如何使眼睛保持健康 How to Keep Your Eyes Healthy

如何使眼睛保持健康
Simple lifestyle modifications can help keep your vision sharp.
Steps 步骤
STEP 1 Have a comprehensive dilated eye exam 做全面的眼科检查
Have your eyes checked under dilation by an eye-care professional. 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 关注自己的体重
Maintain a healthy weight. Being overweight raises your risk of developing diabetes, which can cause vision loss.
STEP 4 Don’t smoke 不要吸烟
Avoid smoking, which has been linked to several diseases that can cause blindness.
STEP 5 Wear sunglasses outdoors 在户外时戴墨镜
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 关注自己的家族病史
Determine whether you are at risk of developing a hereditary eye disease by tracking your family’s health history.
Did you know? By age 65, one in three persons has a vision-impairing condition. By age 80, the percentage climbs to 50 percent.
