With the continuous development of technology, electronic products have become a must-have product in our lives. This leads to the phenomenon of eye fatigue in many people. Some natural botanical extracts can effectively relieve visual fatigue.
Wolfberry Extract Can Relieve Visual Fatigue
The chemical composition of wolfberry mainly includes sugars, amino acids, trace elements, carotene, vitamins A, B1, B2, C and other essential nutrients that are beneficial to eye health.
-Vitamin A helps relieve visual fatigue
Wolfberry is rich in vitamin A and carotene. Carotene can be converted into vitamin A in the body. Vitamin A, also known as retinol or dry eye factor, is a component of rhodopsin that senses low light in visual cells. Vitamin A plays an important role in maintaining normal visual function, can prevent night blindness and vision loss, and is helpful for the treatment of various eye diseases.
-Zeaxanthin helps relieve visual fatigue
Wolfberry is rich in zeaxanthin, an oxygenated natural carotenoid, which is an isomer of lutein. Zeaxanthin is an important component that can prevent ultraviolet rays from damaging the optic nerve of the eye. However, the human body cannot produce zeaxanthin, and it can only be extracted from food. Among them, ingesting wolfberry or wolfberry extract is an important guarantee for supplementing zeaxanthin in the human body.
-Taurine helps relieve visual fatigue
Wolfberry contains 19 amino acids, including 8 essential amino acids, with a total amount of 9.14%. At the same time, it is also found to contain aminoethanesulfonic acid or taurine, which is the only plant body reported to contain taurine, and its content reaches 0.205%- 0.0689%. Taurine is a simple sulfur-containing amino acid that exists in free form in the retina, but is not involved in protein synthesis.
In humans, decreased taurine concentration in the retina will lead to the destruction of the photoreceptor structure, accompanied by severe visual impairment and abnormal electroretinogram. Physiological levels of taurine in the retina play an important role in maintaining the structure and function of visual cells.
Ginkgo Biloba Extract Can Relieve Visual Fatigue
Ginkgo biloba is a plant with high medicinal value. Its chemical components are mainly flavonoid glycosides, terpene lactones, polyprenols, organic acids, ginkgo phenolic acids and alkylphenols, alkylphenolic acids, ginkgo acid, vitamin C, vitamin E, carotene, calcium, phosphorus, boron, selenium and other mineral elements are also very rich, more than half of the level of vegetables and edible plant materials.
According to research, ginkgo biloba has a very good effect on relieving visual fatigue. Studies have shown that ginkgo biloba has the following effects in improving vision in patients:
-Inhibits platelet aggregation
The lactones contained in Ginkgo biloba can inhibit a substance called platelet activating factor, so Ginkgo biloba can reduce blood viscosity, inhibit platelet aggregation, increase the elasticity of arterioles, increase vascular permeability, and thus increase retinal transparency. Dilate blood vessels. Ginkgo biloba can relax blood vessels by increasing the calcium ion concentration of vascular endothelial cells, increasing the activity of nitric oxide synthase, and then increasing the production of nitric oxide.
It can also dilate blood vessels by increasing PGI2 and reducing TXA2. Therefore, Ginkgo biloba can expand microvessels in the retina, reduce retinal blood vessel tension, and inhibit microthrombosis, thereby improving the visual function of patients.
-Optic nerve protection
Ginkgo biloba can increase blood supply to the choroid and retina, thereby improving visual function. It is generally believed in the medical community that during normal physiological activities, the eye needs to constantly overcome the fluctuation of intraocular pressure resistance to adjust the blood flow rate of the optic nerve. Ginkgo biloba improves central and peripheral blood flow, resets vasospasm, and reduces apoptosis. Ginkgo biloba has the effect of inhibiting glutamate toxicity, thereby slowing down the apoptosis of ganglion cells. The natural antioxidant activity of
Ginkgo biloba can effectively protect the function of mitochondria. Protects the integrity of mitochondrial structure and function by protecting against tissue and cell damage caused by different causes. Ginkgo biloba protects retinal ganglion cells by altering ocular microcirculation, protecting optic neurons, protecting mitochondria.
Conclusion
Ginkgo biloba and wolfberry are rich in a variety of nutrients that are beneficial to the eyes. In particular, it has miraculous effects in relieving visual fatigue, so it will be a very good choice to develop and apply ginkgo biloba and wolfberry to relieve visual fatigue.
