9 Causes of cataract Eyes
You are at the right website if is looking for drugs, supplements or vitamins are potent pick minus eye disease, cylindrical, less obvious vision, cataracts, glaucoma, retinal and ablasio various types of other eye diseases.
Causes Eye Cataracts Cataract is a disease of the eye – where the clear lens of the eye becomes cloudy or opaque, causing a decrease in vision. Cataracts may affect different areas of the lens and can be classified according to which part of the lens they affect.
The location and extent of the cataract also determine the extent of the disruption on the vision for example: If cataracts affected the center of the lens, this can significantly interfere with vision, but if the lens edges are affected by cataracts, vision disorders may be almost invisible. Cataracts can affect one eye at a time or both eyes at the same time.
Until now, the disease is known to be a major contributor to cataract blindness around the world, we've been told even stated that the citizens of Indonesia are the country with the second largest number of cataract sufferers.
The characteristics and the main symptoms of cataracts can you recognize is the presence of fog on the eyes, the vision blurry, glare, double vision (monocular) and difficulty seeing at night. Cataract disease itself is known for its elderly disease because the disease is almost 80% suffered by those who are already advanced age (over age 40).
The aging process is the cause of most major cataracts. But in addition, there are several other causes of factors why someone experiencing eye diseases cataracts. What are some?
1. The age of
Age is the most common cause of eye diseases cataracts. This happens when the proteins in the lens decrease over time. The cause is often accelerated by some diseases such as diabetes and hypertension. Lingkunganpun factors such as toxins, radiation, and ultraviolet light, have a cumulative effect, which was compounded by the loss of the protective and restorative mechanisms due to changes in gene expression and the chemical processes in the eye.
2.Trauma/injury
Trauma or injury to the part of the eye can cause disorders such as causing swelling, thickening, and lens fiber bleaching. This trauma usually can be cured by itself although white color can persist.
But when injuries or severe trauma occurs in the eye or there are wounds that penetrate the eye, located underneath the capsule of the lens is damaged. This allows liquid damage from another part of the eyes to quickly get into the lens that leads to swelling and then bleaching the lens, causing the light from reaching the retina at the back of the eye.
3. Radiation
Ultraviolet rays, especially UVB RAYS have been shown to cause cataracts, and some evidence suggests sunglasses worn at an early age can slow the development of cataracts in later life. Microwave radiation has also been found to cause cataracts. the mechanism is unclear but may include changes to the enzyme was sensitive to heat that normally protects the protein cells in the lens. Another possible mechanism is direct damage to the lens of the pressure waves induced in the aqueous humor.
4. Genetics
A strong genetic component in the development of cataracts, most commonly through a mechanism that protects and nourishes the lens. The presence of a cataract in childhood or early life can sometimes be caused by a specific syndrome.
Some genetic disorders are derived that causes other health problems can increase the risk of cataracts. Examples of chromosome abnormalities associated with cataracts including 1q deletion syndrome, syndrome 21.1 cri-du-Chat syndrome, Down syndrome, Trisomy 18, this Por (Edward's syndrome), and Turner's syndrome, and in the case of neurofibromatosis type 2.
The skin and the lens have the same embryologic of origin and can be affected by a similar ailment. Those with atopic dermatitis and eczema occasionally develop ulcers shield cataracts. Autosomal recessive Ichthyosis is a disorder associated with cataract and nuclear sclerosis pointy.
Smoking
Smokers have significantly increased the risk of cataracts compared with non-smokers. In fact, studies show that people who smoke have double the chance of having cataracts. Doctors believe smoking contributes to cataracts by changing the lens cells through oxidation. There is also evidence that smoking causes the accumulation of heavy metals like cadmium in the lens.
Alcohol
Alcohol has been shown to interfere with calcium homeostasis in the lens, increasing process such as damage to the membrane, altering the protein-protein interactions, and produced a pro-oxidants molecule when metabolized in the liver. Some studies have stated that excessive alcohol consumption can improve the formation of cataracts. Meanwhile, recent work by the team of Boston University found that heavy consumption of alcohol (more than two drinks per day) increased the serious risk of cataracts.
Drugs
Some drugs, such as inhalation of corticosteroids may increase the risk of developing cataracts. Types of Statins – drugs also researchers from the University of Waterloo, Canada, reported in the journal Optometry and Vision Science that people who take Statins have a higher risk of age-related cataracts.

The best way to prevent cataracts is to maintain a healthy lifestyle. In fact, there are four lifestyle changes You can be made to prevent or slow the development of cataracts such as paying attention to a healthy diet, avoiding foods that are not good for eye health, conduct regular inspections to doctors and keep the weight off.
