Types of Cataracts
Nuclear Cataracts
These are the cataracts that develop in the center of the lens . A person throw nuclear cataract may initially become more shortsighted and may even experience a temporary improvement in one ’s reading imaginativeness . However , as the time goes on , there is gradual dense yellowing of the lense , which clouds the vision further . atomic cataracts may sometimes lead in a affected role figure double or multiple double . As the cataract advances , there may be brown coloration to the lense . This advance phase of yellowing or browning of the lens causes the patient difficultness in specialize between ghost of color .
Cortical Cataracts
This type of cataracts dissemble the edge or the flange of the lens . A cortical cataract starts as a submarine sandwich - shaped , milky opacities or blot on the outer lip of the pallium of the lens . As the status advance , these dapple or opacities start to spread towards the center of the genus Lens resulting in difficulty of light go past through the lens system ’ center .

As a person ages , the lenses in the eyes fall back its flexibleness , transparence and becomes thicker . Other age link changes of the electron lens have partitioning and clumping of the tissues together result in clouding of small region of the crystalline lens .
