Flies, shroud before the eyes, rainbow circles and doubling

Here is a list of phenomena that can change your vision :

• Shroud before the eyes.
• Spots before the eyes.
• Iridescent circles when you look at a lighted object like a street lamp or a headlight of an approaching car.
• Loss of peripheral vision: you see, but only narrowly in front of you, not at your sides.
• Double vision.
• Flashes of light or zigzag lines.
• Blind spots.
• Intolerance to bright light.
• Bad central vision - you see better on the sides.

The causes of these symptoms - and many others - usually fall into one of the following categories:

• Local disturbances in one eye or both.
• Weakness of the muscles that control the movement of the eyes.
• Neurological problem inside the brain.
• Disease not associated with the eyes or brain.
• Reaction to medicines.
• Injury.

To "fetch" the exact cause, first glance at your home medicine chest.

The shroud before the eyes, specks and iridescent circles can be caused by medications . Some drugs, including antidepressants, cortisone, calming, contraceptive pills, heart and drugs used in Parkinson's disease, impair vision, increasing pressure in the eye. This can worsen the already weakly expressed glaucoma and will give blurred vision, loss of peripheral vision, iridescent circles when you look at the lights, and overall reduction in visual acuity.

If you have a double vision (doctors call it diplopia), it is important to know whether this occurs in one eye or both. (It's possible to see everything double with only one eye.) To determine this, cover one eye for a while. If you still double, the problem is local in this eye. However, if double vision is observed only when both eyes are open, then something affects the ocular muscles, the most common causes are vascular disorders of the brain: usually stroke, myasthenia gravis, increased thyroid function, diabetes or brain tumor .

If you are 40 years old or more and you started seeing spots or floating objects before your eyes, do not worry. This is a very common phenomenon in completely healthy elderly people, it indicates the presence of intermediate products of metabolism. You are more likely to see these spots if you are short-sighted. Over time, they will less bother you. If , however, the spots are so much or they are so large that they interfere with the vision, visit the eye doctor.

If suddenly you see as if a shower, a shower of sparks through a veil before the eye - you may have had a retinal detachment. This often happens in the elderly with myopia. As the lens of the eye bent, the reticular membrane behind it was wrapped and separated. Consult a doctor immediately. Laser treatment at the earliest stage can work wonders while in the past an incurable disease.

Did the bright light suddenly annoy you? Many people with thin skin can not tolerate bright light. However, if this symptom is new to you, it may indicate infection, inflammation, or eye trauma . It also occurs in glaucoma and some types of cataracts. Find out.

If you suddenly notice a blind spot, when you look directly in front of you, and it lasts for several days, visit a doctor. You could have a hemorrhage inside the eye.

If you see bright spots, iridescent circles, zigzag lines or lost peripheral vision followed by a severe headache, you have a migraine attack . These vision disorders will soon pass.

If you are a diabetic and suddenly notice a periodic or constant twitching, your eye muscles become weakened by the disease. This symptom is usually temporary.

If you are 60 or 70 years old and you double in the eyes for several minutes or hours, this is probably the result of a spasm (a transient ischemia attack ) or a blockage in one of the brain arteries ( stroke ), especially if you have high blood pressure. Consult a doctor immediately.

If you are less than 40 years old and suddenly you start to double in your eyes or your eyesight is smeared and besides you noticed an unstable gait, the most likely cause, at least according to statistics, is early multiple sclerosis . Although the victims of this disease for a long time may feel good, multiple sclerosis usually progresses over the years.

If you are a woman between 30 and 40 years old and take birth control pills, smoke and you have foggy or double vision, the cause is a vascular disorder in the brain . Although this is partly the effect of hormones, the main fault lies with cigarettes.

If you have diabetes , you may find that on some days your glasses are good, and in others you see through them blurry. These changes are associated with fluctuations in the sugar content of the blood. Do not waste money on new glasses, because nothing will change until you stabilize the blood sugar content.

If you suddenly blinded to one eye and vision did not recover quickly, it is possible that the central artery of the retina behind the eye is clogged up with either a blood clot or arteriosclerosis (arterial densification). This is an emergency case . Immediately contact your eye doctor. It can save your eyesight if you get to it quickly enough.

Here are a few other options to keep in mind.

You are over 50, every muscle in your body hurts and tenses for several days, you have a small temperature, lost your appetite, and you feel weak. Suddenly, as if all this is not enough, you will blind in one eye. You almost certainly have temporal arteritis, inflammation of certain arteries of the head. The diagnosis requires a biopsy and when it is confirmed by immediate cortisone treatment. The alternative is blindness!

If you are 60 years or more, you have glaucoma, diabetes or high blood pressure and you begin to notice a gradual weakening of vision in one eye, probably the central vein of the retina (not the artery) is clogged. Again, this is a case that requires immediate help, and you must contact the doctor as soon as possible.

If you are a woman before menopause , take birth control pills and you have flashes of sparkling lights in your eyes followed by periods of temporary blindness - it's a migraine .

If you are over 60, you lose central vision and you see better on one side, you have age- related macular degeneration . This is part of the aging process, and in our time it can neither be prevented nor cured.

Vision is an invaluable gift, the loss of which is a tragedy. For any of the symptoms described above, consult a doctor immediately.
