Outdoor activities generally do not increase the farsightedness reserve. However, outdoor activities are effective in slowing down the reduction of the hyperopia reserve, thus preventing and controlling the onset and progression of myopia.
Hyperopia reserve refers to the physiologic amount of hyperopia that occurs when a person is born. With the growth of age and the development of the eyeball, the hyperopia will gradually decrease, and accordingly, the myopic reserve value will gradually decrease.
Currently, there is no effective way to increase the reserve value of hyperopia, including outdoor activities.
However, outdoor activities can expose the human body to more sunlight, thus secreting more dopamine, which can inhibit the growth of the eyeball’s axis, and accordingly can slow down the decrease of the reserve value of hyperopia.
