Overview

Presbyopia is the medical term for your eye losing the ability to change its focus. This affects how well you can see close-up objects. It occurs as your eye’s natural lens grows less flexible with aging.

Presbyopia generally starts to develop around age 40 and gets worse until your mid-60s. You’ll notice that reading or other close-up tasks are harder than they used to be. You might need to hold your book or phone out at arm’s length to see the words clearly. You may also have symptoms like headaches or sore, tired eyes.

Presbyopia is part of the natural aging process, and it’s not a disease. It’s a common type of refractive error that eye care specialists can easily correct with glasses, contacts or surgery.

How common is presbyopia?

Presbyopia is very common. Globally, about 1.8 billion people had presbyopia in 2015. Researchers estimate this number will rise to 2.1 billion by 2030.

Complications

Blood clots are a dangerous complication of atrial fibrillation (AFib). Blood clots can lead to stroke.
The risk of stroke from AFib increases as you grow older. Other health conditions also may increase the risk of a stroke due to AFib. These conditions include:
  • High blood pressure.
  • Diabetes.
  • Heart failure.
  • Some types of heart valve disease.
Blood thinners are commonly prescribed to prevent blood clots and strokes in people with atrial fibrillation.

Prevention

Healthy lifestyle choices can reduce the risk of heart disease and may prevent atrial fibrillation (AFib). Here are some basic heart-healthy tips:
  • Control high blood pressure, high cholesterol and diabetes.
  • Don't smoke or use tobacco.
  • Eat a diet that's low in salt and saturated fat.
  • Exercise at least 30 minutes a day on most days of the week unless your health care team says not to.
  • Get good sleep. Adults should aim for 7 to 9 hours daily.
  • Maintain a healthy weight.
  • Reduce and manage stress.
