Hyperopia is a common disease in children. Many people believe that patients with hyperopia simply cannot see clearly from afar and cannot see clearly from near. For adults, especially those over the age of 40, this is usually the case.

Because with age, the ability to adjust weakens. When reading closely, when the Autoregulation force cannot meet the need for adjustment, the ability to see closely becomes blurred. This phenomenon is called presbyopia, which is commonly known as presbyopia.

However, for children, this is not actually the case. After birth, the eyes have physiological hyperopia and strong regulatory ability, which can be regarded as a "starting point" for eye development. This does not mean that we all need to wear glasses when we are born, but rather that there is a physiological need for adjustment.

Under normal circumstances, the regulatory power of infants and young children can reach 10-12 diopters, indicating that infants and young children can tolerate more hyperopia than adults. The ability of humans to focus and regulate gradually weakens over time. Generally, in their 40s, when the regulatory power cannot meet the regulatory needs, they begin to need reading glasses. However, the age of wearing sunglasses varies greatly from person to person, and it also depends on the "starting point" of each person's development.

Physiological hyperopia does not need to be corrected with prescription glasses, but if hyperopia causes poor symptoms such as decreased vision, headache, Eye strain, or esotropia, it needs to be corrected in time.
