Can Cataracts Develop Faster in One Eye Than the Other?

Cataracts are a common age-related eye condition that occurs when the natural lens of the eye becomes cloudy, leading to blurry vision, glare, or difficulty seeing at night. While many people expect cataracts to affect both eyes equally, it’s not uncommon for one eye to develop a cataract more quickly than the other.

Why Cataracts Progress at Different Rates

Cataracts typically develop slowly, but their progression can vary between eyes. Several factors may contribute to one eye being more affected:

• Age and Natural Changes - While aging is the most common cause, the rate at which proteins in the lens break down can differ between the eyes.

• Sun Exposure - If one eye is more exposed to sunlight over time, UV damage can accelerate cataract development.

• Eye Injury or Surgery - Trauma or past procedures on one eye can increase the risk of an earlier or faster-developing cataract in that eye.

• Medical Conditions - Diabetes and certain medications, like long-term steroid use, may influence how quickly cataracts form in each eye.

• Genetics - Family history can play a role in how and when cataracts progress.

Signs You May Notice an Imbalance

If one cataract progresses faster than the other, patients often report:

• Clearer vision in one eye compared to the other

• Increased glare or halos in one eye, especially at night

• Double vision or shadowing

• Needing to cover one eye to read or watch TV comfortably

These differences can create frustration, as the brain struggles to balance the visual input from each eye.

What You Can Do

The best way to monitor cataract progression is through regular eye exams. An optometrist can track changes in each eye and recommend the right time for cataract surgery, if needed. Even if only one eye is significantly affected, surgery may be recommended to restore balance and improve overall vision.
