People who are near-sighted can only see things that are very close to their eyes. Everything else seems blurry. Many people who do a lot of work, such as writing, reading and sewing become near-sighted. People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distances as people with two eyes.

Hair loss can be due to a variety of factors, including a genetic tendency (which is not genetically linked to just one parent—both parents contribute to the tendency to lose hair).
Women who are experiencing hair problems seem to have more limited choices than men. There are some female hair loss treatments that are available such as the Tricomin System which is a topical treatment that is nutrition based. Shen Min for Women is another natural treatment that contains herbs (药草) that are said to stimulate(刺激) hair growth and even restore hair that is graying to its natural color.
The majority of the popular, prove hair loss treatments are only intended for men and are not suitable for women. True, a woman’s hair issue is different from a man’s. The biological makeup is different and the needs are different. Women have different needs and their bodies react in different ways to environmental changes, physical illness and even the treatments that are available. There are many natural treatments such as vitamin and mineral supplements that are said to stimulate hair growth, but, for the most part, these claims are currently unproven.
One of the first and most important factors to effectively treating is to get a diagnosis from a doctor. Talk to your doctor about any symptoms(症状) that you may be experiencing in addition to the thinning hair. Stress, weight loss or gain, illness and depression, all of these can be contributing factors.
