Continuing
in our serieson Cataracts, here’s the next installment. You can get more details in the original
article at www.allaboutvision.com/conditions/cataracts.htm
Cataract Symptoms and Signs
A cataract
starts out small and at first has little effect on your vision. You may notice
that your vision is blurred a little, like looking through a cloudy piece of
glass or viewing an impressionist painting.
The improved
vision is short-lived and will disappear as the cataract worsens. On the other
hand, a subcapsular cataract may not produce any symptoms until it's
well-developed.
What Causes
Cataracts?
The lens inside
the eye works much like a camera lens, focusing light onto the retina for clear
vision. It also adjusts the eye's focus, letting us see things clearly both up
close and far away. Many cataracts are caused by oxidative changes in the human
lens. This is supported by nutrition studies that show fruits and vegetables
high in antioxidants may help prevent certain types of cataracts
