Abstract

The invention discloses a composition for protecting the retina of eyes and relieving asthenopia and antioxidation, which is mainly composed of the following raw materials in parts by weight: 420 to 430 parts by weight of D-mannitol, 415 to 425 parts by weight of lactose, 90 to 110 parts of blueberry powder, 15 to 25 parts by weight of maltodextrin, 2 to 100 parts of black wolfberry powder, 0.2 to0.5 part by weight of beta-carotene, 10 to 20 parts by weight of magnesium stearate, 1 to 6 parts by weight of lutein ester and 0.5 to 2 parts by weight of (3R, 3'R)-Dihydroxy group-beta-carotene. The composition of the invention has the effects of preventing blue light damage to the retina, relieving asthenopia and resisting oxidation, beta-carotene has the function of tonifying liver and improving eyesight, lutein and (3R, 3'R)-Dihydroxy group-beta-carotene concentrates in macular area of retina through synergistic effect. Macular pigment has the function of preventing blue light damage toretina and relieving asthenopia.

Description

technical field [0001] The invention relates to an ophthalmic composition, in particular to a composition for protecting eye retina, relieving visual fatigue and anti-oxidation. Background technique [0002] With the popularization of electronic products such as smart phones and tablet computers, the blue light emitted by electronic products is more and more harmful to the eyes. Blue light can cause visual fatigue, dry eye syndrome, damage the retina and lens, seriously threaten the health of the fundus, and even induce blindness. [0003] Most of the eye protection products currently on the market are a single combination of blueberry and lutein, which is not effective in preventing blue light from damaging the retina and relieving visual fatigue. Contents of the invention [0004] In view of the above shortcomings, the object of the present invention is to provide a composition that can prevent blue light from damaging the retina, protect the retina of the eye, relieve ...
