Anthocyanins are also an important class of vision improvement essences. Commonly found in plants such as blueberries and black goji berries. Anthocyanins can promote the regeneration of rhodopsin in retinal cells, enhance eye blood circulation, and improve visual acuity. They bring rich color and vitality to the eyes, allowing us to perceive the world more clearly. At the same time, anthocyanins also have anti-inflammatory effects, helping to relieve eye fatigue and inflammation.
DHA (docosahexaenoic acid) in fish oil is also one of the important essens to improve vision. DHA is an important part of the retina, which can improve the signal transmission of the retina and improve the speed of visual response. DHA supplements help maintain the normal function of the retina and prevent vision loss. EPA (eicosapentaenoic acid) in fish oil also has a certain eye protection effect, which works synergistically with DHA to provide comprehensive protection for eye health.
Ginkgo biloba extract is also a part of the vision improvement serum. It can improve the blood circulation in the eyes, and increase the oxygen and nutrient supply to the eyes, thereby reducing eye fatigue and blurred vision. Ginkgo biloba extract also has antioxidant and neuroprotective effects that help maintain the normal function of eye nerves.
In addition to the above major vision improvement essences, there are a number of other substances that are also emerging in the field of vision improvement. For example, tea polyphenols can remove free radicals from the eye and protect retinal cells; Zinc is essential for maintaining the normal physiological function of the eye. Vitamin A is essential for vision.
These vision improvement essences work through different mechanisms, working together to protect our vision health. However, it is important to note that vision improvement serum is not a substitute for a healthy lifestyle and good eye habits. Maintaining reasonable eye time, proper rest, a balanced diet, and adequate outdoor activities are all important factors in maintaining visual health.
Techniques for feeding rabbits with vegetables
Cabbage, lettuce and other vegetables have less dry matter and less carbohydrate content. Feeding rabbits one or more vegetables for a long period of time can cause lack of certain nutrients and affect the growth and development of young rabbits. The moisture content of vegetables is about 85%, its crude fiber content is low, palatability is good, and rabbits are greedy. Feeding young rabbits within 90 days of age with vegetable leaves will cause diarrhea in only a few days. If the rabbit suffers from diarrhea after eating vegetables, it should stop feeding vegetables, add hay, dry leaves, and add 2% charcoal powder or 2% medical carbon to the mixture or mix. When vegetables are fertile due to planting, if they are re-applied with nitrogenous fertilizers, herbicides or insect pests, drought, and when the sunshine is insufficient, the nitrate content will increase. Rabbits greedy eat vegetables leaves and ingest more nitrate, stimulate the gastric mucosa, can cause gastroenteritis. After vegetables encounter pests, trampling, frost, stacking and transportation, especially in hot and humid weather, it is easy to make the nitrate contained therein become more toxic nitrite. Fresh vegetables contain nitrite at 0.1 mg per kilogram, naturally at the fourth day, 2.4 milligrams per kilogram; when rotting occurs, the content is as high as 340 milligrams to 384 milligrams per kilogram. As long as rabbits eat 100 grams of such vegetables can cause poisoning, and even death. When the amount of vegetables leaves and radish sprouts is large, such as adding chlortetracycline (0.1 g/ton), it can inhibit the growth and reproduction of reducing bacteria and prevent nitrite poisoning. Mustard, rape, radish and other cruciferous vegetables contain mustard meal. It is a glycoside, under the action of mustard enzyme, it can produce thiocyanate, isothiocyanate, oxazolidinone, nitrile and other toxins, can inhibit the absorption of iodine in the thyroid gland, causing goitre; Nitrile also damages rabbit liver and kidneys. Therefore, cruciferous vegetables should be fed as little as possible or siled and fed (silage can be detoxified). Feeding rabbits with vegetables attacked by aphids or cabbage caterpillars can cause conjunctivitis, stomatitis, gastroenteritis, rhinitis, vaginitis, abdominal pain, and diarrhea in rabbits. When feeding rabbits properly with vegetables, feed with low moisture content (such as bran, etc.) and feed with high crude fiber content (such as dried leaves, etc.) should be fed. The rabbits should be fresh vegetables without dew. Rotten vegetables can never be used to feed rabbits.
Lutein and zeaxanthin are widely known to improve vision. They are naturally occurring carotenoids in vegetables and fruits, and have a high concentration of distribution in the macular region. Lutein and zeaxanthin can absorb harmful blue light, reduce its damage to the retina, and thus play a role in protecting vision. They are like a "protective shield" for the eyes, protecting our eyes from the outside environment. In addition, these two serums also have antioxidant functions, which can remove free radicals in the eye and delay the aging of the eye.
