Holders of contact Many consider a good regular contact, and not medical devices. Because of health risks associated with improper care of contact lenses, it is imperative that consumers are aware of the importance of using them correctly. Such a mistake people make is too long contacts and contacts become worn.
Many contact lens wearers have been wearing contacts on worn. Studies on long-term side effects of wearing contact lenses, such as Zuguo Liu et al. , 2000, concluded that “long-term contact lens wear appears to decrease the thickness of the cornea and any increase in the curvature of the cornea and surface irregularities.” Excessive wear over contact lenses worn can affect on the eyelid, the conjunctiva, the various layers of the cornea, and even the tear film that covers the outer surface of the eye. (John Stamler, “Contact Lens Complications.” EMedicine. Com.)
long-term wear of rigid contact lenses is also linked to a decrease in keratocyte density and corneal increase the number of epithelial Langerhans cells. (Zhivov A, Stave J, Vollmar B, R Guthoff, January 2007 “in vivo confocal microscopy of Langerhans cell density and distribution in the corneal epithelium in healthy volunteers and contact lens wearers.) In Furthermore, over worn glasses can irritate the eye due to excessive dryness due to problems with tear production. The most likely risk of contact lens wear on corneal ulceration, or infection . Corneal ulcers occur more frequently in people who wear soft contact lenses because these lenses are comfortable to wear for long periods of time, thus increasing the potential to bring before the time when they should be worn. For States United, there is an estimated 12,000 corneal ulcers per year with people who wear contact lenses.
Another condition that can occur when wearing contact lenses more likely is the development of the sensitivity of the eyes and eyelids. Symptoms include: increased mucus, and redness of the conjunctiva. Abrasions of the cornea may occur due to wear over glasses worn. Symptoms of corneal abrasions are pain moderate and tear, stabbing pain, extreme sensitivity to light, and cloudy and blurred vision.
Extended use results of wearing improper contact in the lack of oxygen to the eye that can produce conditions such as:
atypical blood vessels increasing the clear part of the cornea called neovascularization.
Thinning of the cornea.
Irregularities in the size of endothelial cells known as Polymegethism.
The irregularities in the shape of endothelial cells called polymorphism.
We must stop wearing their contact lenses if their eyes become red or infected, if vision is blurred, or if the lenses become uncomfortable or too painful to bear. If symptoms do not disappear in a couple of hours, they should consult their eye doctor.
the contact lens wearers should take care when wearing their lenses. Your eyes are precious and the last thing you want to do is develop an eye disease or perhaps even lose sight. Never wear contact lenses longer than directed.

Contact lenses were invented by a German ophthalmologist, AE Fick, the earliest in 1887 and received the contact name then. However, they were not widely used until 1930, because the contact lenses in the early days were made of glass that breaks easily and thus dangerous for the eyes. And it was not until 1947 with the invention of keratoscopy, they started to become popular.

Comparing with traditional eyeglasses, contact lenses do have several modern advantages. The images we get through them tend to be more realistic, especially for people with high myopia. They have no frame so do not press the nose and without the frame you can also get a wider field of vision. And for girls beauty-hunt, contact lenses are absolutely more attractive to them than traditional glasses.

However, contact lenses have their drawbacks and are not suitable for everyone. Contact lenses almost stick to your corneas are in fact foreign objects in your eyes. So for some, wearing them can be very uncomfortable. As contact lenses have direct contact with eyes, they must be kept clean. So there’s always plenty of maintenance work tedious. People who can not maintain good personal hygiene are not ideal for users themselves. Adolescents whose eyes are not fully developed should not wear contact lenses for the side effects can damage their immature eyes. In addition, older people should avoid using contact lenses too. In fact, if you’re already in your 40s, you should begin to reduce the time to use contact lenses. A pair of aging eyes simply can not afford the comfort and beauty formed by contact lenses.

Environment also limits the use of contact lenses. If work or live in a place full of dust and smoke, it is advisable not to wear them. And if you’re in a closed environment with acid or alkaline volatile substance, you’d better not wear contact lenses, either.

So you can see, even if the lenses have many advantages, not everyone can wear. And even for those who meet the standard, they can not wear them in all places all the time. When using, be careful. After all, you do not want your eyes to go through any permanent damage, is not it?

Like most of us know, contact lenses are the best alternative to glasses. They are small, plastic shaped discs that are made to correct vision problems like myopia, astigmatism, farsightedness, and other problems. Contact lenses are also used by those who have undergone cataract surgery because they can help to heal the eyes a little faster. Contacts are used in the eye, where they float above a sea of tears that rest in front of the cornea. You should always consult a doctor to be fitted, as the correct installation and design is very important for safety, comfort and clear vision. If you do not get fitted for your contacts, you may very well have a pair of contacts that could damage your eyes. There are several types of contact lenses available in two main types – hard contact lenses and soft contact lenses. Contact lenses include rigid gas permeable lenses and conventional drive. Soft contact lenses include daily use, extended wear, and wear disposable. These are all excellent contacts, but you should check with your optician to see what he recommends. If you are just starting to wear hard contact lenses or have thought of them in the past, you will need a 2 – 4 weeks period of rest, where you can gradually wear the contacts longer and longer each day. Soft lenses, on the other hand, will have less time to get used to, like most people who wear them can break them in a few days. Contact lenses, as we all know, have many different uses. They are mainly used to correct vision, but they can also be used for those who have just had cataracts, especially if the natural lens around was removed. Contacts can also be used in the treatment of various eye diseases, and scars on the cornea that were caused by infections or injury. Contact lenses are an excellent choice for those with active lifestyles, such as athletes. They do not fall as glasses when you run, and they hang on your face or fog up. They also offer a field of vision as well, which is great for the sport. The focus and emphasis is the same as glass, which means that you get the same vision contacts you would with a pair of glasses. Many people who have vision problems consider Lasik surgery to solve their vision problems so they will not have to wear glasses or contacts. On the other hand, there are several risks and problems associated with this procedure, besides the fact that it is very expensive. Contact lenses are not expensive, and they are a safe alternative to vision correction. Keep in mind that the lenses are not available without prescription. Although you can get certain contacts without a prescription, they will not correct your vision. For the contacts correct your vision, you need to visit an eye specialist and get fitted for them. Your doctor will tell you the health of your eyes, and the contacts you need to correct your vision. For many years contact lenses have been an ideal way to correct your vision. They are more popular than glasses, and they do not limit what you can and can not do. Contacts fit snugly in the eyes and they will not make you feel for him. You can wear them with any type of clothes you want – because it is very difficult to tell if someone is or not.

Also known as oxygen permeable contacts, gas permeable lenses are much easier to take care of then other types of contacts – including soft contact lenses. GP (gas permeable) contacts are made of a combination of fluorine and silicone, which means they will not attract nearly as much protein as other types of contacts. If you had a problem with protein on the lenses in the past, GP contacts will almost eliminate this problem. Keep in mind you’ll still need to clean your lenses GP to keep them free of proteins, debris and keep them comfortable when you wear them. They clean much easier and faster than soft lenses, and they will outlast you. For many users of contact lenses, gas permeable lenses are the best way to go. If you wear contact GP or seek to wear them, you’ll need to keep re-wetting solution or saline drops with you if they start to dry. Each time your eyes feel dry, you can use the drops to moisten your eyes back up and keep your contacts comfortable. Re-wetting drops are normal use, even with soft lenses. Dryness in the eyes is very common with contacts, which explains why you should always have a rewetting drops with you. After wearing GP lenses during the day, you should always clean, rinse and dry after you retire for the night. When you clean them, you should always use the solution instead of water. If you soak them in water may damage the equipment, which could in turn damage your eyes. Depending on the type of contacts and the brand you have, you should choose the solution accordingly. The solution you use does not burn eyes or make you feel any kind of discomfort. When you go to your optician to have your eyes fitted for contacts, please ask the gas permeable contacts. If your ophthalmologist thinks they are right for you, it should recommend. Normally, they are for the elderly, or those who have had eye problems in the past. They are close contacts – and perfect for everyday use. If you have been looking for contact lenses that will not disappoint, GP lenses are just what you need. They can be purchased locally or online, normally at the same price of soft lenses. They last longer than soft lenses, which means you will not need to buy them as often. If you take care of them, they should last you a long time. Once you have tried gas permeable lenses and see how they are – you never look at soft contact lenses in the same way.

It is interesting that a technology called orthokeratology applied to your lenses can reshape the cornea into the night and provide a clearer picture, even without contact during the day. Although the magical effect lasts about one day, it is ideal for many people. Ortho-K was performed to reshape the cornea decades ago, but it has received full approval from the FDA that several years ago. The development of contact lenses Ortho-K has undergone a rigorous process. So far, some new manufacturing methods such as, geometry Äúreverse, AU and models such as lentils Äúreturn zero, the AU has a success rate of contact lenses Ortho-K. By deformation of the cornea, contact lenses Ortho-K can redirect light rays, making them focus properly on the retina. In this sense, the myopia is corrected. Eyeglasses, contact lenses and LASIK traditional perform the same way. Currently, Paragon Vision Sciences provides Corneal Refractive Therapy (CRT) and Bausch & Lomb offers a vision of a modeling (VST) that the certification for the practice of Ortho-K. Ortho-K lenses Others have no FDA approval for the port during the night. CRT is approved to treat up to six diopters of myopia and up to -1. 75 of the astigmatism, while VST has been approved to correct up to five diopters of myopia and up to -1. 5 of astigmatism. Ortho-K lenses adjust to all generations with healthy eyes. But they are more attractive to people like sports or work in dusty and dirty. Ortho-K lenses also work as a perfect substitute for LASIK so they are preferred by teenagers who can not accept surgery. According to research on patients who use Ortho-K lenses, most of them are getting a good view above 20/32. Before prescribing contact lenses Ortho-K, your doctor will measure your corneal curvatures using a corneal topographer, which is painless and takes a minute. The exact requirement can be reached after a trial. Contact lenses Ortho-K can reshape two to three diopters of myopia in two weeks, accompanied by side effects such as glare and halos. You should wear these lenses to maintain the prescription reaches more sleep or during part of the day. Ortho-K lenses are still comfortable during sleep because your eyes rarely blinking, so that the interaction between the eyelid and the edge of lens is reduced.

As we all know, contact lenses are becoming increasingly popular among people. So why are people more and more people choose to wear contact lenses instead of glasses frame? Without doubt, contact lenses have many advantages over eyeglasses frame. Now, let me tell you some major points in brief.

1. Contact lenses can keep the natural features of the wearer’s face. This is very important for those people who pay much attention to their appearance, especially women.

2. Contact lenses do not give the feeling of oppression at the bridge of the nose and ears. It is a clear advantage over glasses frame, because the lenses are not crowded and executives have no leverage. It is convenient for people to wear and they do not need to worry that the problem of the failure of the frame.

3. The contact lenses are suitable for people who take certain special occupations, like the soldier, actor, athlete and so on, because there is no gate frames and unlikely to opportunity to disrupt the glasses frame. That is to say, contact lenses provide comfort great for sports figures.

4. Contact lenses are suitable for people with degrees of myopia or hyperopia eyes have a big difference. For example, if the adjuster extends 2 to 2. 5D, the glasses with frames are not suitable, because the image seen by both eyes differ too. Because it is difficult for the brain to combine the two ghosts in one. However, contact lenses can reduce the difference of the image formation in both eyes. The rigid contact lenses can correct vision even people who are sick of the abnormal corneal astigmatism.

5. Contact lenses have effects of cosmetology, as colored contact lenses can cover floccosoids on the cornea.

Of course there are some other advantages of contact lenses. And I think if people can make good use of them, they will give people a comfort in return.

Contact lenses were developed through the ages since its first concept has emerged with Leonardo Da Vinci in 1508. Contact lenses modern age commercial production came on the market in 1949. They were made of Plexiglas. A kind of plastic material that is transparent in nature. These objectives may be over a longer period such as 16 hours. These lenses used to be mounted on the cornea rather than across the ocular surface. Here, the ocular surface comprises the white in the eyes. The cornea is the black portion on which the lenses are located. But there was a serious draw back for both this fact plexiglass lenses. The plexiglass will allow oxygen to enter the conjunctiva and cornea. It could lead to a large number of negative symptoms for the eyes. These objectives have been well Plexiglas really sustainable, but faced with this decline. Eyes are the most sensitive organ in the human body could not cope with any kind of potential damage. Needless to say with the development of artificial lenses and billions of dollars of contact lenses have also been practically involved indirectly. It is easy to understand that many people around the world have the problem of vision. Thus, once the right equipment is available on the market for making lenses that would be durable, lightweight and clear, then he would demand worldwide. Thus, in many parts of the world technologists continued to work on this project. In the late 1970s throughout the 1980s and 1990s popular contact lenses entered the market. The problem may be of several types. The most common of them often found in cases of elderly and older people regardless of their sex is difficulty seeing objects close range.
