14 things your eyes say about your health
Dark circles, styes, sparse eyebrows or eyesight at night ... By being attentive to the condition of your eyes, you can detect in advance of serious health problems, such as stroke or cancer. Here are fourteen signs that should alert you:
1. persistent red Circles
Even getting enough sleep, sometimes dark circles persist. This may be allergies that give you allergic rhinitis. Usually, you will have red eyes, itchy and even sneezing and runny nose. Allergens cause dilation of blood vessels. Is visible under eye skin which is the thinnest of the whole body . If they are red buttons shaped plates "wolf" (mask), it could be lupus erythematosus, an autoimmune disease.
2. The white of your eyes become yellow ...
It's jaundice. It is likely that your skin is also yellow. Jaundice is a symptom of liver dysfunction (viral hepatitis, hepatitis caused by drugs, autoimmune hepatitis, alcoholic hepatitis, Gilbert's syndrome, tumor) or gallbladder (gallstones, cholestasis of pregnancy, tumor) that affects the bile.
What is the relationship with the yellow?
Bile contains a toxic yellow pigment bilirubin. When producing too much bile or that your body has difficulty evacuating, this yellow pigment will come accumulate in your eyes and in your skin. We must mention the jaundice of the newborn, common in premature babies whose liver is only half. There is treatment with special lights that help degrade the yellow pigment. Jaundice is also evident when you do not have enough red blood cells (hemolysis), as in people who suffer from anemia. 
This is also the case of malaria where the liver destroys the infected red blood cells to fight the disease.
3. A persistent stye - swollen and painful eyelid
A stye is a small boursoufflure on the eyelid, along the lashes. It is not painful as such, but it itches. Styes itches like "chassie" these crusts that form around the eyes at night. If your stye does not go away by itself after three months, and he often returns to the same place, it is important to consult a specialist. This may betray a rare form of cancer: sebaceous carcinoma . The sebaceous gland is a small organ located at the base of each bristle body. It produces sebum, fat hair.
4. See blur, having dry and sore eyes at the computer
The screens that surround us often lack contrast. To read these screens, our eyes have to work hard - this is a major constraint exerted on them.
After several hours, you can:
It hurts the eyes + headaches
Have dry eye and red
have double vision
This problem has a name: the computer vision syndrome. 
5. beady eyes
Eyes that seem out of their sockets can betray a thyroid problem.  In this case, the thyroid gland is overactive. The Greek term for the bulging eyes is exophthalmos.
6. sparse eyebrows
If the outer third of your eyebrows disappear, you should check your thyroid. You may be suffering from hyperthyroidism.
7. Mal see at night
If you notice that your vision is worse at night, you should consider increasing your intake of vitamin A, particularly betacarotene. To perceive light, your eye needs a pigment called rhodopsin. This is vitamin A that you will get it.  For this, eat more vegetables (and fruit) orange and yellow, such as carrots, sweet potatoes, oranges, lemon ... but also fatty fish.
8. See the twinkling lights
The "scintillating scotoma" manifest before an ophthalmic migraine with aura. 
Attention migraine is best defined as headache: Migraine, it is severe pain, localized, arriving in the form of violent impulses and prevent continue daily activities. Physical exertion increases the pain. People with migraines do not tolerate the noise and light. They feel nauseous.
The plant that kills your migraines
The spigélie, poisonous plant, effectively treats migraines powerful following the cycle of the sun: the pain begins at the base of the neck, the left side, and spread in an arc to above the left eye.
9. lines that become curves
It is also a harbinger of migraine with aura.
10. Points black spots in the visual field
Another sign that announces migraine with aura. 
If the stain is fixed in the visual field, this can be the macular degeneration (AMD) or a disease of the retina. It is therefore important to consult a doctor.
If after 50 years you have stains that move when your eyes move, it is "flies", that is to say, a vitreous detachment.  This problem is less urgent.
11. Red Spot in the eye
If one morning you wake up with the eye while red is a small blood vessel exploded. If this happens often, it's probably that you have high blood pressure . In observation, your eye doctor will see a narrowing of the blood vessels in your retina.
12. Suddenly seeing double, or even see dark blindness stroke =
Without pain, you can suddenly see dark, double vision or even blindness. These are the signs of a Stroke (stroke). It is important to remember these warning signs.
There are other signs of stroke that appear suddenly:
Difficulty communicating. It becomes difficult to speak and understand.
The paralysis of a limb
Loss of balance 
13. Symptoms of Stroke + PAIN
If you have these symptoms of stroke (see dark or double blindness suddenly) and you also hurt the eyes ... it is perhaps of optic neuritis, an inflammation of the optic nerve. Often, optic neuritis precedes by a few years multiple sclerosis, an autoimmune disease of the central nervous system. Multiple sclerosis is terrible. It paralyzes the body. It robs you of your sensory perceptions. It also destroys your memory. Many patients even stop talking.
14. A diabetic who sees trouble
Type 2 diabetes (diabetes mellitus) often have eye problems. The most common is the retinopathy because circulation problems diabetes also affect their eyes. Patients' eyes are damaged because they are not properly oxygenated. We observed many cases where patients with diabetes become partially blind. In Canada, most people who lose their sight before age 65 have type 2 diabetes.
