Know Before You Go: The Three Types of Cataracts
Understanding the Three Types of Cataracts
Cataracts, a common cause of vision loss, occur when the lens of the eye becomes cloudy due to a buildup of proteins. Left untreated, cataracts can lead to significant vision impairment or blindness. There are three primary types of cataracts, each affecting the lens differently: nuclear sclerotic, cortical, and posterior subcapsular cataracts.
1. Nuclear Sclerotic Cataracts
Nuclear sclerotic cataracts are the most common type. They develop gradually and primarily affect the central zone of the lens, known as the nucleus.
Key Features:
2. Cortical Cataracts
Cortical cataracts form in the outer shell of the lens, known as the cortex, and spread inward like spokes on a wheel.
Key Features:
3. Posterior Subcapsular Cataracts
Posterior subcapsular cataracts form on the back surface of the lens, beneath the lens capsule—a thin membrane that holds the lens in place.
Key Features:

There are three primary types of cataracts, each affecting the lens differently: nuclear sclerotic, cortical, and posterior subcapsular cataracts.
1. Nuclear Sclerotic Cataracts
Nuclear sclerotic cataracts are the most common type. They develop gradually and primarily affect the central zone of the lens, known as the nucleus.
Key Features:
- Begins with hardening and yellowing of the nucleus.
- Progresses over time, spreading to other layers of the lens.
- Can temporarily improve close-up vision (a phenomenon called "second sight"), but this effect is short-lived.
- Progression is typically slow, taking years before vision is significantly affected.
2. Cortical Cataracts
Cortical cataracts form in the outer shell of the lens, known as the cortex, and spread inward like spokes on a wheel.
Key Features:
- Causes light to scatter, leading to blurred vision, glare, and reduced contrast and depth perception.
- Often linked to diabetes, increasing the risk for those with the condition.
- Symptoms become more noticeable as the cataract progresses toward the center of the lens.
3. Posterior Subcapsular Cataracts
Posterior subcapsular cataracts form on the back surface of the lens, beneath the lens capsule—a thin membrane that holds the lens in place.
Key Features:
- Affects reading and night vision early in its development.
- Causes glare and halos around lights, especially at night.
- Progresses more quickly than other types, with symptoms becoming noticeable within months.
- Risk factors include diabetes, steroid use, extreme nearsightedness, and retinitis pigmentosa.
