Patient discussion about blind

Q. Why is the color draining from my eyes?! When I was little I had rich shiny cobalt blue eyes! As I grew up they faded or just started to dim in color. Being partially blind you can see in my left eye the its a really light color and creamy instead of my deep blue color... Why does my eye color dim?! I didnt think going blind had anything to do with the color of my eyes changing... Or is it something else?! Please, and thank you!

A. depends on your blindness, if it is caused by your cornea changing (corneal opacity)- it'll change your eye color to a cloudy white. it can also be caused by cataract.
are those the reason of your blindness?

The Blind Girl turned immediately, and held her by both hands.
The Blind Girl still, upturning the blank sightless face, down which the tears were coursing fast, addressed her in these words:
I am not as blind as you think; gold and diamonds light up my night, the night of the last Facino Cane, for my title passes to the Memmi.
