Cataract refers to the total or partial cloudiness or opacity of the lens inside the eye.
They can be small, or large, causing obvious loss of vision.
They are most common in people over 55 years of age, but sometimes occur in younger people and even babies.
Causes of Catarct
Although no direct causal link has been established, age, hereditary or damage to the eye have been suggested as the trigger for chemical change inside the eye which turns the lens cloudy, both eyes are usually affected but not at the same an identical rate.
At present, no one knows how to prevent the formation of cataract, but protecting the eyes from UV exposure is recommended ( wearing sunglasses or tinted lenses)
Since no pain or redness is experience with cataracts, symptoms to note are hazy / blurred vision or a film over the eyes, spots in front of the eyes, even growing sensitivity to glare particularly at night.
Spectacles can help for the time but at a stage where it affects normal active life, surgical procedure to remove the lens can be performed by an eye specialist, procedure which is painless and 95% effective to restore your vision.
