Waking up a few hours after normal bedtime and not sleeping again, sleep deprivation causes the skin to become dull and bruised under the eyes. In such cases, the skin becomes sensitive and causes dark tissues to appear. Allergic Reactions: Allergic reactions and dry eyes also trigger dark circles under the eyes.
The most usual cause of a black eye is a forceful hit to your face. However, there are some other possible causes, such as nasal surgery and cosmetic eye surgery. Swollen eyes and eyelids can also result from a severe tooth infection, sinus infection, and some types of dental work.
Causes of a Bruise
These bruises result from microscopic tears in blood vessels under the skin. Unexplained bruises that occur easily or for no apparent reason may indicate a bleeding disorder, especially if the bruising is accompanied by frequent nosebleeds or bleeding gums.
When you're stressed, blood is provided to other parts of your body, barring the face, which makes it look very pale. This causes the blood vessels underneath your eye to be more apparent, eventually giving birth to dark circles.
The tissue around the eyes is thinner than the skin on almost anywhere else on your body, and the delicate skin has equally delicate blood vessels right underneath. When you rub your eyes, those tiny capillaries and veins break very easily, and this causes bruising that makes dark eye circles even worse.
Seek medical care right away if you have vision problems, such as double vision or blurring. Also seek care right away if you have severe pain, bruising around both eyes, or bleeding in an eye or from the nose. Apply warm or hot compresses. This may be helpful after a few days when the swelling has gone down.
See a Doctor for a Black Eye If:
There was loss of consciousness as a result of the injury. Black eyes appear affecting one or both eyes after a head injury; you should be examined by a doctor for possible skull fracture. You have blurry or double vision. You can't move your eyeball in all directions.
A bruise (contusion) happens when small blood vessels break open and leak blood into the nearby area. An eye bruise is often caused by something hitting the eye or nose. You may have pain and swelling around the eye. The skin may also change color.
Allergic shiners, also called allergic facies or periorbital venous congestion, are a symptom of allergies. They appear as dark circles under the eyes and resemble bruises or “black eyes.” Allergic shiners are caused by the pooling of blood under the eyes, due to the swelling of the tissue in the nasal cavities.
Generally, ice is considered the best treatment for black eyes. Once the swelling goes down, you can use a warm compress and gentle massage. Your black eye should heal after 2 weeks.
If you lose vision or partial vision in only one eye and you're not having pain, you may be having an eye stroke, or retinal artery occlusion. It's a medical emergency.
First, it will be red, then it will gradually change to dark blue, deep violet, and possibly black. Pain may be felt either constantly, or only if someone touches the affected area. Sometimes there is a red patch on the eye. This is a subconjunctival hemorrhage.
A black eye is bruising and swelling around your eye, usually caused by a blow to the area, such as a punch or fall. It should get better within 2 to 3 weeks.
Because the skin under your eyes is very delicate, even a minor injury can cause a lot of blood to pool underneath.
A subconjunctival hemorrhage is when a blood vessel breaks in the white of the eye. Then blood builds up below the conjunctiva. It causes a flat, bright red patch in the white of the eye. It is similar to a bruise on the skin.
The exact cause of them is unknown, but it is suspected that instances of increased blood pressure such as sneezing or coughing violently, heavy lifting or even laughing forcefully can lead to this condition. In other instances, burst blood vessels in the eye can be caused by: Rubbing the eye intensely.
It could be normal for eyes to look a little swollen when you wake up in the morning, but severe eye swelling is not. The most common causes of new eyelid swelling include allergies, pink eye, and styes, but skin infections, thyroid disease, and herpes are other possible causes.
Swelling under the eye can develop for a wide range of reasons, from mild conditions, such as allergies or blocked tear ducts, to more severe conditions, such as organ failure. If a person with swelling under the eyes also has difficulty breathing or is in severe pain, they should seek immediate medical help.
Most people with eye stroke notice a loss of vision in one eye upon waking in the morning with no pain. Some people notice a dark area or shadow in their vision that affects the upper or lower half of their visual field. Other symptoms include loss of visual contrast and light sensitivity.
Call 9-1-1 immediately if any of these signs of stroke appear: Numbness or weakness in the face, arm, or leg; Confusion or trouble speaking or understanding speech; Trouble seeing in one or both eyes; Trouble walking, dizziness, or problems with balance; severe headache with no known cause.
Some people will experience symptoms such as headache, numbness or tingling several days before they have a serious stroke. One study found that 43% of stroke patients experienced mini-stroke symptoms up to a week before they had a major stroke.
Sometimes black eyes can occur without trauma affecting the eye. If you have bad nasal allergies, you can get “allergic shiners.” These shiners may cause dark circles or the appearance of a black eye because blood flow is slightly hindered.
In people with fairer, thinner skin, blood vessels may be more visible, especially under the eye, and they can give the area a blue or purple hue.
After the blunt force injury, blood vessels burst and collect under the skin, especially in the area of the lower lid, due to the force of the blow. Since the skin around the eye is thin, it's easy to see the ruptured vessels – which produces the dark red or black color.
