Why does my vision seem cloudy, and why does my prescription keep changing?

Our eye functions much like a camera. The natural lens focuses images onto the back of the eye so we can see clearly, much like the lens of a camera focusing images onto film for a clear picture. At birth, our natural lens is clear, but as we age it yellows and hardens. In addition, the lens may become cloudy. This condition is called a cataract, and is usually a result of the natural aging process. As the lens becomes cloudier, vision becomes more blurred.

What symptoms might you notice with a cataract?

  • Dimming or blurring of vision
  • Halos or glare around lights
  • Double vision
  • Colors appear less brilliant
  • Feeling of “film” over the eyes
  • Frequent changing or cleaning of glasses
  • Difficulty driving or reading
