Myopia or Nearsightedness

Myopia, or nearsightedness, is an error of refraction in the eye that causes objects more than a short distance away to appear blurred. It usually result from the cornea of the eye being too far from the retina, so that images are focused in front of the retina.

The error can be corrected for by concave Eye Diseases or by contact lenses, severe cases of myopia are sometimes treated by a controversial surgical distortion of the cornea known as radial keratotomy.

Many thousand people are suffer of this eye error, nearsightedness make people difficult to see something in distance such as highway sign, or object in a distance, but can see for close object and can work easily for close object like sewing.

To correct this error people can use a eye glasses or contact lens, but currently the technology have improved using eye laser surgery. The kind of this surgery as follows:
PRK is laser eye surgery that removes a layer of corneal tissue, which flattens the cornea and allows light rays to focus closer to or even on the retina.

LASIK is the most common refractive procedure a flap is cut through the top of the cornea, a laser removes some corneal tissue, and then the flap is dropped back into place.

People who are nearsighted do have higher tension on their retinas due to the shape of the eye being more oval than round. The greater the myopia, the higher the risk. As we age, the vitreous gel also weakens adding more strain.

There are specific nutrients one can take that can strengthen the retina and related connective tissue such as lutein, zeaxanthin, omega-3 fatty acids, bilberry, gingko biloba, vitamin C and glucosamine sulfate for example.

Also a diet high in vegetables (particularly the green, leafy type), low in refined carbohydrates, and void in unhealthy oils such as vegetable oils and food fried in oils helps maintain healthy vision as well.

Doing daily eye exercises can also help maintain and even improve vision. Dr. Grossman is one of the leading vision therapists in the Country. He is the author of 6 books on natural eye care.

Daily eye exercises also help maintain healthy vision. For a demo of 3 great eye exercises by Dr. Grossman, one of the Country's leading behavioral optometrists, go to http://www.youtube.com/watch?v=W10j2fL0hy0
