It's difficult to overestimate importance of your eyes. These two organs help you communicate with world and give you different impressions and emotions.
Do you know, what your eyes consist of? Each of them has outer layer, called cornea, which focuses light.
Iris is a colored area that keeps the pupil (dark opening in the eye center) under the control.
After light moves through the pupil, it reaches lens and then is focused onto the sensitive cells of retina.
Retina, in turn, converts all the images into nerve impulses and send them to the brain through the optic nerve.
Special lacrimal glands, located in the corner of the eyes, secrete tears to remove debris from your eyes and to keep them well-lubricated.
Some of us got used to proper working of your eyes, while others suffer from weak sight during the whole life.
Specialists warn you that sometimes eyes can send you signals that something goes wrong in your body.
Check up these warning signs, your eyes can give you:
#1. Redness – your eyes may become reddish, when blood vessels expands. It may occur as a result of infection, high blood pressure, sun damage or allergy.
#2. Bulging – you may notice that both of your eyes become bulging, if your thyroid gland produces too much of thyroid hormones. Other symptoms of hyperthyroidism include unintentional weight loss, sleeplessness, tremor, irritability, hair loss and poor concentration.
#3. Dryness – lack of moistening may cause discomfort after several hours of looking at computer or TV. However it was found that dry eyes may be also a symptom of rheumatoid arthritis and hormonal imbalance.
#4. Floaters – dark rings, spots and lines, which appear in the vision and vanish, when you look directly at them, may make you really nervous. Floaters usually become apparent due to age-related changes, when the vitreous becomes shrinked. Be aware that any alterations in the size and/or shape of the floaters, as well as appearing of the new ones, seeing flashes and losing side vision may indicate serious health conditions like retina detachment, vitreous bleeding and tumor.
#5. Hazy vision – it's nothing to worry about, if you have poor eyesight for a long time. The problem is, when your vision becomes blurred abruptly, as it may be a sign of glaucoma, diabetes, stroke and cataracts.
#6. Night blindness – cataracts, keratoconus and lack of vitamin A can significantly impair your night vision, making it difficult to be oriented in dark places.
#7. Nystagmus – uncontrollable rapid movements, which appear suddenly in one or both of your eyes, may develop as a result of head injury, stroke, inner ear disorders or overdose of certain medications (anticonvulsants, lithium).
#8. Pain – any painful sensations and discomfort in your eyes require medical consultation, because they may be caused by wide variety of health issues, including blepharitis, corneal infection, glaucoma, conjunctivitis and stye.
#9. Different pupils – unequal pupils (medically called anisocoria) may be a congenital feature. If your pupils have become different in size suddenly, you should seek for medical help immediately, as it may be a sign of brain tumor, aneurysm, stroke and meningitidis.
#10. Ptosis – abnormal droop of the eyelid is a common symptom of serious health problems, such as stroke, muscular dystrophy, brain aneurysm and tumor.
