With increasing age, wisdom increases and vision decreases. This may not sound that unpleasant to many but the experience of compromised vision is awful for the people in advanced age groups.
The most common cause of this visual handicap is the cataract. It leads to the highest number of blinding cases globally. As per National Eye Institute survey, the cases of cataract blinding are on a steady rise. In the year 2000, there were 20.48 million people suffering from cataract in the us alone. This figure has risen by a whopping 20% in a decade taking the total to 24.41 million people in 2010. As per future projections around 50 million people would be suffering from cataract blindness by the year 2050.
Cataract- the silent enemy
Cataract in the eyes develops and progresses silently. Slowly and gradually with the advancing age, people start facing problems in visibility. The lens of the eye becomes cloudy or opaque. The problem begins with a blurry or foggy vision and the visibility deteriorates with time.
The biggest reason people do not pay attention towards it is that usually the cataract is painless and causes no discomfort to the victims. People just keep changing their eye-glasses for getting better vision and the cataract keeps expanding its reign in the eyes.
It is very important that patients familiarize themselves with the cataract symptoms. If people start seeking early cataract treatment, its impact will be low.
