Contact Lenses and Cataracts: What You Need to Know

What is Cataract?

Cataract is a condition that affects the lens of the eye, causing it to become cloudy and opaque. This cloudy lens can cause vision problems, such as blurry or dim vision.

Can Wearing Contact Lenses Cause Cataracts?

The short answer is no. Contact lenses cannot cause cataracts. However, research suggests that people who wear contact lenses may be at a slightly higher risk of developing cataracts.

Why Might Contact Lens Wearers be at a Higher Risk of Developing Cataracts?

One theory is that contact lenses can cause micro-trauma to the surface of the eye. This trauma can lead to inflammation and oxidative stress, both of which are thought to be involved in cataract formation.

What Can You Do to Reduce Your Risk of Cataracts?

There are several things you can do to reduce your risk of developing cataracts. These include:

  • Wearing sunglasses to protect your eyes from UV radiation
  • Eating a healthy, balanced diet that includes plenty of fruits and vegetables
  • Avoiding smoking and excessive alcohol consumption
  • Getting regular eye exams to catch and treat cataracts early

Can Contact Lenses Affect Cataract Surgery?

If you do develop cataracts and need surgery to remove them, wearing contact lenses may affect your surgery and recovery. Your eye doctor will likely advise you to stop wearing your contact lenses before your surgery and for a period afterward. This is to allow your eye to heal properly and reduce the risk of infection.


While wearing contact lenses won’t directly cause cataracts, it’s still important to take care of your eyes to reduce your risk of developing this common eye condition. By following the tips above, you can help keep your eyes healthy and reduce your risk of cataracts. And if you do develop cataracts, talk to your eye doctor about the best options for treatment and recovery.
