Cataracts 101: What You Need To Know

Many things make cataracts a tricky problem, and a lack of knowledge about what they are, and how they form, complicates matters even further.

Let’s start with what they are. Cataracts are a cloudy area in the eye’s lens, which is located inside the eye behind the pupil, that blocks the passage of light through it to the retina. Because they interfere with how the retina processes light, they can cause vision problems.

Cataracts don’t hurt, so most people don’t know they are developing them until the condition is fairly advanced. Here are some symptoms that are signs of cataract development:

  • Cloudy, fuzzy or foggy vision
  • Glare from lamps or the sun, or from car headlights at night
  • Frequent eyeglass-prescription changes
  • Double vision in one eye

Any or all of these are good reasons to make an appointment with your eye doctor. He or she can quickly run some tests during the course of a routine examination to see if you’re developing, or have developed, cataracts. If that’s the case, then there are routine surgical procedures that will clear up the problem quickly.
