WHAT IS A CATARACT?
What is a Cataract?
A cataract is a clouding of the eye’s natural lens, which lies behind the iris and the pupil. It is a common condition that often develops with age but can also result from trauma, exposure to certain chemicals, or diseases like diabetes. When a cataract forms, it scatters and blocks light as it passes through the lens, preventing a sharp, clear image from reaching the retina. This results in blurred vision, faded colors, and increased glare from lights, significantly impacting daily activities such as reading, driving, and recognizing faces.

Types of Cataracts
Over 24 million adults across the United States contend with cataracts, a prevalent concern among individuals aged 60 and above. Age-related cataracts, the most widespread variant, gradually emerge as the eyes undergo natural aging processes, primarily affecting the central region of the lens. Termed nuclear cataracts, they manifest as a progressive clouding or blurring of vision.
In addition to nuclear cataracts, other forms can impact vision differently. Some develop along the edges of the lens, while others arise at the rear. Notably, cataracts affecting the posterior part of the lens often exhibit swifter progression compared to their counterparts.
Distinct varieties of cataracts include nuclear, cortical, and posterior subcapsular. Nuclear cataracts form centrally, tinting the lens brown over time. Cortical cataracts initiate at the periphery, gradually encroaching towards the center. Meanwhile, posterior subcapsular cataracts emerge on the rear surface of the lens.
Cataracts Evolve Gradually
While many cataracts evolve gradually, some individuals may remain unaware of their presence until clarity diminishes, particularly in low light conditions. However, posterior subcapsular cataracts typically advance rapidly, leading to common symptoms such as glare from bright lights and halos around light sources during nocturnal hours. Regardless of type, all cataracts can significantly impair vision and disrupt daily activities.
