopia, affects nearly half of the population and the problem is growing. It is the result of images being focused in front of the retina rather than on it, so distant objects appear blurred. A nearsighted person whose eyesight has not been corrected holds a book closer to the eyes when reading and has to sit in the front of the classroom or movie theater to see clearly. The condition runs in families and affects men and women equally, usually appearing in childhood. The prevalence of myopia is on the rise and researchers attribute much of it to increased use of handheld devices and computers.
