With the continuous popularization of modern communication tools, tools such as computers and mobile phones have become indispensable tools in people's life and office. Visual fatigue occurs more frequently due to prolonged exposure to such tools. In order to deal with visual fatigue well, it is very important to supplement eye nutrition with foods that relieve visual fatigue and restore vision to a normal state.

Visual fatigue is a common problem encountered in people's production and life. There are two main reasons for this problem. One is the visual fatigue caused by using the eyes for a long time and there is no corresponding protective measures. Visual fatigue caused by lack of external nutrition.

No matter what the cause of eye fatigue is, it should be treated correctly, because long-term eye fatigue will cause the decline of vision, so it needs to be effectively relieved when fatigued, and taking functional eye care that is helpful to the eyes Food is an effective way to relieve eye fatigue. The reason why functional foods can relieve eye fatigue is mainly because their ingredients are closely related to the nutrients needed by the eyes.

01Visual fatigue overview

Visual fatigue is a common problem that occurs in people's eyes, and with visual fatigue, it is vision loss. This phenomenon has a very obvious negative effect on people's normal eye use, and the reasons for vision loss are also various. , here we focus on three points.

The primary reason is various types of refractive errors. Hyperopia, myopia and astigmatism are all closely related to refractive errors. In daily life, people's unscientific eye posture, including poor grasp of eye rays and inadequate or untimely eye protection measures, will cause refractive errors.

The second is the clouding of the lens. The lens is a key component of the eye's structure, and cloudiness of the lens often causes cataracts, a disease that has a dramatic impact on vision.

The last one is corneal disease. The cornea is also a key building block of the eye structure, and corneal opacity can also cause very serious vision loss.

02Types of functional foods and analysis of functional components

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. Eat foods rich in vitamin A, It can effectively avoid the occurrence of the above-mentioned eye diseases.

The main effect of vitamin C can effectively reduce the damage of light and oxygen to the ocular lens, which is of great significance for protecting 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.
