1. Staring at the screen all day. The survey found that most people spend 400 minutes staring at computers, smartphones and televisions every day. Studies have shown that during this period, the number of blinks will be reduced by nearly 70%. Blinking too few times can cause sore eyes. At the same time, reading on the screen will make your eyes work harder, because digital pictures and texts are made up of tiny dots, which are not as clear as physical characters on printed pages. Over time, readers will suffer from "digital eye fatigue", which will lead to decreased vision and blurred vision.
2. Wear contact lenses for too long. The longer you wear contact lenses, the more dust, mucus, protein and minerals accumulate on the lenses. In addition to blurred vision, these sticky substances can also cause eye damage, such as dry eyes and inflammation and pain. A simple test method is to take off contact lenses and put on frame glasses. If the vision becomes clear, the contact lenses need to be cleaned or replaced. In hot summer and windy spring, it is best to wear less contact lenses.
3. Corneal abrasion. Usually caused by trauma, the symptoms are blurred vision, red eyes or foreign body sensation. In this case, you should see an ophthalmologist in time. A slight scratch will heal itself in a few days. If the condition is serious, the doctor will prescribe antibiotic eye drops to prevent infection or steroid eye drops to reduce inflammation and scar formation, which may lead to permanent vision loss.
4. Pregnancy. Changes in visual function, such as blurred vision and diplopia, are common during pregnancy. This is because the change of hormone secretion in the body will cause the fluid behind the cornea to change, change the shape and thickness of the cornea, and form transient myopia or hyperopia, which will not return to normal until after delivery. Therefore, we should pay attention to the habit of using eyes during pregnancy and one month after delivery, so that our eyes can get a full rest.
Hormonal changes caused by oral contraceptives and hormone replacement therapy may also affect vision. In addition, certain diseases (such as rheumatoid arthritis and diabetes) will also increase this risk.
5. Take some medicine. Antihistamines, antihypertensive drugs or antidepressants may cause dry eyes and blurred vision, because they will slow down the production of tears, or change their composition, causing tears to evaporate too quickly. Generally, it will get better after stopping the drug. If the problem is serious, you need to find a doctor to adjust the medication plan.
6. Got glaucoma. This disease is like an "invisible killer", but its attack on the eyes is quite powerful. When vision changes, many people have permanently lost some of their visual functions. Glaucoma is not only the "patent" of the elderly, but also the risk of onset at any age. People over 40 years old, with family history of glaucoma, diabetes, hypertension and high myopia are all high-risk groups of glaucoma. Therefore, it is very important to check your eyes regularly. /kloc-people aged 0/8 ~ 60 should be examined at least once every two years, and people over 60 should be examined once a year.

2. Looking farther can broaden your horizons and help you recover your vision. You also need to do necessary eye exercises to relieve eye fatigue.
