Does it always feel blurred vision when it's cold? Beware of all kinds of eye diseases caused by vasoconstriction of eyes.

Uncle Lin has been feeling blurred vision recently. He thought that presbyopia might have been more serious, so he tried on presbyopia glasses in an optical shop, but it was still blurred. At the suggestion of his boss, he went to see a doctor and found that the blood vessels around his eyes were blocked, and the wind almost went in his eyes!

My vision is blurred when the weather is cold. When the weather is cold, everyone knows that blood vessels contract, so I try to keep my shoulders, knees and other joints warm. Of course, my neck and head are also essential to avoid the stroke crisis caused by vasoconstriction. But for eyes, although they spend the longest time every day and are prone to fatigue, few people will notice that they also need to keep warm until their vision becomes blurred.

In order to keep clear and bright like a lens, the eyeball itself has no blood vessels, but there are many microvessels around it, which are responsible for transporting oxygen and nutrients to the eyeball and sending away the metabolic waste of the eyeball. If the peripheral blood vessels contract, harden or are blocked for other reasons, the retina will not be able to metabolize normally due to aqueous humor, resulting in edema and blurred vision. In severe cases, eye wind may occur, leading to blindness.

When the weather is cold, the eyes are easy to dry. In addition, modern people use too many eyes, the mobile phone slides in the quilt, and the light is insufficient. It may cause the ciliary muscles to be too tight to adjust the eyes to relax. If you still have photophobia and sore eyes, it means that the degree of myopia is beginning to rise, so you should pay attention to the problem of using your eyes.

Cold weather may cause temporary dark vision problems.

Before falling down, some stroke patients had a bad headache and had a good experience every few minutes. In fact, the blood vessels were blocked at that time, but at first the body still had a certain self-healing ability to temporarily open the blood vessels, but this represented a high-risk precursor of stroke. The same is true of subretinal vascular occlusion. Temporary blurred vision may appear first, but it will recover every few minutes. At this time, don't neglect it. Go to the ophthalmology department quickly to avoid the wind in your eyes and your eyesight will not come back.

Eye strokes

The wind in the eyes is retinal vascular obstruction, which leads to temporary blindness. There are two kinds of obstruction, one is arterial obstruction and the other is venous obstruction. The vision can hardly be recovered due to arterial occlusion, while the vision due to venous occlusion may be saved, but it will definitely decrease. If the premonition of stroke is not treated, it may also cause eye bleeding and form other diseases.

Hemorrhagic macular disease

Macula is the most sensitive part of the retina, which is responsible for absorbing unnecessary light that the eyes can't accept, such as blue light, and the metabolism of the retina. If new blood vessels are formed under the retina due to dry eye, or the blood vessels under it bleed, it will lead to macular edema, so that the center of the eye can not be seen. Only by grasping the treatment within a week can we preserve our eyesight, and we can't ignore the warning because of our eyesight.

Vascular glaucoma

On that day, the air became cold and the blood vessels contracted, which could not provide enough blood for the eyeball. However, under the condition of long-term eyeball ischemia, there will be problems in eyeball metabolism, and the aqueous humor responsible for metabolism in eyeball can not obtain nutrition smoothly and can not be discharged, which leads to the increase of intraocular pressure and oppression of optic nerve. If irreversible damage is caused to the optic nerve, vision cannot be restored, and in the most serious case, it will lead to blindness.

shortsighted

This is the same as the above. When the weather is cold, the regulation of muscles and blood vessels will definitely get worse. If you don't give your eyes enough rest time, the deepening of myopia can be imagined. High myopia is also a high risk factor including cataract, macular degeneration and glaucoma. It is suggested to avoid the chance of deepening myopia.

In fact, as long as you hot compress your eyes for 65,438+00 minutes every day in winter to relax and rest your eyes, you can reduce the chances of many eye diseases. Then, do a good job in general eye care, don't slide your mobile phone lying down, don't slide your mobile phone in places with insufficient or too strong light, and rest for 65,438+00 minutes with your eyes for 50 minutes. At the same time, we should pay attention to our three highs and chronic diseases.
