Give me a paragraph on outdoor activities and indoor activities which impact on myopia progression.explain these activities

Outdoor activities have been found to have a significant impact on the progression of myopia, or nearsightedness. Studies have shown that spending time outside, particularly in natural sunlight, can slow the progression of myopia in children and adolescents. This is believed to be due to the higher light levels outside compared to indoors, which can stimulate the release of dopamine in the retina. Dopamine has been found to inhibit the elongation of the eye, which is a key factor in the development of myopia.

On the other hand, indoor activities, particularly those that involve close-up work like reading or using electronic devices, can contribute to the progression of myopia. These activities require the eye to constantly focus on near objects, which can strain the eye and lead to the elongation of the eyeball, thus worsening myopia. Furthermore, indoor environments typically have lower light levels than outdoors, which means less dopamine is released in the retina. Therefore, a balance between outdoor and indoor activities is crucial in managing myopia progression.
