Abstract

The invention discloses a composition for relieving asthenopia, as well as a preparation method and application thereof. The composition is prepared from the following raw materials by weight percent:7-15 percent of lutein, 1-4 percent of usnic acid, 8-17 percent of saccharomyces cerevisiae extract, 10-18 percent of crithmum maritimum extract, 5-11 percent of bamboo vinegar and the balance of auxiliaries. The composition can be used for effectively relieving asthenopia, is prepared from easily available raw materials, basically does not have toxic or side effect, has an effective rate for treating asthenopia being 96 percent, can be used for improving the visual level of patients with cataract and age-related macular degeneration and improving the visual acuity and central visual field ofpatients with retinal pigment degeneration, and has a high popularization value.

Description

technical field [0001] The invention relates to the technical field of alleviating visual fatigue, in particular to a composition capable of alleviating visual fatigue, a preparation method and application thereof. Background technique [0002] Asthenopia is a common disease in ophthalmology at present. The symptoms of patients are various. The common ones are inability to use the eyes at close range for a long time, pain around the eyes and orbits, blurred vision, dry eyes, tears, etc., and severe cases have headaches and dizziness. With the increase of people's life pressure and study pressure, the crowd suffering from visual fatigue is getting wider and wider. There are many medicines and health care products for treating visual fatigue on the market, with uneven effects, and mainly chemical medicines that stimulate lacrimal gland secretion, which have certain toxic and side effects. Contents of the invention [0003] The object of the present invention is to provide a...
