In the surface of our eyes, there is a thin tear velum which has the function of lubrication. When you blink, the thin tear velum will refurbish and keep our eyes wetness.
For some people, they don’t know many things about their eyes, even though they are myopic; of course, they don’t know that they ought to keep their eyes in the condition of wetness. Therefore, when their eye hurt, they don’t know why. In this rapid development time, there are many things for us to use our eyes, especially when we use a computer, watch a TV program or play PSP; we have to put all our attention on it. Now and then you are so focused in it that we don’t know what has happened around us. However, this is quite bad for our eyes. That’s because ten seconds later after our eyes focus on one thing, there will be a dry dot appearing on our tear velum. As a result, the surface of our eyeballs will become drier and drier. It’s likely that we won’t have much feeling at first; while not long later we are able to feel that our eyes are quite dry.
The best way for us to use our eyes to let them have a rest after a certain time we use them until they become wet again. Normally, our eyes will blink about 15 times every minute. However, when we focus on reading or using computers, it’s likely that we only will blink no more than 10 times every minute. As a result, our tear velum become smaller and smaller. Since it become small, then the function of keeping our eyes wet will become weak or even lose. So our eyeballs become quite dry; and then when we close or open our eyes, our cornea and eyelid are easy to brush burn. It may results the dryness of our eyes, the tiredness of our eyes, inflammation and ache. At last, we are going to suffer from xeroma, one of eye diseases. Considering that we are already a nearsighted sufferer, we have to let our eyes get enough rest when we are using computer or watching TV programs. Otherwise, our strength will be worse and worse.
Therefore, we can see that it’s important to protect our eyes. After all, each of us only has one pair of eyes. We ought to pay much attention to the health protection of our eyes. Although for some of us it’s impossible not to use computers in our daily life due to this or that reason; it’s possible that we let our eyes have enough rest after a certain time we use them. Thereby, our eyes won’t become worse and worse. What’s more, when our eyes are in a good condition, the efficiency for us to do our work is quite high. Keeping our eyes wet, we are able to have an excellent day every day.

Normally, people may have presbyopia at the age of 50. But nowadays, more and more young people get presbyopia. The main reason is the excess use of eyes. Most young people have to work for a long time and use their eyes more often.
For example, at work they can’t avoid looking at computer screens and they will watch TV or read newspapers after work. These all lead the exhaustion of eyes and the early emerge of presbyopia.
One of the old myths about eyes is that they won’t get presbyopia if they are already shortsighted. Actually, presbyopia is unavoidable for every body. Shortsighted people will get presbyopia once they get the certain age. The symptom is that it feels uncomfortable to see things close with the original glasses. And this suggests a new pair of glasses.
Some people will go and get presbyopic glasses at random after they find out that they have presbyopia. Their only requirement of the glasses is that they can see clearly with it. This is absolutely wrong. Presbyopic glasses also have degrees. Some one even has to wear one pair of presbyopic glasses with different degrees for each eye. It will do big harm to the eyes to wear the presbyopic glasses with incorrect degree for a long time. The correct way is to have a careful examination in formal hospital and to wear the presbyopic glasses which fit the eyes well.

The first step is to make sure the eyes get enough rest. Adults should sleep for 6 hours per day. The best time for eyes to rest is from 11:00 pm to 3:00 am. It means only by falling asleep before 11:00 pm can one’s eyes have the best rest.
The second step is to relax the eyes regularly during the daytime, especially when one’s work involving long time staring at things close. The time between two relaxations should not be longer than 1 hour and each time the eyes should have rest for at least 10 minutes. People can just let the sight off the screen or books and to look into the distance, or do some simple eyes exercise and move around a little bit.

With the improvement of life, and the necessity of beautifying and convenience, contact lens has already become a kind of essential product in daily life. However, facing more and more negative news about contact lens, are you at a loss when dying to choose a proper one from various kinds of lens? Sometimes, if we take notice of scientific ways of selecting and using contact lens, those confusing problems can be definitely avoided. So contact-lens-attached guys, let’s now take a look at the problems below altogether! Have you ever paid attention to these problems?
There are free of blood vessels in the cornea, so the cornea needs to drink in fresh oxygen in the air so as to maintain physiological function of the cells. Therefore, in judging whether a pair of contact lens is good or not depends on whether the lens have a good performance of passing through oxygen, which is also a technological problem that puzzles the manufacturers of contact lens for all these years.
The common contact lens in the market today are made of water gelatin, in which water works as the media of passing oxygen to the cornea. However, when you wear contact lens for a long time, the water contained in your contact lens will evaporate little by little. At that moment, your eyes would get dry and turn red.
At present, it is popular in European countries and United States to apply a kind of new material, the so-called hydrated silica gelatin, in making contact lens. The hydrated silica gelatin, which have lain in the mainstream of material used for making contact lens, are characterized by unique double channels that make the amount of oxygen passing through the lens become five or six times larger than that by the ordinary water gelatin. As a result, a qualitative change takes place in the oxygen-passed capability of the lens.
The good performance of passing oxygen through the cornea brought by hydrated silica gelatin deals well with the problems in eyes concerning getting dry and red and keeps the cornea more healthy.
The care solution is mainly used to clean and disinfect contact lens, wipe off albumen on contact lens, etc. Undoubtedly, it is essential for contact lens wearers.
In order to meet needs of different users, the care solutions are assorted into various kinds of types. You can choose basic care solution if you just want to clean and disinfect the lens on every day. Or, if you want to keep your contact lens damp, then you can choose the moisturizing solution that has the function of hydratation.
Another kind of care solution is called intensive care solution. Daily care can be matched with intensive care. The basic and moisturizing solution can be used for daily cleaning, while the intensive care solution can be applied in clearing up the lens to the core. This match is just like the combination of ordinary cleansing milk and facial cleansing mask of special effect. One is for daily use, and the other is for weekly clearing.
