DuoLife Clinical Formula ProOptical® is presented as a two-phase extended-release capsule.

The innovative, two-phase form combines two capsules – a liquid exterior surrounding a solid interior. The absorption process of the active ingredients contained in the liquid phase begins in the stomach, while the solid components are only released in the small intestine, from where they directly enter the circulatory system and are transported to the eyeball tissue. The biphasic absorption process of the active ingredients is characterised by the highest degree of assimilability.

ProOptical® dietary supplemnt contains lutein and zeaxanthin in their natural crystalline form, obtained via patented technology. This has an enormous impact on the speed and, therefore, the effectiveness of assimilation. The superior bioavailability of the ingredients is confirmed by over 70 clinical trials (involving more than 4,200 patients). The trials took into account the quantitative ratio of lutein and zeaxanthin (5:1), which ensures that the eye uses the maximum quantity of the most important active ingredients.

The formula of DuoLife Clinical Formula ProOptical® z has been enriched with a number of substances that support proper eye function and protect them against detrimental UV radiation and free radicals:

lutein - by absorbing blue light, it reduces photochemical damage caused by visible light with shorter wavelengths. In addition, it works with zeaxanthin to form a filter on the area of the retina responsible for detailed vision, blocking blue light and preventing blurring caused by bright light, thereby increasing the eye’s tolerance to bright light. This is particularly important when our eyes are exposed to intense light, such as sunlight, flashing lights or dazzling headlights at night. Tests have confirmed that lutein also has a positive impact on human skin.
astaxanthin - belongs to the same group of xanthophyll carotenoids as lutein or zeaxanthin and improves the accommodation of the eyes. In addition, it is important for the reconstruction of the ciliary body, thus reducing the feeling of eye fatigue, which is strongly felt every day due to working with monitors, insufficient lighting, environmental pollution, UV radiation, as well as eye defects. The raw material used has clinical tests confirming the positive effect in reducing the symptoms of asthenopia.
crocin and safranal – antioxidant substances that protect the eyes against the harmful effects of ultraviolet radiation (UV).
vitamin C derived from acerola - boosts the synthesis of collagen, a building block of the vitreous body.
zinc - a mineral component supporting optical processes; mainly found in the retina. Deficiency may cause myopia.
microencapsulated lycopene - protects the eye against the harmful effects of free radicals, it also plays an active role in the prevention of macular degeneration, as confirmed by clinical studies.
schisandrin contained in the extract of Chinese magnolia-vine -improves visual acuity in the dark.
anthocyanins - stimulate microcirculation in the eye, and enhance visual acuity after dark.

Supplements for eyes

Eye fatigue, microcirculation disorders of the retina, deterioration of vision acuity at dusk, are among others the effects of many hours of work at a computer or watching a TV screen or a mobile phone screen. With age, the eye’s defence mechanisms and its ability to cope with adverse factors gradually deteriorate, leading to more and more severe visual ailments. Deteriorating eye condition may also result from nutrient deficiency.

The correct vision processes are supported by rational supplementation.
