Nearsightedness, known as myopia, makes it difficult to see objects far away and is caused when images are focused in front of the retina. This typically occurs when the eyeball becomes longer, which is common in children who are growing quickly. The changes may be frequent, and glasses or contact lenses may need to be updated often.
Farsightedness, known as hyperopia, makes it difficult to see objects that are close and is caused when images are focused behind the retina. This can be a result of the eye being too small. Many times, farsightedness occurs at birth. Some children outgrow the condition without experiencing many symptoms.
