Can You Have a Cataract in One Eye?

While cataracts are often associated with aging and typically affect both eyes, it is entirely possible for a cataract to develop in only one. Understanding how cataracts form, who is at risk, and the importance of regular eye exams can help you stay informed and protect your vision.
 

What Are Cataracts?

A cataract occurs when the clear lens inside your eye becomes cloudy, making it harder to see clearly. This clouding is typically caused by a breakdown of proteins in the lens, which clump together and obstruct light from passing through normally. As cataracts progress, they can lead to blurred vision, glare, difficulty seeing at night, and faded colors.
 

Understanding How Cataracts Develop

Cataracts usually develop gradually, and in many cases, they begin forming in both eyes. However, the rate at which cataracts develop can differ between eyes, leading one eye to experience more noticeable symptoms sooner.In some situations such as an eye injury, surgery, radiation exposure, or specific medical conditions, a cataract may only develop in one eye. This is known as a unilateral cataract. While it is less common than bilateral cataracts, it is still a condition that requires attention and proper management.
 

Who Is at Risk for Cataracts?

Cataracts are most commonly associated with aging, typically beginning to develop around age 40 and becoming more pronounced after age 60. However, several other factors can increase your risk:
 

• A history of eye injuries or surgeries
• Diabetes or other chronic health conditions
• Smoking
• Prolonged exposure to sunlight without UV protection
• Use of corticosteroid medications over time
• Excessive alcohol consumption
• Family history of cataracts

Even children can be born with congenital cataracts or develop them early in life due to genetic factors or infections.
 

The Importance of Routine Eye Exams

Regular eye exams play a crucial role in the early detection and treatment of cataracts - whether in one eye or both. Since cataracts progress slowly, many people do not notice changes in their vision right away. A comprehensive eye exam can detect signs of cataracts long before they start to impact your daily life, allowing your optometrist to monitor their development and recommend treatment when necessary.
