It is reported that wearing contact lenses for a very long time will damage eye conjunctiva. Many little particles will appear inside conjunctiva. What’s worse, some unqualified contact lenses will decrease endothelial cells of conjunctiva that can’t regenerate. Besides, wearing contact lenses will make cornea lack of oxygen. In the normal situation cornea directly absorbs oxygen to breathe, while contact lenses prevent cornea from breathing oxygen. As a result, blood vessel will dilate or new blood vessel occurs and leads to blood steak.

Therefore, ophthalmologists suggest that people should prepare a pair of glasses as an alternative for contact lenses. You can wear contact lenses when you go outside. When you get off work, or stay at home, you’d better wear glasses. In addition, you must take off and clean contact lenses everyday. Don’t wear them overnight or your eyes are likely to swell or ache. In term of maintaining contact lenses, you should keep the following points in mind. First, don’t soak contact lenses with solutions for a long time. If so, solutions are likely to lose function of disinfecting. You should store contact lenses with new solutions after two days. Second, don’t blend solutions with others that are produced by different manufactures. Blending different solutions may lead to chemical reaction and then damage lenses.

So it is important to take contact lenses seriously because it can help you and cause damage to your eyes as well. You’d better pay attention to use contact lenses and maintain them.

Wearing colored contact lenses may be the simplest trick to have a quick change to the eye’s appearance. A completely different look in the eye can be easily achieved because the eyes are actually one of the most predominant features. Any change to the eyes will be quickly and even instantly noticed by others. Nowadays, there are a lot of people who have been indulged in this effective yet simple option of changing eye look. It is nearly possible to get any color as a wearer wants his or her eyes to express. In detail, personal requirements will also be met in term of lens type.

There are mainly opaque colored contact lenses and enhancement colored contact lenses. For people who need still natural look for daily ware, enhancement colored lenses that only slightly enhance the natural eye color are appropriate. In different, for those trying to complimenting a costume or dress up as an exotic creature from a favorite film, opaque colored lenses are then a right choice. All in all, the decision depends on personal purposes. Within each type, there are a vast selection of colors and models. Basics include blue, green and hazel and the exotic like vampire red lenses or dark lenses with glow.

Like purchasing many other products, customers can get great deals while buying colored contact lenses if they resort to the Internet. Online retailers of contact lenses always offer a wider selection of products than those local stores. For instance, a typical online shop would provide a section of prescription colored contact lenses, which flatter some people’s double needs. Due to the wide spread of colored lenses, their average price has been considerably brought down in recent years. Good news is that colored contact lenses do not require additional caring compared with regular prescription lenses. But one difference is that colored lenses can be worn only for part of the day.

For first time contact lens wearers, it is highly possible that they are scare to put the contact lens into their eyes. As a matter of fact, wearing contact lens is not as scary as they imagine. Perhaps the idea that contact lens can get slide behind our eyes and get lost scare most people. Is it true that contact lens can get lost in our eyes?
 
First, let us discuss if the contact lens can slide into the space behind our eyeball. Outside of our eyelids, there is a strong transparent membrane called conjunctiva, which fold back to cover the front part of our eyeball. So in this way, contact lens is literally impossible to get through it to side behind our eyes. Therefore, from now on, we should not be afraid the contact lens can get into the back space of our eyes any more.
 
But it is a true fact that contact lens can move around and dislocate in our eyes. The lens should be placed in the center position, but due to some reasons, they are positioned under an eyelid, which will cause people some discomforts, especially when they wear hard lens. If we have to face this case, do not worry. The thing we need to do is to have the lens back into their original position.
 
The reasons for our lens out of position are as following: First, this maybe caused by our careless rubbing our eyes. If we do not pay attention to rub our eyes, it is highly possible to move the lens under our eyelid or even make it out of our eyes. So next time, when we rub our eyes, we can rub around the contact lens in order to make it in their position. Besides, the weather and our activity can also contribute to dislodge of our contact lens. For example, if we are outdoors on a windy day, it is likely for the lens to move around. Under windy day, our eyes will have more water and tears, and the excessive teas can even make the lens “float” in our eyes, so when we blink, the lens is more likely to move to other place, or even come out of our eyes.
 
You may wonder to know how to re-locate the lens. First, we should know where the contact lens is now. If we don’t know the exact position of the lens, we can use our fingertip to feel outside of our lids. Then look at the direction where the lens is. If our contact lens is down, just look down. In common cases, the lens can get back to center position. But for hard contact lens which is not easy to move back, we may need to use our fingertip to push the lens back to their original position gently. When we do this, make sure not to press the lens into our eyes, or else, it may cause painful scratches in our eyes.

Contacts lenses are some of the most widely used optical products among wearers of different groups. Some of them are just used for decoration and some others for healing, but most of them are mainly used for vision correction. They are now some of the most beloved options for glasses wearers, who may think eye glasses are too inconvenient to use. Comparatively, contact lenses are convenient and easy to use and much easier to maintain.

Of course, another reason why many people tend to wear lenses other than glasses is personal images. Glasses may make some wearers pedant or ugly to look at. But contact lenses are completely different. Especially, lenses are also nice options for people with particular needs, like doing sports activities.

Similarly, contact lenses should also be prescribed like glasses. And the eye doctors should also be highly qualified, this is because contact lenses are much special and their prescriptions must be more strictly made. This is also why contact lenses must be approved by FDA. Therefore, an accurate eye exam is needed in the prescription.

However, people with sensitive eyes may have some problems in wearing these lenses. If so, they should pay more attention the type of lenses. Lenses can on the whole be fallen into disposable and extend eyewear. And people should be very careful in maintaining them. Especially, they should know how to clean and disinfect lenses. Only in so doing can wearer’s eyes not be infected.

Anyway, contact lenses are ideal options for people who want to be stylish, but do not want to wear glasses. Keep in mind that lenses maintenance is very important.
