Do your eyes jump a few times a second over a period of time? A jumping eye can happen to anybody at any time. There are several reasons for a jumping eye. Let's have a look at it!
Tiredness Not getting enough sleep or working for too long without rest may cause our eye to complain. Scientists aren't sure why, but they've found that getting more rest will make our eyes feel better. Remember not to stay up late. |
Dry eyes More and more people work office jobs that require a lot of sitting and staring at a computer screen. This unhealthy way of life can lead to dry eye syndrome (DES干眼症) When our eyes are too dry, they can't help jumping to keep them wet. To stay away from DES, use eye drops if you use the computer for more than seven hours a day and make sure to look away from the screen once every 20 minutes. |
Stress(压力) This is the number-one reason for a jumping eye. It does harm to our eyes if it lasts for too long. When we' re under a lot of stress, the body gives out stress hormones (荷尔蒙) which leads to a “fight or flight” response. To solve the problem, we can see our friends or relax ourselves In order to reduce the stress that might lead to jumping eyes. |
First Aid: Nosebleeds Keep calm and stay in a safe place. Press both sides of the nose while the patient sits and leans (倾斜) forward. If bleeding continue, press harder until bleeding stops. Call 120 for help if:— Bleeding doesn't stop in 15 minutes. — Bleeding is heavy. — The patient has trouble breathing. |
