The average tear film rupture time is 6.3 seconds (the normal value of tear film rupture time is 15-45 seconds, less than 10 seconds is pathological).

It is a habit to play with the cell phone before going to bed, without thinking about it. After going to bed and turning off the lights, you are still using your smartphone. The strong light of cell phone shines directly on your eyes for more than 30 minutes, causing macular lesions in your eyes, resulting in rapid deterioration of vision, especially irreversible macular disease. Once you have macular disease, it is equal to eye cancer, only waiting for blindness, because modern medicine can not treat, let alone cure. Turning off the lights to look at the cell phone screen in the dark is particularly bright, close viewing, high energy directly into the eye, directly harming the macula of the eye. Physicians said that macular degeneration is mostly a symptom of the elderly, but recently there is a trend of younger patients. Most of them are heavy smartphone users. Please note: when the lights are off, whether it is looking at the phone, or slide the tablet, not only macular lesions, the initial stage will lead to dry eye disease, serious cataracts will report early, and even loss of vision, becoming blind. In the early stage of the disease, you have to receive laser or steroid injection to have a chance to cure. The doctor suggested that in addition to supplementing lutein, the most important thing is to quit the bad habit of using cell phones. Because you can’t help slipping before going to bed, I’m afraid it will cause a lifetime of damage. Friends: For the sake of yourself and your family, remember not to look at your cell phone in low light and after the lights are turned off, especially children should not play with their cell phones. So what exactly are the ways to help children quit IPad phones? Let’s take a look through an example! Andy, a young boy, is also an Ipad control, playing with the iPad can often do not drink water and do not eat, in the experience of a time due to play Ipad obsession from the family’s stairs rolled down and broke a leg, the mother made the following move: summer vacation one day, the bear child as usual to get up, after breakfast to play Ipad, surprisingly found Ipad above a small note: Mom from today onwards to implement If you don’t accept the new rules, you have the right to refuse, but your pad will be given to your cousin Jenny the day after tomorrow. After 2pm, you missed the chance to get the password, now go clean your little desk first! Dumbfounded, Andy was angry and annoyed, but his mother was not at home, and his heart was crawling like an ant. When he cleaned up the messy books on top of the desk, he found another note stuck to the desk: That’s nice, after one chore, please mop up the floor! The boy fetched a bucket of water, picked up the mop and mopped the floor. As he crept on the floor, he found another note taped to the bottom of the couch: Go for it, mommy saw your effort! Throw away the kitchen trash and you’ll find the code. When the little boy picked up the kitchen garbage bag and threw it into the garbage can on the street, he saw a line of captions similar to the password on the side of the can, and it was his mother’s handwriting! No wonder the mom said it would be invalid beyond 2pm because the community garbage truck comes to collect the garbage at 2pm every day! I have to praise this mom’s new rule, which not only limits the children’s Ipad playing to a certain extent, but also makes them develop good habits of doing housework. As it turns out, after just one week, Andy became less enthusiastic about the Ipad and his attention started to turn to playing basketball, which is a victory for homeschooling! Most of the attempts to stop children from playing with cell phones and Ipads, whether by reasoning or forcibly, end in failure because young children tend to be “forgetful” and reasoning is effective this time or next time, while forcible withdrawal is a direct consequence of children’s resistance and crying, and may even lead to children becoming stubborn. “You do not let play, I want to!”
