Myopia is also known as short or near sightedness. In this the person has difficulty in viewing the far objects but can see the near objects clearly. In this the light entering the eye is not focused on the retina but in front of it so the image is also formed in front of the retina.
The signs and symptoms of the myopia include eye strain, squinting and headache. The person may feel fatigued while driving or playing sports. Myopia can be low as well as high. If the myopia is mild it is called low myopia but if it is severe it is called high myopia. In high myopia, the eyeball stretches too long which can cause holes or tears in the retina and can also cause retinal detachment. There may be the growth of abnormal blood vessels under the retina that can cause changes in vision. It can be corrected by eye lens, eyeglasses or refractive surgery. Myopia may occur either due to heredity or due to visual stress.
