If you have difficulty seeing visions with clarity you may suffer from a number of common eye problems. But if your difficulty is with focusing on distant objects, you may suffer from a condition called nearsightedness, otherwise clinically known as myopia.
Definition of Nearsightedness
Myopia is a common vision problem which makes your eyes able to focus on near objects with greater clarity than far objects. For many individuals, this means they can focus on objects anywhere from the tip of their nose up to only a few inches or several feet.
Often the contrast between objects in focus and objects too far to focus on is a fairly sharp one. You may be able to see objects within 12 inches of your face with perfect clarity, but at 18 inches the object becomes very blurry. In contrast, some individuals find that the object becomes gradually blurry as it is moved further away.
Causes of Nearsightedness
The most common cause of nearsightedness seems to be genetic, and is the product of an eye which is elongated, instead of spherical. This means that the cornea of the eye is steeper than is ideal, creating a change in the refraction of light through the eye’s lens and making focusing on distant objects difficult or impossible without vision correction.
Nearsightedness may also be caused by certain types of drug exposure, and in theory it may be caused by viewing objects at close distance too frequently, causing the focusing mechanisms of the eye to seize in one spot or become inflexible and unable to change focus.
Treatment for Nearsightedness
You may begin to experience the effects of nearsightedness at any age, and treatment for nearsightedness can be undertaken at any time after symptoms appear. Common treatments for nearsightedness include:
- Contact lenses
- Laser vision surgery
One of the most common types of laser vision surgery for treating nearsightedness is LASIK, which reshapes the lens using a special type of “cool” lasers. These allow eye surgeons to treat vision problems without the danger of injury to the eye by the laser. While laser vision surgery will permanently correct nearsightedness, you may experience presbyopia, a common condition which produces farsightedness as you grow older.
