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 Totally different from the outdated hard contact lenses, GP lenses are more advanced as they offer us more eye health and they are easier to clean and handle.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.

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.

Moreover, people tend to wear contact lenses before washing their face. It is true that inserting lenses first can really bring more convenience.

Moreover, the care and maintenance of contact lenses should never be neglected. In particular, new users should be more careful.
