This product uses carefully selected high-quality raw materials. Lutein and zeaxanthin are extracted from natural marigolds and encapsulated using microencapsulation technology to prevent oxidation and loss, ensuring the active ingredients precisely reach the macular region of the retina. It also contains beta-carotene, a precursor to Vitamin A, to synergistically nourish the ocular surface and mucous membranes, building a multi-layered protective system for the eyes. In protecting eye health, lutein and zeaxanthin act as a "natural filter" for the macular region of the retina, filtering harmful blue light from electronic screens and ultraviolet rays, reducing light damage to retinal cells, and lowering the risk of dry eye, retinal fatigue, and other problems. It is especially suitable for office workers and students who use computers and mobile phones for long periods, as well as those frequently exposed to strong light, relieving dry eyes, eye strain, and blurred vision caused by excessive eye strain. For eye health maintenance, the beta-carotene in the ingredients can be converted into vitamin A, which promotes the development and repair of retinal photoreceptor cells and maintains normal visual function. At the same time, the synergistic effect of multiple nutrients improves the microcirculation of the eye, delivers sufficient nutrition to the retina, delays the aging of eye tissues, and has a positive effect on preventing age-related macular degeneration, presbyopia and other degenerative eye problems in middle-aged and elderly people.
