Causes
The eyeball is longer than normal or too large, which affects the cornea and lens having too short focusing power, so light rays will be focussed at a point in front of the retina, rather than directly on its surface. Myopia often progresses throughout the teenage years, when the body is growing rapidly.

Symptoms
Nearsighted people usually see well up close without corrective lenses. Myopia people often have headaches, blurred vision or feel fatigued when driving or playing sports. If you experience these symptoms while wearing glasses or contact lens, you may need a comprehensive eye examination.

Treatment
Myopia occurs when the eye cannot focus the light properly. Glasses and contact lenses are the ways to correct it. Today, several surgical treatment options are available such as PRK, LASIK, LASEK, or EIPILASIK
