Understand What Nearsightedness Is And If It Is Treatable?


Nearsightedness (myopia) is one of the most common eyesight disorders. Today, it is more widespread in the USA than it was 30 years ago*.

People with poor vision due to myopia surely know what is nearsightedness, what treatment and prevention methods are available. Those who still enjoy perfect vision and specifically people involved in activities that require constant eye concentration, need to learn what is nearsightedness, what may cause it and which the best treatment options for myopia are.

Studies suggested several causes of myopia. In the past it was widely considered that the inability of a person to see distant objects is primarily hereditary. In other words, if you have a family history of myopia, you will be myopic too. However, recent studies suggest that a number of environmental and lifestyle factors also contribute to the onset and development of nearsightedness. Furthermore, the risk factors of nearsightedness affect virtually every person - even those with no family history of eye diseases or eyesight disorders.

The best way to understand what is nearsightedness and which factors may increase your risk of nearsightedness is to look at the basic cause of myopia. Nearsightedness may occur in childhood or in adulthood and it develops when the eyeball elongates (becomes egg-shaped and not round). This irregularity of the eyeball causes light to focus in front the retina instead on it. The result is blurred distant vision which becomes worse as myopia progresses.

The changes of the eye shape may be hereditary - a person may be born with longer eyeball than normal. They may also develop later in life and be triggered by frequent and prolonged close eye work, lack of eye relaxation, poor nutrition and so on.

But nearsightedness is treatable - people with nearsightedness may choose between prescription eyeglasses, contact lenses and corrective eye surgery. If eyeglasses and contacts are undesirable and eye surgery seems a risky choice, one can consider a number of effective natural vision correction methods.
