There are "little black shadows" flying around in your eyes? We have the answer!!!

"I feel like there are always small insects flying around in front of my eyes" and "I always feel like there are dark shadows in front of me when I look at things, it's so scary" are the manifestations of floaters!

01

What are floaters?

The scientific name for floaters is "vitreous opacities". The vitreous is composed of 99% water and 1% collagen fiber scaffolds, hyaluronic acid and other substances. Under normal circumstances, the vitreous is elastic and transparent.

Once the vitreous body becomes cloudy, the light entering the eyeball projects the image of the opacity onto the retina, and small black shadows like floating, mosquitoes appear to "fly around" in front of the eyes.

As floaters get worse, the dots become more numerous and more frequent, more noticeable against a bright white background, and may be accompanied by flashes of light.

02

What causes floaters?

Floaters are divided into physiological floaters and pathological floaters .

Physiological floaters

When people are tired, "floaters" are most obvious. Older people feel floaters more strongly and obviously than younger people. This will not cause damage to the eyes and body, and no special treatment is required. Get enough rest and avoid fatigue, and it will gradually get better.

Pathological floaters

It is mostly caused by retinal tears, detachment, internal eye bleeding, inflammation, etc., and requires symptomatic treatment!

Pathological symptoms ** (need to go to hospital for treatment)**

① There is a flash in the eyes, as if the camera flash is turned on;

②In a short period of time, the number of floaters continues to increase;

③The vision is severely blocked.

How to prevent and control floaters?

If you want to prevent and control floaters, it is not as simple as repelling mosquitoes. Take an electric mosquito coil, floral water...

Most of the flying shadows that often flicker in your eyes are actually physiological floaters. There is no need to feel anxious. You can try the following methods:

1. Avoid prolonged eye fatigue

Avoid overusing your eyes, move your eyeballs frequently, keep your eyes moist, and give your eyes a rest to relieve eye fatigue.

2. Reduce strong confrontational sports

Avoid trauma and reduce strong confrontational sports, such as bungee jumping, diving, skydiving, etc.

3. Control sugar intake

Control blood sugar and blood pressure to avoid bleeding of small blood vessels in the retina. You can eat more iodine-containing seafood and foods and fruits with high vitamin C content.

4. Keep a happy mood

Relax and don't try to look at floaters.

5. If the discomfort worsens, seek medical attention immediately

If the number of floaters increases sharply in a short period of time, there are abnormal flashes in front of the eyes, and vision is blocked, you need to seek medical attention immediately. Check whether it is physiological or pathological floaters, and rule out diseases such as fundus hemorrhage and retinal tears. If the vision is seriously affected, symptomatic treatment should be given through laser or drugs.
