Cataracts start small and affect only a minor part of the lens at first. Therefore, most people have no idea that a cataract is present. Often, only one eye is involved in the beginning. Your ability to see things close up or far away will be affected depending on where the cataract is located. The change may be most obvious at night, or you may notice it more in bright daylight. After months or years, your cataract will grow to cover more of the lens, affecting a greater part of your range of vision.

Common signs and symptoms of cataracts are listed below. However, these symptoms can also be signs of other eye problems. If you have any of these symptoms, you should schedule a check-up with your eye doctor.

  • Cloudy, blurry, or dim vision
  • Poor night vision or increased difficulty seeing in the dark
  • Sensitivity to light and glare (including car headlights, lamps, or sunlight)
  • "Halos" appear around lights
  • A need to change eyeglass or contact lens prescriptions more often
  • Faded or yellowing colors
  • Double vision or multiple images in a single eye (this symptom may disappear as the cataract grows). 
If you notice any changes in your vision, have an eye check-up right away. Sudden vision changes, such as double vision or blurring, require an immediate appointment with your healthcare provider.
