What is cataract?Cataract
is one of the most common diseases of the eye that affects a sizable
section of the world’s population. Although most cataracts appear in
patients above 40 years of age, paediatric cataract is not a rare
phenomenon either. So what exactly is cataract and how does it affect
the eyes? Here’s all the information you’ll need.
Cataract - Is it because of your parents, your lifestyle or just bad karma?Cataract
is a disease that affects the lens of the eye. The human lens, like the
lens of a camera, focusses light on the retina (the camera film).
Typically, the human lens contains soluble proteins and water that are
arranged in a specific pattern to give the lens its transparent nature.
It is this transparency that enables light to pass through and focus on
the retina, to be picked up by the optic nerve to form an image of what
you see. As we grow old, the proteins start clumping together and
clouding the lens, and this is called Cataract. Besides ageing, cataract
can also develop due to exposure to UV rays, injury, prolonged use of
certain medications etc.
Did you know?In
earlier days, cataract was considered as a wrath of the Gods and seemed
to have a direct connection with one’s karma. In fact, there are quite a
few African countries that still believe so and engage in age-old and
unsafe practices like couching to remove cataract.
Cataract symptoms - common signs you just can’t missThe
symptoms of cataract largely depend on the type of cataract that’s
developing in the lens. Not all cataracts are alike. While for some
people, it develops in the center of the lens others could develop it
around the lens’ periphery while few others might have it at the back of
their lens. Some of the most common symptoms, however, are
blurry/clouded vision, sensitivity to bright light, dull appearance of
colours, change in spectacle prescription, etc. In case of paediatric
cataract, you’ll find that the kid does not react well to light or
colourful objects. If you notice one or more of these symptoms, please
visit your eye doctor and get a check-up done immediately.
