Simple lifestyle modifications can help keep your vision sharp.

You Will Need

An eye-care professional
Fruits and vegetables
UV-protective sunglasses
Family medical history

Step 1: Have a comprehensive dilated eye exam（给眼睛一次专业的检查）
Have your eyes checked under dilation by an eye-care professional.

Step 2: Eat a healthy diet（多吃蔬菜和水果）
Include plenty of fruits and vegetables in your diet. Dark leafy greens and foods rich in omega-3 fatty acids, like olive oil and flax seed, contribute to good eye health.

Step 3: Watch your weight（均衡自己的体重）
Maintain a healthy weight. Being overweight raises your risk of developing diabetes, which can cause vision loss.

Step 4: Don’t smoke（不抽烟）
Avoid smoking, which has been linked to several diseases that can cause blindness.

Step 5: Wear sunglasses outdoors（出门带太阳镜）
Protect your eyes from the sun’s ultraviolet rays with sunglasses.

If you work at a computer, reduce eyestrain by looking off in the distance every 20 minutes for approximately 20 seconds.

Step 6: Pay attention to your family history（注意家族的眼睛史）
Determine whether you are at risk of developing a hereditary eye disease by tracking your family’s health history.
