Commonly known as nearsightedness, myopia (the opposite of hyperopia) is a condition in which an image of a distant object becomes focused in front of the retina, either because the eyeball axis is too long, or because the refractive power of the eye is too strong.
Myopia is the most common refractive error requiring correction seen in children. This condition makes distant objects appear out of focus and may cause headaches and/or eye strain. You may notice that your child is holding books too close to his/her face and writing with his/her head very close to the table.
Eyeglasses or contact lenses may help to correct or improve myopia by adjusting the focusing power to the retina.
