Floaters are caused by the projection of opaque objects within the vitreous on the retina. Vitreous liquefaction and posterior dislocation are the main causes of floaters. Floaters often occur in middle-aged and elderly people over 40 years old, patients with high myopia, cataract surgeons, and other patients with intraocular inflammation or retinal vascular disease.
Floaters are further divided into "physiological" floaters and "pathological" floaters, and physiological floaters can be self-healing.
The vitreous humor is a special mucous colloidal tissue composed of a type II collagen fiber mesh scaffold and hyaluronic acid molecules intertwined in it. The normal vitreous humor is a colorless transparent colloid, which fills the cavity behind the lens and has the function of refractive and retinal fixation.
Vitreous liquefaction is due to the oxidation reaction of free radicals generated by light through the vitreous body with iron ions and collagen fibers in the vitreous, which degrades hyaluronic acid macromolecules, denatures and collapses the collagen fiber scaffold, and is analyzed in water, and the gel is denatured and becomes a liquid.
When the eye is myopia, especially high myopia (above 500 degrees), the eyeball will undergo elongation and deformation of the anterior and posterior diameters, squeezing the vitreous fiber scaffold, and the vitreous fiber scaffold will accelerate its collapse after being squeezed. As we age, the cumulative effect of light will also accelerate the collapse of the glass fiber scaffold.
The relationship between the vitreous and the retina is close, the lesions of the two often affect each other, the liquefaction of the vitreous will make the vitreous form a cavity, with the expansion of the liquefied cavity, the liquefied vitreous enters the retina through the tear of the posterior vitreous membrane, so that the retina and the vitreous are separated, and the patient will have floaters, flashing sensation in front of the eyes, or vision loss. In severe cases, it can stretch the retina and cause retinal tears or macular holes, resulting in severe vision loss and even blindness.
Floaters are a suitable group for Lejing.
Floaters generally increase with age, the lack of antioxidant substances in the vitreous body, and the decrease of antioxidant capacity, causing vitreous degeneration, and then producing floaters, which affects the visual quality of patients.
Lezhu contains pure natural lutein, vitamins and trace elements, which can improve the ability of eye antioxidant and so on, protect the eyes, and the effect is good.

The causes of floaters vary, but not because of a lack of lutein. Physiological floaters do not need to **; Pathological floaters (vitreous opacity): Lutein is not absorbed.

Floaters are self-conscious symptoms caused by the degeneration of vitreous opacity, which can lead to reduced vision if the degree of opacity is severe or when the cloudiness appears on the central axis of the vitreous. As people age, especially in old age, the vitreous undergoes degenerative changes, causing the original gel state to liquefy, and the appearance of fine dots, strips, nets and other turbidities, floating and wandering with the rotation of the eyeball. When light enters the eye, these cloudy shadows are transmitted to the retina, and floaters appear in front of the eyes.
1. Pay attention to rest and do not overuse your eyes to avoid myopia. Don't"Keep your eyes peeled", pay attention to frequent and complete blinking movements, and blink frequently to reduce the time that the spring ball is exposed to the air and avoid the evaporation of tears.
2. Don't blow the air conditioner for too long, avoid the air flow blowing on the seat, and place tea near the seat to increase the humidity around the seat.
3. Eat more fruits, especially citrus fruits, and also eat more green vegetables, grains, fish and eggs. Drinking plenty of water can also help reduce dry eyes.
4. Maintain good living habits, sleep enough and do not stay up late.
5. Avoid continuous operation of the computer for a long time, pay attention to the rest in the middle, usually 1 hour of continuous operation, 5-10 minutes of rest. When resting, you can look into the distance or do eye exercises.
If you can drink 9 pupil kernel tea on the basis of daily diet, it can clear heat, eliminate eye astringency, and enhance and improve eyesight.

Condition analysis: Hello this friend, floaters are divided into physiological floaters and pathological floaters. Although it is difficult to find physiological floaters, physiological floaters do not require any drugs, and the cause of their occurrence may be due to excessive eye use and long-term psychological depression.
Therefore, patients with physiological floaters only need to pay more attention to their eye health, do more outdoor exercises, practice gymnastics, and stuffy reed stools to increase their own immunity.
Guidance: Pay attention to your diet and drink water with natural minerals. It is also necessary to eat rice as the staple food, eat more green foods, and vegetables are best served cold. Fruits should be eaten something refreshing. When you relax, your eyes will return to normal.

<>2.Vitamin C and hot covering.
In addition, it is also helpful to eat more foods containing vitamin C and iodine, such as vegetables and fruits, kelp and seaweed. In addition, a simple ** method is introduced: choose the smallest hot water bottle and pour about 60 hot water.
After lying down, close your eyes, take turns to cover your eyes with a hot water bottle, cover each round limb eye for 30 seconds, and then change to cover the other eye, twice a day, for 15 minutes each time; Open your eyes about 3 minutes after the hot cover is over. Insisting on hot cover for a period of time can better reduce the symptoms of "floaters".
It doesn't matter whether floaters are or not, depending on the actual situation. >>>More
