Myopia (Nearsightedness)

       

 

      In Emmetropia or normal vision the image is focused on the retina upside down and reversed.

 

 

 

 

      In Myopia or nearsightedness the image is focused in front of the retina.

 

 

The cornea and lens of the eye work together to properly focus visual images on the retina. When the eye is too big or the cornea is too steep, visual images are focused in front of the retina. This condition is called nearsightedness, or myopia.

Myopia normally starts to appear between the ages of eight and twelve years old, and almost always before the age of twenty. Once myopia starts, as the body grows, it often increases. It typically stabilizes in adulthood. Changes in glasses or contact lens prescriptions are necessary during growth periods.

Someone with myopia has an inability to see objects at the distance, such as street signs, chalk boards or the television. Many times, myopia is diagnosed during school screenings.

The treatment for nearsightedness includes lenses which allow visual images to be focused on the retina. These lenses can be in the form of contact lenses or glasses. Once the eye has stabilized and myopia is no longer progressing, laser vision correction is an option for many.

People who wear glasses for nearsightedness find the edge of the glass is thicker than the center.
