The main way to protect your eyesight is to develop good eye habits and to correct or treat any vision abnormalities promptly.
Developing good eye habits is the main way to protect your eyesight. Don’t read in the environment with too much light or too dark, don’t read in the swaying car or boat, and don’t look directly at the luminous body with too much light. Do not avoid excessive eye use, do not use your eyes for a long time at close range, do not look at things upside down, reading and writing posture should be correct, often participate in outdoor sports, and look at the green mountains and green water more often.
After the occurrence of visual fatigue need to relax for a period of time. Vision abnormalities should be promptly checked for refractive errors, or eye diseases such as glaucoma, cataracts and vitreous hemorrhage. Early detection and treatment will prevent further vision loss.
