Cataracts
A cataract is a clouding of the lens of the eye that affects vision. Most cataracts are related to aging.
By age 80, more than half of all North Americans either have a cataract or have had cataract surgery. A cataract can occur in one or both eyes.
Cataract symptoms
Because cataracts are a condition that worsens over time, so do its symptoms. The most common symptoms of a cataract are:
- Cloudy or blurry vision
- Faded appearance of colours
- Glare: headlights, lamps, or sunlight may appear too bright (a halo may appear around lights)
- Poor night vision
- Double vision or multiple images in one eye
- Frequent prescription changes in your eyeglasses or contact lenses
These symptoms can also be a sign of other vision problems. If you have any of these symptoms, it is recommended that you consult your eye care professional.
