The most common symptom of
cataracts is seeing blurry
images at any distance.
People may describe their vision as
foggy, cloudy, or filmy.
Cataracts get worse with time, and less
light reaches the retina.
It may be especially hard for people
with cataracts to see and drive at night.

Glare, or sensitivity to light, is
another symptom of cataracts.
It can be difficult for a
person with cataracts to see
in bright sunlight.
Indoor lights may begin to seem
too bright,or they may appear to
have halos around them.
Glare from oncoming headlights can
cause problems with driving at night.

Diplopia, or double vision, when
looking with one eye can be
another symptom of cataracts.
This is not the same as diplopia
that arises from improper
alignment of the eyes.
The double vision seen with
cataracts occurs even when you
look through only one eye.

Cataracts also affect color vision.
Some colors may appear faded, and
things may acquire a yellowish
or brownish tint.
This may not be noticed at
first,but with time,
distinguishing between blues
and purples can be dificult.

In this situation, the cataract
acts as a stronger lens,
temporarily improving the ability to
see things at a close distance.
People who formerly needed reading
glasses may no longer need them.
However, as the cataract worsens over
time, this temporary improvement
in near vision disappears.

People with cataracts often need
frequent changes in their eyeglasses
or contact lenses because their
vision deteriorates over time.
