Cataracts are characterized by a gradual clouding of the eye’s natural lens, leading to a slow decline in vision over time. One of the most common symptoms is blurred or cloudy vision, often described as looking through a foggy or dusty window. Colors may appear faded or yellowed, and there can be increased sensitivity to light and glare, particularly from sunlight or oncoming headlights at night. People with cataracts often see halos around lights and may struggle with poor night vision. Another telltale sign is the frequent need to change eyeglass or contact lens prescriptions, along with occasional double vision in one eye. Reading, driving, and recognizing faces can become more difficult as the cataract progresses. While cataracts usually develop with age, they can also be caused by factors such as diabetes, eye injuries, long-term use of corticosteroids, or prolonged exposure to ultraviolet (UV) rays.
