Some people believe cataracts to be a form of color blindness,
but they are not. Cataracts are a clouding that develops on the
crystalline lens of the eye, and the effect is to cloud vision.
Color vibrancy is definitely reduced with cataracts, hence the
common misconception that it is a form of color blindness.
However along with vibrancy, clarity is also reduced in line
with symptoms of short sightedness etc. Rather than a genetic
mutation of a gene or a defect in the shape or structure of the
eye, cataracts are instead a disease that disables correct
vision by obscuring incoming light waves. As a cataract
strengthens, vision quality will be compromised in a few ways. A
person will lose sensitivity to color contrast causing contours,
shadows, and colors in general to become less vivid. A cataract
scatters light as it enters the eye, causing a veiling glare
over someone’s vision. Early signs of cataracts are typically
seeing a halo around bright lights at night – for example street
