The Different Types of Cataracts

cataracts

Cataracts are a clouding or yellowing of the usually transparent lens, located directly behind the iris. The lens must be clear to focus light onto the retina. However, certain factors can cause a cataract to form, decreasing the eye’s ability to focus. Early diagnosis and treatment by an experienced ophthalmologist are essential for preventing permanent vision loss.

Symptoms:

  • Double vision
  • Light sensitivity
  • Poor night vision
  • Need for brighter reading light
  • Changes in the way you see color
  • Cloudy, blurry, foggy, or filmy vision
  • Visible glare or haloes, particularly at nighttime
  • Prescription changes for eyeglasses or contact lenses

Although the following are not meant to be exhaustive, here are three reasons for the formation of cataracts, with the most common being age. If you are experiencing any noticeable impairments in vision, please contact the Eye Physicians of North Houston to schedule an appointment for a comprehensive, dilated eye exam.

Age-Related Cataracts

Most cataracts result from natural changes with age. According to the National Eye Institute, the protein in the lens of your eye begins to break down and form clumps, usually after your fortieth birthday. A buildup of proteins alters the ordinarily transparent lens into a cloudy structure called a cataract. Half of all adults will have developed a cataract by the time they are 80.

Exposure to Radiation

Another cause of cataracts is long-term exposure to specific radiation types. The sun’s ultraviolet rays are one such type. The American Academy of Ophthalmology recommends wearing sunglasses that block 99 or, even better, 100 percent of all harmful UV light while outdoors. Radiation therapy can also result in their formation.

Eye Injuries or Infection

An experienced ophthalmologist should always examine eye injuries. That is especially true since eye injuries can damage the lens, potentially causing a cataract to form or impacting your vision in other ways, such as causing infection. The best way to prevent eye injuries, especially if you are around flying debris or working with chemicals, is to wear protective eyewear. They should also be worn when performing certain recreational activities.
