What is Cataract?
[[File:Cataract in human eye.png|thumb|A cataract in a human [[eye]]]] A '''cataract''' is when the [[lens (eye)|lens]] of the [[eye]] gets cloudy. It is a [[treatable medical condition]]. Cataracts can cause short-sightedness ([[myopia]]), which means you cannot see things in the distance but can see things up close. If not fixed by [[surgery]], some types of cataracts will cause [[blindness]] (which means you cannot see anything at all). In a simple [[operation]], the old lens can be replaced by a new plastic one. Many thousands of people have had this operation. == Signs and symptoms == Cataracts develop gradually over time, so symptoms may not be immediately noticeable. However, as the condition progresses, the following signs and symptoms may become apparent: # '''Cloudy or Blurry Vision''': This is one of the most common symptoms of cataracts. Vision may become increasingly cloudy, hazy, or blurry, making it difficult to see clearly. # '''Sensitivity to Light''': Individuals with cataracts may experience increased sensitivity to bright lights, glare from headlights, lamps, or sunlight. # '''Fading or Yellowing of Colors''': Colors may appear faded or less vibrant than usual. Some people with cataracts also experience a yellowing or browning of colors. # '''Poor Night Vision''': Cataracts can cause difficulty seeing in dim or low-light conditions, which may result in problems with night driving or navigating in darkened rooms. # '''Frequent Changes in Eyeglass Prescription''': As cataracts progress, changes in vision may necessitate frequent changes in prescription eyeglasses or contact lenses. # '''Double Vision''': Cataracts can cause double vision in one eye, which may disappear when the affected eye is closed. # '''Halos Around Lights''': Some individuals with cataracts may see halos or circles around lights, particularly at night. # '''Difficulty with Reading and/or Watching Television''': Cataracts can make it challenging to focus on close-up tasks like reading or watching television. # '''Increase
