Eyes is the most vulnerable and delicate part among our senses. With technology and pollution, our eyes are constantly under strain, resulting in conditions such as cataracts, glaucoma, infections and macular disease.
COMMON EYE CONDITIONS
CATARACTS – Clouding of the lens inside the eye, resulting in blurred or dim vision. If the lens of the eye thickens and becomes clouded or opaque, it becomes unable to focus or admit light properly. Some causes of cataracts include aging, diabetes, heavy metal poisoning, exposure to radiation, injury to the eye, and the use of certain drugs, such as steroids. The main symptom of a developing cataract is a gradual, painless loss of visions. Cataracts are the number one cause of blindness in the world. Occasionally, a cataract may swell and cause secondary glaucoma. Cataract can be prevented and even be reversed through proper nutrition, supplements and lifestyle changes.
GLAUCOMA – A group of eye conditions in which the optic nerve (the nerve at the back of the eye) is damaged. Glaucoma is a serious eye disease marked by an increase in the pressure that the fluids within the eye ball exert on other parts of the eye. If this pressure is unrelieved, it may harm the retina and ultimately damage the optic nerve, resulting in vision loss, even blindness.
ITCHY OR TIRED EYES
Itchy or tired eyes can be the result of many different factors, including allergies, eye strains, fatigue, infection (conjunctivitis), and an inadequate supply of oxygen to the cornea and outer eye tissue.
AGE-RELATED MACULAR DEGENERATION (AMD)
The leading cause of vision loss, affecting mostly those over the age of 50. It is caused by damaged macula. In general, it is basically caused by hardening of the arteries that nourish the retina, depriving the tissue of oxygen and nutrients. This loss of vision may appear suddenly or it may progress slowly. Macular degeneration is probably the result of free radical damage similar to the type of damage that induces cataracts. Factors that predispose a person to developing macular degeneration include aging, atherosclerosis, hypertension, and environmental toxins.
DIABETES RETINOPATHY
Occurs when tiny blood vessels inside the retina at the back of the eye are damaged due to diabetes. The disorders in which some of the tiny capillaries that nourish the retina leak fluid or blood that can damaged the rod and cone cells. New capillaries then begin to form in the injured area, and these also interfere with visions. Problems with the blood vessels can cause retinal haemorrhage (leakage from the vessels that transmit the fluids of the eye), microaneurysms (abnormally enlarged blood vessels in the eye), retinal edema (the accumulation of fluid in the eye) and perhaps, loss of vision. Unfortunately, there are no warning signs;the condition usually causes no symptoms until it is relatively advanced.
DRY EYES
Dry eyes occur when the tear ducts do not produce enough fluid(tears) to keep the eye moist, resulting in burning and irritation. This problem is more common in women then in men, and women’s susceptibility increases after menopause. Contact lens wearers are particularly prone to developing dry eye problems. Dry eyes generally lack of Vitamin A, and are more likely to effect people over the age of sixty five.
EYESTRAIN
Eyestrain causes a dull, aching sensation around and behind the eyes that can expand into a generalized headache. It may feel painful to focus the eyes. Eyestrain is commonly a result of overuse of the eyes for activities requiring close, precise focus such as reading or computer work.
FLOATERS
Bits of cellular debris floating within the eye are commonly referred as floaters. Because these floaters cast shadows over the retina, the individual sees small specks that moves slowly before the eyes, especially in certain lights and against certain backgrounds. Most floaters eventually become less noticeable and are considered benign. Floaters that coalesce into long, stringy strands may be caused by a disorder called fibrillar degeneration of the vitreous. This condition is usually caused by excessive exposure to sunlight.
