Analysis of Functional Food for Relieving Visual Fatigue And Its Functional Components

Vitamin food
Vitamin foods can effectively relieve visual fatigue, and foods rich in vitamin A and vitamin C are the main ones that relieve visual fatigue.

The main effect of vitamin A is to promote the regeneration of rhodopsin. In practice, the lack of rhodopsin can lead to night blindness, dry eye, and even more serious corneal softening and corneal ulcers. Eating foods rich in vitamin A, It can effectively avoid the occurrence of the above-mentioned eye diseases.

The main function of vitamin C can effectively reduce the damage of light and oxygen to the ocular lens, which is of great significance to protect the ocular lens. Cataract disease can be well relieved due to the action of vitamin C.

Mineral food
Mineral foods also play an important role in relieving visual fatigue. Elements such as calcium, chromium and zinc play an important role in normal eye activity.

Among them, calcium is closely related to bone growth. When the eyes are developing and growing, the lack or insufficiency of calcium will cause myopia, so we must pay attention to the supplement of calcium in the process of eye use. The main effect of chromium element can activate insulin, so as to ensure the normal level of insulin supply. Lack or insufficient supply of chromium element can also induce myopia.

Lack of zinc can directly lead to visual impairment, because zinc is the main component of bone and blood structure, zinc can participate in the metabolism and transportation of vitamin A in the eyes, and maintain the medium and long operation of retinal pigment epithelium. series of eye diseases.

Lutein food
The efficacy of lutein products is mainly related to lutein. Lutein is the main component of the macula in the eye. Lutein can prevent the aging of the retinal macula and has a positive effect on retinopathy.

In clinical trials, lutein can effectively prevent blindness caused by muscle degeneration, and lutein also has a prominent role in filtering ultraviolet rays and other rays that can cause great damage to the eyes.

In the current era of popularization of computers and mobile phones, active use of lutein products can effectively reduce the damage caused by radiation factors to the eyes, thereby relieving visual fatigue.

Anthocyanin food
The main component of anthocyanin products is anthocyanins, which is a European bilberry extract, which has a significant effect on relieving eye fatigue.

The primary function of anthocyanins is to protect capillaries and promote the regeneration of red blood cells. The capillaries of the eye structure are very developed, and the damage of the capillaries will directly cause eye trauma, and the protective effect of anthocyanins on the eye capillaries is very obvious.

Another significant function of anthocyanins is to improve the eye's ability to adapt to darkness. This improvement in adaptability is also of great help in relieving visual fatigue.

Kelp
The most prominent feature of kelp is its high iodine content. In modern society, kelp is also a very effective food for relieving visual fatigue. The main reason is that kelp is rich in mannitol.

The outstanding efficacy of mannitol has a diuretic effect, which can effectively reduce the pressure on the eyes, which has a positive effect on the treatment of acute glaucoma.

In addition, wakame, which is similar to kelp, also contains mannitol, so it is generally used for the adjuvant treatment of acute glaucoma.
