Also named as GP lenses, rigid gas permeable lenses, RGP lenses and oxygen permeable lenses, gas permeable contact lenses are a type of rigid lenses which are made of oxygen-transmitting durable plastic. Most people may have heard and worn the old-fashioned hard contact lenses which are made of PMMA. Totally different from the outdated hard contact lenses, GP lenses are more advanced as they offer us more eye health and they are easier to clean and handle. Another distinctive point of GP lenses is their remarkable durability.

Why are GP lenses so out of the ordinary?

1. Special oxygen permeability

The craftsmanship of GP lenses has exploited gas permeable contacts that were first introduced in the 1970s. Acknowledged as better, those soft lenses, rigid GP lenses, incorporated by a type of more flexible material called silicone, are well accepted to be comfortable and cozy to wear. Moreover, the most distinctive feature of GP lenses is being oxygen permeable. Oxygen is free to pass through GP lenses and in this way our eyes are better protected and in a more comfortable position. Oxygen is not merely critical to our life force but also functions as our eye protector and savior simply via GP lenses.

2. Stronger practicability

When we say GP lenses are of stronger practicability, we actually mean that they can be custom made for every one and they are particularly durable and resistant. Whatever your cornea shape and prescription are, GP lenses can be uniquely made right for your unique curvature, size and corrective power. With the increasing improvement of contact glasses manufacturing, GP lenses are boasted to be thinner, larger and smoother in the edge. All these progressions made in GP lenses ensure wearers good comfort and crystal clear vision.

Who are especially in need of GP lenses?

GP lenses are in general fit for every individual, but at the same time they are more than ever suitable to those who feel uneasy with the obsolete soft lenses.

1. People who are in pursuit of high-quality vision can resort to GP lenses.

2. GP lenses can be all the more contributive to correcting astigmatism. People suffering astigmatism can replace their soft contacts with GP lenses which are to provide them with more desired vision acuity.

3. GP lenses can be of bifocal and multifocal design which does good to people with  presbyopia.

4. GP lenses do a big favor to people whose cornea is cone-shaped which causes visual distortion by the use of soft lenses.

5.  People who have just recovered from eye laser surgery can turn to GP lenses for a more safe and comfortable wearing.

Some extra things you should know about GP lenses.

It is a fact that now GP lenses are not as widespread as soft lenses. The main reason is that it will take a period of time for people to adapt to GP lenses while soft lenses are more adaptive and instantly comfortable. Put aside for a few days, GP lenses would not be so easy to wear as before. You will need another adaption period. Moreover, GP lenses are to move on the eye as wearers blink, so it is necessary to be careful of the risk of dust and debris sneaking under the lenses. In short, wearers should be careful about GP lenses because they are expected to last for at least one year.

Nowadays, a lot of people spend a significant amount of time wearing contact lenses due to the convenience of contact lenses. When it comes to the contact lens prescription, some people still use their expired contact lenses prescription while purchasing new contact lenses. It is reported that the contact lens prescriptions are valid for one year according to a law passed in 2004. This is because you should have an annual eye exam to make sure your eyes are remaining healthy and your refractive error is unchanged. Therefore, it is crucial to make an appointment with your optometrist after your contact lenses prescription has expired.

In fact, contact lenses are a foreign body in our eyes. A contact lens lies in the top of the cornea and is close to the inner tissue of the eyes. If contact lenses are not prescribed properly, you can’t see clearly. What’s worse, contact lenses with improper prescription may lead to many eye problems such as discomfort, inflammation, swelling and abrasion, etc.

Experts declare that improper contact lenses will give rise to lactic acid build-up within the cornea and then cause swelling. The cells in the cornea will spread apart as long as swelling occurs. If so, it is easier for bacteria and viruses to have access to other spaces in the cornea, which may result in infection. Beside, your eyes may become lack of f oxygen when you wear improper contacts. Due to the oxygen deprivation, new blood steaks are likely to grow into the cornea.

Generally speaking, you must pay much attention to make sure whether your prescription is accurate or not. If your contact lens prescription expires, you shouldn’t buy new lenses until you get an updated prescription. You’d better have a checkup by your eye care professional (ECP) to get the accurate contact lens prescription.

Many contact lenses wearers misinterpreted the” free attendance eye washes “ will provide them all-sides assistances with their contact lenses, it is rather a misconceptions actually, several days ago, “Professional Experts Conference with Contact lenses Attendance” emphasize the “ free attendance eye washes” just keep a instant attendance to wearers and induce the possibility of eye injection.

It is investigated, the improper attendance with contact lenses will increased the rate of

Cornea injections to 11 degrees, some consumers can not accordance with the regular process of attendances as they are always busy with their life and works, 49% of consumers response that they haven’t normal contact lenses attendances; 80% consumers admit that they only read the attendances in the purchasing time. However, one third of sufferers diseases caused from the improper attendance and cleaning habits.

It is reported that the regular sufferers always can not in accordance with the right process to attend the contact lenses, attending the eye wash, uncleanness with their contact cases, over-time wearing contact lenses and so forth. Besides, some other improper attendances which include: don’t wash their hands before attending contact lenses, clean lenses with water, washes it with roughly, wash lenses in a long period after a long period of time, use the worn and uncleanness cases, etc.

The analysis also implied that nearly 70% consumers ignore of their one day clean process. Only 29% consumers change their cases every half month, the most serious cases: more than 26% consumers change their contact cases over 1 year or don’t change it at all.

At present, every ten thousands contact wearers refer to five to ten of them suffered from eye diseases result from the microbe inflammation or injections. Rubbing and washing is the solution to clean 80% sediment. When the contact lenses deposited more than seven days, we should sterilize the lenses before the next wearing.

Of later, I decide to change my eyeglasses, the last one was broken during the sport games, it is not worn actually and just within several months, I will keep it if it is still well in shape. With this experience, I feel that eyeglasses are not convenient for doing sports, especially for playing ball games as it involves in some adventure actions. We always worry about some damages to my glasses. So theses time, I decide to consider another eyewear: contact lenses. Before I take action, three of my friends, Ally, Lisa and Ella have different opinions on these picking.

Ally think Glasses are better choices for eyes since they don’t sit on eyeballs and can trap dirt and toxic fumes. It is also possible to get infections from wearing contact lenses while that is virtually unheard of with glasses. She has not been to successful in being able to wear contact lenses for years due to a number of problems including living in a dry climate, having dry eyes and having to wear a strong prescription. I was told at the place where I got my most recent pair of glasses that contact lenses for strong prescriptions are thicker and don’t allow your corneas to “breathe” as much as thinner lenses.

Lisa says eyeglasses don’t require you to put something directly in your eye so there is less of a chance of something going wrong. Anytime you put something in your eye there’s a chance you could screw up and give yourself an eye infection. It really comes down to how careful you are. If you are a careful person it’s not a big deal – if you drive fast, spill your drinks and forget to water your plants; you might cause yourself a problem.

While, Ella takes different viewpoints, she agrees with contact lenses options by and large. “You should make clear the time of wearing, eyes need oxygen and if you wear contacts for an extended period of time, then your eyes will go red, if you do this enough they will stay and your eyes will be permanently red. Not really bad-but noticeable. So if you plan on wearing contacts for long periods of time- they might be the best options for you.

With their wonderful analysis, I think I should consider two of them because both of them own their advantages.

Do you know what toric contact lenses are? I didn’t know them either until one day I found I had a blurry vision. I went to the doctor who told that I had astigmatism. With explanation from the doctor, I came to be aware that astigmatism is one where rays that propagate in two perpendicular planes have different foci, and corrective lenses are needed to get it corrected. However, if you do not want to wear eyeglasses, which constitutes a burden to the wearers, you could choose a special contact lenses designed  for astigmatism correction, called Toric contact lenses.

Compared with regular soft contacts, toric contact lenses have two powers in them, created with curvatures at different angles, one for astigmatism while the other for either myopia or hyperopia. What’s more, they are weighted which enables them to sit on eyes properly and correctly in place. Another feature is that there is a line on the lens near the identifying numbers to indicate the bottom of th lens, therefore, at the very few seconds after you put them on, you would experience discomfort or blurry vision. However, if your blink for sometime, everything would turn out to be ok.

Facing so many different brands, one who firstly comes to contact toric contact lenses would feel puzzled which one to choose. The suggestion is to try one by one to find the most suitable one for you. As a matter of fact, your eye doctor will advise certain brands for you according to you personal eye condition. And those who need a high prescription should choose lighter weight, for heavier ones would restrict oxygen flow to the eye, resulting in dry eye symptoms.

Besides wearing Toric contact lenses, astigmatism patients also have an option of undergoing a surgery. But the problem is that an eye surgery always costs a lot, and not every one is able to afford. What’s more, patients have to take a risk to have a surgery and this may not what one wants.

In my opinion, the best way to keep oneself away from toric contact lenses and eye surgeries is to prevent the emergence of any eye problems. If you, up to now, have a good eyesight and do not have any eye disease, you are suggested to get regular eye examinations every year. And you have to keep doing it, because eyes are constantly changing through out life.

It is true that wearing lenses while swimming can ensure swimmers see much clearly of objects in the water.

Another is there are still some bacteria or virus that may be left in eyes if lenses are used. What’s more, some lenses can absorb water and the result is eyes and lenses may stick together. Therefore, it is not a good idea to wear contact lenses while swimming. Or if lenses are really needed, some special goggles should also be employed.

Another phenomenon is many people tend to have contact lenses in their eyes while bathing or showering. It seems that this will do little harm, for little water might come into eyes. However, there are really many users forget to remove lenses and have their eyes infected after bathing or showering. This reason is similar to that of in swimming pool.

Moreover, people tend to wear contact lenses before washing their face. It is true that inserting lenses first can really bring more convenience. However, washing face with lenses may also lead to certain problems. This is because some people often have their eyes saturated with water and the result is contacts are also saturated and discomfort comes, or eye infection can not be avoided in some cases.

In a word, wearing contact lenses while doing water-based activities will not lead to horrible results, but some troubles or discomfort can not always be avoided. Thus, it is a good idea to remove lenses before swimming, showering, bathing, or washing, etc.

They can be used for vision correction, cosmetic purposes, etc. Therefore, many buyers are confused by wide selection of items in the market. In fact, contact lenses can be mainly categorized into two major groups, namely, soft lenses and rigid gas permeable lenses. As their names indicate, soft series are made from water-containing materials and can bring users a lot of comfort, whereas rigid series can be used for much longer time.

Of course, both soft lenses and hard lenses can also be subcategorized into further groups. For example, all of them can be divided into other kinds from the perspective of wearing time. In the market are now daily, weekly or monthly lenses. Or there are also lenses that can be slept in.
