3 . Eyesight problems are common among all ages and if they are left untreated, they can cause serious headaches or other problems. The good news is that most eyesight problems can easily be sorted out by wearing glasses.
Regular eye tests are important for everyone. Children and teenagers, under the age of 16 and up to the age of 19 for those full-time education, have the right to have eye tests for free in Britain. As the eye test is free, there’s no excuse for not having a regular eye test. Doctors suggest that it’s better to have an eye test about once a year.
Wearing glasses isn’t always regarded as all that cool and teens who suddenly need to wear glasses may find it difficult to accept. If they’ve grown up wearing glasses, then they may be more used to it. However, if your eyes are in poor health, not wearing glasses can put even more pressure on your eyes and could make them even worse.
Thankfully, the days of little choice of glasses frames for teenagers are gone and there’s now a wide selection of frames. If a teen does need to wear glasses, then it’s good to let him or her choose the type, as he or she will be able to choose something he or she feels comfortable. Don’t forget to be guided by the experts on glasses, too.

4 . Ways to protect eyes from screens
Too much screen time may cause serious eye strain (眼疲劳) and even a sharp decline of eyesight. That's a big problem a lot of people are faced with nowadays, especially those who work on a computer. The following tips may be helpful.
Get regular eye tests
Experts recommend having a comprehensive eye exam every year to detect (探测) problems before they develop. During this test, you should tell the doctor how often you use your phone and your computer.
Give your eyes space
Take breaks
This may not always be practical if you're quite busy, but it's important not to stare directly at a screen for too long.
Staring at a screen continuously for hours on end may make it difficult for you to focus. To avoid this, many eye experts recommend the “20-20-20 rule” — looking away from your phone/computer screen every 20 minutes and focusing on an object at least 20 feet away for at least 20 seconds. The science behind his trick is that looking at objects at a distance relaxes the focusing muscle in the eye.
| A．Exercise your eyes. |
| B．Give your eyes a chance to rest. |
| C．Make your screen more eye-friendly. |
| D．Studies show it's an effective way to reduce tiredness. |
| E．You should also measure the distance from your eyes to your screen at work. |
| F．The closer your phone/computer screen is to your eyes, the harder they have to work to focus. |
| G．Make sure that you use your phone or computer in a room where the lighting is bright enough. |
5 . A new study, published this week in the journal Frontiers in Veterinary Science, reveals that non-human animals' tears are not so different from our own. The chemical similarities are so great, in fact, that the composition of other species' tears—and how they're adapted to their environments-may provide insights into better treatments for human eye disease.
Previously, scientists had studied closely only the tears of a handful of mammals, including humans, dogs, horses, camels, and monkeys. In the new study, Brazilian veterinarians analyzed the tears of reptiles and birds for the first time , focusing on seven species.
Tears, which are released from tear tubes, form a film over the eye that's composed of three ingredients: mucus, waler, and oil. The mucus coats the eyes surface and helps to attach the film to the eye, the water is a natural salty solution containing crucial proteins and minerals, and the oil prevents the eye from drying out.
Humans are the only known species to produce emotional tears; the expression "crocodile tears," which refers to a person's phony display of emotion, comes from the mysterious tendency of crocodiles to release tears as they eat.
But tears play key roles beyond weeping, notes Lionel Sebbag at Iowa State University, who was not involved in the new research. They help with vision by lubricating and clearing the eye. They also protect the eye against infection and provide nutrition to the cornea, the eye's clear outer layer, which lacks blood tubes, he says.
Learning how reptiles and birds' use tears may also inspire new medications for conditions such as dry eye, which occurs when tear tubes don't produce enough oil. The disease, common in cats, dogs, and people, can sometimes lead to blindness.

9 . When we say older people shrink,we don't mean they become tiny enough to fit in your pocket!We just mean that it's common for older people to become a little shorter over time.This kind of shrinking can't be stopped, although people can slow this process.But why does shrinking happen at all?
Because of gravity,cushions between the bones in the spine（脊骨）get compressed（压缩）,which makes a person lose a little height and become shorter.
Another reason why some older people shrink is because of osteoporosis（骨质疏松）.Osteoporosis occurs when bone is broken down and not enough new bone material is made.Over time,bone is said to be lost.Bones become smaller and weaker and can easily break if someone with osteoporosis is injured.
Older people—especially women,who generally have smaller and lighter bones to begin with—are more likely to develop osteoporosis.As years go by,a person with osteoporosis can get small breaks in bones that are called compression fractures.These breaks cause collapse of the spine and over time the person with osteoporosis can become hunched over（驼背）.
Did you know that every day you shrink a little,too?You aren't as tall at the end of the day as you are at the beginning.That's because as the day goes on,water in the disks of the spine gets compressed due to gravity,making you just a tiny bit shorter.Don't worry,though.Once you get a good night's rest,your body recovers,and the next morning,you're standing tall again!
Smoking and drinking alcohol can make this problem worse.Want to do something right now to build strong bones?I believe what I say will help you.

10 . Crossing your legs is an extremely common habit; most people don't even notice that they're doing it when they sit down. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.
A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason for this is that the blood in your legs has to work against gravity to be pumped back to your heart and that crossing one leg over the other increases resistance(阻力), making it even harder for the blood to circulate. This causes your body to increase your blood pressure to push the blood back to the heart. You won't feel any immediate effects, but repeated, drawn-out increases in blood pressure can cause long-term health problems. So, planning to sit for a long period of time? Don't keep your legs crossed.
Crossing your legs at the knee can also cause pressure on the major nerve in your leg that passes just below your knee and along the outside of your leg, explains Richard Graves, a medical expert. This pressure can cause numbness and temporary paralysis (麻痹) of some of the muscles in your foot and leg, preventing you from being able to raise your ankle—what we know as that “pins and needles” sensation. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.
So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.
