1. How does zinc affect the retina of a child?

Most of us already know that zinc is an extremely important trace element in our body. In particular, the cornea is the place with the highest concentration of zinc in the body.
Therefore, it can be said that zinc has an important role for the eyes. It helps prevent eye diseases such as retinal edema, retinal opacity, macular degeneration. In addition, zinc is also necessary for the transport of vitamin A into the retina of the eye. Zinc deficiency can affect the formation of retinal cells in the eye.
In addition, zinc also has a great effect on nerve cells in the eye. Make sure the eye cells work smoothly.
Zinc deficiency can affect the formation of retinal cells in the eye. At the same time, this is also the cause of macular degeneration, corneal edema, and corneal opacity.
Zinc deficiency for a long time, in addition to affecting all other organs of the body, can also lead to vision loss. In people with zinc deficiency, the nerve cells in the eye will be dysfunctional. Thereby making the vision lose its ability to focus, leading to hallucinations, distorted images of objects.
Experimental evidence suggests that zinc can have both positive and negative effects on cell physiology depending on the "local" concentration, locality (extracellular versus intracellular) and/or state ( association versus freedom). The retina contains particularly high amounts of zinc suggesting an important role in tissue.
There is also suggestive evidence that zinc deficiency in humans can lead to abnormal dark adaptation and/or age-related macular degeneration.
Endogenous chelatable zinc in the retina is localized mainly to photoreceptors and retinal pigment epithelial cells. Furthermore, zinc localization in photoreceptors differs in dark and light, suggesting a role for zinc in light regulation. Some zinc is also located in other areas of the retina, but the nerve cells that are high in zinc are clearly identified.
Postsynaptic neurons to zinc-rich neurons in the brain are thought to be particularly vulnerable in ischemia. The role of zinc in retinal ischemia has been investigated to determine how it is involved in this process.
It seems that when zinc is used in low concentrations, it often has a positive effect on damaged retina as in ischemia. However, higher zinc concentrations exacerbate the effects of the effects and also act as a poison. Therefore, the use of dietary zinc supplements must be exercised with caution.

2. How to supplement zinc for eyes

The best source of zinc is through food. There are many foods in nature that have high concentrations of zinc. You can supplement zinc by eating shellfish, oysters, legumes such as peas, lima beans, kidney beans, lentils... Zinc is also abundant in meats such as beef, lamb, poultry.

Or due to poor absorption of the digestive system, the supply of zinc to the eyes will be deficient. But eating foods rich in zinc does not always calculate the amount you need every day. Therefore, supplementing with zinc-containing eye supplements is also an effective measure. Zinc gluconate is present in the eye tonic, in addition to strengthening the eye's nervous system, it also has other effects such as: Improving the metabolism of vitamin A into the retina of the eye, stabilizing eye cells, reduce the risk of cell aging, prevent macular degeneration, corneal edema.
Since zinc is a trace element, not all eye tonics are available or have adequate levels of zinc. So before different eye tonics, you should consider choosing products based on the following criteria:
Zinc content: Usually, different eye tonics or eye tonics will have different functions. different amounts of zinc.

But the average zinc content in eye tonic tablets 1 day should be 1.5mg, this is a safe amount for the eyes. Prestigious eye tonic brand: Choosing a reputable brand and place of purchase is also an important thing. Most of the functional foods for health in the Vietnamese market are still imported. The use of eye tonics imported from Poland, Japan, and the US is the leading prestigious market. However, not all brands are being imported through official channels in our country. Therefore, finding and buying at reputable places is not easy. So you need to choose a place to buy with a reputable address, origin, and website.

Cost: An average course of eye tonic lasts 3 months, 2 to 3 times a year. So you need to choose good brands that are priced right for you, so that you can use each treatment session. Zinc is a trace element that is good for the body. Zinc deficiency not only affects the eyes but also other organs.
