A cataract is the clouding of the lens of the eye. A cataract
is apparent within the lens (nucleus, cortex and capsule)
when the nucleus becomes opaque or when small opacities develop
in the cortex, blocking or scattering light.
Effects of Cataract
- Blurred distance vision, especially outdoors.
- Headlights and stoplights appear to have streaks or halos.
- Discomfort Glare Sensitivity
- Veiling Glare Sensitivity
- Decreased Contrast Sensitivity
- Reading ability is impaired because print appears faded
and lacks contrast.
- Color distinction is impaired, blues appear green and
yellow appear white.
