The retina consists of many different cells, the most important of which are retinal cells. Retinal cells have a lot of mitochondria. The mitochondria in retinal cells provide the energy of retinal cell activity, including the energy required to convert light into nerve signals. However, when the sun enters the eye and is irradiated on the retina, the high-energy ultraviolet light in the solar energy causes the mitochondria in the retinal cells and retinal cells to produce free radicals. These free radicals are detrimental to retinal cells and mitochondrial intima. Long-term accumulation, in addition to free radicals directly to the damage caused by retinal cells, the serious damage to the mitochondrial intima can also cause mitochondrial decomposition, and then lead to retinal cell apoptosis. This study discloses an eye care method comprising the provision of Phyllanthus emblica extract for the use of retinal cells in the late stage of ultraviolet or ultraviolet irradiation to obtain mitochondria in retinal cells of chlorophyll extract for oxidative phosphoric acid (ATP) synthesis Higher than the mitochondria, without Phyllanthus emblica extract of retinal cells, and with triphosphate (ATP) for phosphorylation. According to the above method, the supply of Phyllanthus emblica extract retinal cells protects the inner membrane of mitochondria in retinal cells, thereby delaying the decomposition time of mitochondria, adding Phyllanthus emblica extract can also reduce the free radical content of retinal cells such as bamboo leaf extract can slow Mitotic decomposition caused by the rate of apoptosis and can reduce the effectiveness of retinal cells due to excessive free radical content and damage to protect retinal cells to achieve eye care.
