When should a child get his or her first pair of glasses? When he or she needs them. That may be as young as a few months of age. Healthcare providers who specialize in children's eye care say kids usually become near- or farsighted between ages 6 and 12.
Generally, there is no minimum age for children to start wearing glasses. There are some guidelines supported by the American Academy of Ophthalmology which can help decide whether to dispense glasses.
For a child between one and two years old, glasses are generally recommended if the myopia (nearsightedness) is more than -4.00, the hyperopia (farsightedness) is more than 5.00 without strabismus or 2.00 with strabismus, or the astigmatism is greater than 2.50.
