Myopia

Myopia also called near- or short-sightedness, is a refractive defect of the eye in which collimated light produces image focus in front of the retina when accommodation is relaxed.

Those with myopia typically can see nearby objects clearly but distant objects appear blurred. With myopia, the eyeball is too long, or the cornea is too steep, so images are focused in the vitreous inside the eye rather than on the retina at the back of the eye. The opposite defect of myopia is hyperopia or "farsightedness" or "long-sightedness" — this is where the cornea is too flat or the eye is too short.

Notes:

Over one third of our children,

although born with normal vision, become nearsighted during their school years. Many have vision that has deteriorated to the point where they would be declared legally blind if they did not have the crutch of glasses to turn to. In some highly literate Asian countries, the incidence of acquired myopia has been increasing in recent years to the point where over 90% of college students are nearsighted! The eye doctors claim this is hereditary, even when there is no history of the problem in the family. But, of all our senses, why is it just our vision that so rapidly deteriorates at such an early age? What if one third of our children walked around with hearing aids or crutches? Would that be considered just "inherited"? The excessive amount of reading and other close work that we do in our modern society is the REAL cause of acquired myopia. And the glasses with minus power lenses that are normally prescribed by uncaring doctors make the vision get worse FAST!
HOW they are viewing it. If they are wearing the glasses normally prescribed for myopia, their vision will deteriorate. you are a partner with your eye doctor in creating a visually handicapped child. The expense and nuisance of
