If a normally-sighted child has two or more moderate risk factors for nearsightedness, then he/she should be evaluated every six months. If two or more risk factors are high, then active treatment to slow down the progression of myopia is recommended. If a child is already myopic, active treatment is recommended and he/she should be monitored every six months. Increasing nearsightedness not only requires thicker and thicker glasses, but it increases the risks of other eye diseases such as cataracts, glaucoma and retinal holes and tears.
Another risk factor for developing nearsightedness is the amount of time spent doing near vision tasks such as reading, writing, drawing, computer work and handheld games. Depending on the amount of time spent, your child may be subjecting himself to low, moderate or high risk of myopia.
Here’s another risk factor for developing nearsightedness – focusing inaccuracy. If a child displays inadequate focusing levels, then he or she will be either at moderate or high risk for developing, and worsening, myopia.
Another risk factor for developing nearsightedness is a young child’s refractive status. If a child’s visual status is less than age normal, then he/she is at medium risk for developing myopia in the future. If a child is already myopic at a young age, then he/she is at high risk for increasing nearsightedness. Prescriptions can continue to change until the age of 22 years old for most people.
Yet another reason to try to slow down how quickly nearsightedness increases is the risk of retinal detachments. Myopia, or nearsightedness, increases the risk of a retinal detachment by 4X-16X’s; the higher the prescription, the higher the risk. The retina is the tissue in the back of the eye that contains all of the nerves, cells and blood vessels that help you see. Surgery can be performed for retinal detachments. However, clinical studies show that patients who have had retinal detachment surgery complain about lower quality of life afterwards. In other words, the surgery was physically successful. However, the patients still suffered decreased quality of life due to visual difficulties afterwards.
