Abstract

The invention relates to a composition for preventing and improving visual fatigue and a preparation method thereof. The composition comprises the following raw materials: 10-40 parts of blueberry freeze-dried powder, 5-10 parts of acerola cherry powder, 20-50 parts of xylitol, 20-60 parts of sorbitol, 2-5 parts of lutein ester, 0.5-2 parts of beta-carotene, 1.2-5 parts of citric acid and 0.2-2.4parts of magnesium stearate. According to the composition disclosed by the invention, under the synergistic effect of anthocyanin in the blueberry freeze-dried powder and vitamin C in the acerola cherry powder, the elasticity of microvessels is enhanced, microcirculation of retinal blood capillaries is enhanced, the attack of free radicals to eyes is reduced, and cells are repaired, thus achievingthe effect of relieving the visual fatigue and improving degenerative eye disease; and under the synergistic effect of the anthocyanin in the blueberry freeze-dried powder, the beta-carotene and thelutein ester, eye diseases including senile macular degeneration, cataract and the like can be effectively prevented and assisted-treated.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to a composition for preventing and improving visual fatigue and a preparation method thereof. Background technique [0002] Visual fatigue is a group of syndromes caused by various causes that make the human eye exceed the load that its visual function can bear when viewing objects, resulting in visual disturbances, eye discomfort, or systemic symptoms after using the eyes, so that it is impossible to perform normal visual work. . With the continuous increase in the demand for close-distance work such as video terminals and reading, the continuous popularization of electronic products such as mobile phones, computers, and tablet computers, and the extension of contact time, coupled with the increasingly serious environmental pollution (dust, light pollution, etc.), visual fatigue The number of patients is increasing year by year. Visual fatigue mainly includes ocular man...
