Cataract is the clouding in the eye lens as we age up. These
clouds develop slowly and over time may cause full blindness to
patient. So the treatment of cataract is necessary as soon as
possible. As cataract increases, the vision of eye lessens,
because the cloud stops the light to pass through the lens and
reach the retina. Cataracts are divided into four categories on
the basis of its cause – Radiation, secondary, congenital and
traumatic cataracts. Different types of cataracts - Secondary
cataract: These are cataracts that are formed after surgery due
to glaucoma, due to diabetes or due to use of some steroids. -
Traumatic cataract: cataract caused by an eye injury. -
Congenital cataract: Some cataracts can be genetic and children
may be born with small cataracts. But they don’t affect the
vision, and if they do then the eye lens should be replaced as
soon as possible. - Radiation cataract: Exposure to radiation
can also cause cataract. Symptoms of cataracts - Yellowing or
fading of colors - Halos or glow
