Overview
Symptoms of a Cataract
Cataracts are a progressive condition in which the lens of the eye becomes cloudy and grows increasingly opaque. They are usually white, but can be tinted yellow or brown. As a result, the symptoms vary, depending upon the type and severity of the cataract.

When there is only a hint of cloudiness to the lens, the cataract is classified as "trace." As the cloudiness progresses, the cataract may be classified as "mild" to "moderate." Once the cloudiness becomes very pronounced, the cataract is classified as "mature."

As the cataract becomes progressively cloudy, it blurs and distorts vision to an increasing degree. Vision with a cataract is similar to peering through a dirty or frost covered window. As the dirt or frost on the window increases, it becomes more difficult to see a clear image. As the cataract grows more opaque, images become less recognizable. Ultimately, the cataract may become so dense that it blocks light from entering the eye, resulting in needless blindness.

Cataracts are not always white in color. If they assume a yellow or brown tone, they will affect the ways colors appear. This is similar to the way colored lenses in a pair of sunglasses alter colors.

Because cataracts develop at a slow pace, the changes they cause in vision occur slowly. Due to their progressive nature, the symptoms become more pronounced over time.

Common Symptoms

• A gradual deterioration in vision over time
• Objects may appear yellow, hazy, blurred or distorted
• Vision at night or in low light conditions may be dramatically reduced
• Vision in bright light or in the sunshine may be difficult due to glare
• Halos may appear around bright lights at night.
  

Lifestyle Limitations Due To Cataracts
Because cataracts cause a blurring or distortion of vision, as well as decreased vision in low light conditions, they have a dramatic impact upon one's lifestyle. Some limitations due to cataracts include the following:

• Inability to read or watch television
• Inability to drive (Poor eyesight due to cataracts is the leading reason older adults lose their driver's license.)
• Lack of desire to go out at night
• Loss of independence
• Increased chances of injury due to impaired eyesight.
  

Fortunately, microsurgery offers a simple and effective way of restoring vision lost due to cataracts. Once the cataract is removed, vision almost always improves, and so, too, does the quality of life for most patients.
