Are Cataracts Hereditary? Understanding Risk Factors

Cataracts are a gradual clouding of the eye's clear lens, causing blurred vision and difficulty seeing at night. Over time, the symptoms of this condition worsen and cause more serious vision problems, including light sensitivity, worsening eyesight, the appearance of halos around lights, faded colors, and even double vision. Cataracts tend to develop in response to age-related changes in the eye, but are cataracts hereditary?

Risk Factors for Cataracts 

Although those who have a family history of cataracts are more likely to develop this condition, other risk factors also contribute. Cataracts are more common among people who are older than 60, are obese, smoke, have diabetes or high blood pressure, have been exposed to UV rays without eye protection, had a previous eye injury or surgery, drink alcohol excessively, or use corticosteroid medications. Keep in mind that cataracts are a very common condition, and they are even more common among those with a family history. According to the American Academy of Ophthalmology, more than half of Americans develop a cataract in at least one eye by age 80.

Preventing Cataracts

While it's impossible to influence a family history of cataracts, controlling other risk factors can help keep the eyes healthy. The following are some preventive measures to take:

• Quitting smoking
• Limiting alcohol to no more than one drink a day
• Having regular eye exams
• Managing chronic conditions like hypertension and diabetes
• Eating a nutritious diet with plenty of fruits and vegetables, particularly those rich in antioxidants such as berries and leafy greens
• Wearing sunglasses with UV protection when outdoors

Treatment Options for Patients With Cataracts

Those that are experiencing blurred vision and light sensitivity due to cataracts can dramatically improve their quality of vision through cataract surgery. The eye surgeon will remove the affected lens and replace it with a clear intraocular lens (IOL) implant to restore sight and reduce symptoms like blurriness. Cataract surgery is typically an outpatient procedure done under local anesthetic. Patients can return to normal activities within a day or two.
