RGP Contact Lenses – Custom Made For Extended Wear

January 10, 2012

RGP contact lenses are designed for extended wear. put an RGP lens in and you can leave it there – overnight, all week and even, is some cases, for a full month – without worrying about irritation or an increased risk of developing eye infections. They’re also custom made to fit your eye.

R.G.P. stands for Rigid Gas Permeable. RGP lenses are rigid because they are made to be reworn. They’re stiffer than the soft lenses people generally refer to when they talk about ‘contacts’, so they won’t tear easily and are excellent at correcting astigmatism, an optical defect caused by a cornea or lens that isn’t spherical. It most often leads to blurry vision – an irregularly shaped eye can’t bring a single point into sharp focus – but astigmatism also triggers headaches and, in some cases, chronic fatigue. RGP lenses are so good at correcting the condition precisely because they’re rigid. While you’re wearing them, your cornea and lens are pressed into the right shape and held there.

RGP lenses are gas permeable because your eyes need to breath. They’re narrower than ordinary contacts and made of materials that are highly oxygen permeable (RGP lenses are also called oxygen permeable lenses), so your eyes function normally while you’re wearing them. In the past, lenses intended for continuous wear increased the possibility of contracting an eye infection. Sometimes – after long periods of continuous use – they also led to acute irritation. The reason was simple: the organisms that irritate and cause infections thrive in warm, moist environments, exactly like the environment underneath a contact lens. to fight these organisms, your body would normally increase the oxygen supply to the affected area, in this case the cornea, but the lenses made this impossible. Peoples’ eyes were literally suffocating, and doctors eventually decided that no contact should be worn overnight – until RGP lenses came along.

Today, laser eye surgery (or LASIK, to those in the know) is often prescribed for astigmatism. and with good reason: LASIK is a low risk, permanent solution. It can give you 20/20 vision in the course of a short, painless procedure – but it isn’t for everyone. some people are not good candidates for LASIK: you might be younger than 18 or have a condition that makes LASIK impossible. Others just can’t swallow the idea of surgery, however uninvasive, on their eyes. The choice is personal, but worth making because, either way, you’ll once again have perfect vision from the moment you open your eyes in the morning, until the moment you close them at night.

Can An Eyeglass Prescription Be Converted For Contact Lenses?

December 4, 2011

In the first instance, it should be made clear that a prescription for contact lenses is not the same as a prescription for eyeglasses. so, one can say that it is not possible to do a direct eyeglass to contact lens conversion. however, the eyeglass prescription can be used in the construction of the contact lens prescription, by making allowances for the change in distance between the corrective material and the optic lens.

The prescription and fitting for contact lenses involves a good deal more than a similar prescription and fitting for spectacle lenses. For those new to wearing contact lenses, the fitting will be very new. This will again vary, depending on the type of lens being fitted.

The matter is further complicated depending on the type of lens being prescribed. Hard lens fit the eye differently to soft lenses, so allowances have to be made depending on the material being used for the contact lens itself.

Your contact lens practitioner will probably start by doing a refraction to determine the refractive error of your eyes, and then take further measurements, such as the tear film assessment and the corneal curvature to determine the best fitting contact lens and best material for your eyes. An exam and fitting for contact lenses can include your spectacle prescription.

One should also be aware of the increased maintenance cost of contact lenses. This includes more regular checks on your eyes, and more frequent replacement of the lenses. you should also include the cleaning and storage materials in the cost of lenses because they are a critical part of your eye health care.

In summary, whilst your eyeglass prescription can be used to help with the contact lens prescription, it cannot be assumed that the former can be used to create the latter.

Best Possible Exam Results – Ten Things to Do Before A Big Exam to Get Them

November 17, 2011

What can you do right before a big test – let’s say starting the
day before a big test — to get the best possible exam results?
Even if you are already a great test-taker you’re probably
looking for that extra edge to create the best possible scores
on your exams.

Here are ten things you can do to create better results on your
exams.

The Day before -

1. Review Key Points — Notice the word Review — the day before your test is less than ideal to be first learning something.
Hopefully you have already mastered the material, and it is just
a matter of giving that material an extra polish.
2. Eat Well-balanced Meals — Remember the phrase, you are what
you eat? be sure to keep your body and your brain in peak
condition by feeding it the nutrients it needs to perform at its
best.

3. Feed your Ruminator — whatever we spend time doing,
thinking, and seeing in the 45 minutes before falling asleep is
what our brains ruminate on throughout the night. So it’s to
your advantage to feed it — the things you want to remember for
the next day’s exam.

4. Envisioning your Success — just before you drift off to
sleep, create a picture of yourself successfully completing your
exam. It’s most effective if you do it every night, but even one
day before your exam could make a significant difference in
creating better exam results.

5. Get a Good Night’s Sleep — you need your 7-8 hours of quality
sleep to perform at your best.

6. Eat your Breakfast — Keep your body, mind and blood sugar in
balance.

7. Do Light Exercise — Light exercise will help you feel good
and energized, and help get more oxygen to your brain.

8. Do a Light Review — Glance through your exam preparation
materials one more time, and do any last minute checks you feel
you need.

9. Keep the Exam in Perspective – It’s just a test, not the end
of life on this planet. allow yourself to relax and let your
worries go.

10. Breathe — a lot of students tense up, and forget to breathe,
or take shallow breaths. be sure to breathe deeply from the
diaphragm. this will help your muscles feel better and will help
to clear your head and allow you to think better.

So the next time you are facing a big exam, follow these tips
and create great exam results

Contact Lens Cleaning Solutions – Everything You Need to Know

September 22, 2011

Trying to choose a contact lens cleaning solution can be a little intimidating. if you take a look at the dozens of different types and hundreds of brand names available, its pretty confusing at first. Knowing just what each type of fluid is for will help you make your choices. Your optometrist can also provide useful information on selecting the right cleaning solution for your particular contact lenses.

The first thing you need to know about selecting a cleaning liquid is to choose one that is formulated for the type of contact lens that you use. if you have soft lenses, be sure to buy only cleansers that are meant for soft contacts and vice versa for hard ones. by regularly cleaning your lenses, youll end up being able to use them longer and they will work better, without irritating your eyes.

Multi-Purpose Cleaners
These are the easiest types of cleaners to use. You only need one solution to do all the tasks, soften the lens, remove deposits, cleanse and disinfect. the only thing you have to do once the lenses have soaked is rinse them in saline solution before putting them into your eyes. Its very simple, but not always as effective as using multi-step procedures with a different solution for each process.

Multi-purpose cleaners can be used for most of the cleaning that you do, but if you want the occasional deep clean, then you might want to do a multi-step cleansing.

Saline
Saline solution is pretty much the same as your tears, so this liquid is ideal for soaking contact lenses in when they arent in your eyes. the liquid keeps them supple and hydrated and wont irritate your eyes later on. Saline is also useful for rinsing harsher chemicals off the lenses so you wont end up with stinging eyes later on. Contact lenses do tend to dry out when left out of saline, so be sure to always have some on hand.

Hydrogen Peroxide Cleaners
You are probably familiar with hydrogen peroxide from your medicine cabinet. It is also used in some types of contact lens cleaners to help eliminate grime and mineral deposits on the lenses. Hydrogen peroxide cleansers must be carefully stored and, while they do work very well for cleaning, the chemical can also cause intense discomfort in the eye, so be sure to rinse very well before using your contacts after cleaning them with a hydrogen based product.

Enzymatic Cleansers
With any extended use contact lenses, protein from your eyes will begin to build up on them. this can cause problems if left, particularly diminished vision and later, possible scratches and infections in the eye, so its important to get rid of these deposits. Enzymes in enzymatic cleaners work to destroy any protein deposits and leave the lenses nice and clean. this type of cleaner is usually in tablet form and is not needed on a daily basis. Once a week or so, drop a tablet into the liquid that the contacts are soaking in and leave overnight to get rid of everything. in the morning, the lenses will be ready to be used again after rinsing.

Since contact lenses are in contact with your eyes most of the time you are awake, its vital that they be maintained in a clean, sterile manner. Improperly cleaned lenses are the cause of many eye infections and these can range from a minor inconvenience to actually causing blindness. as you can see, its certainly worth maintaining a careful cleaning schedule and using the proper contact lens solutions for the job.

What is RGP Contact Lenses?

August 31, 2011

RGP contact lenses as they are normally called is a short form of rigid gas permeable lenses or also known as oxygen permeable lenses. They are not as common as soft contact lenses but they have been around for more than 20 years or so.

How are RGP Contact Lenses Different from Soft and Hard Lenses?

1) the old style of hard lenses are made of material called PMMA. This material makes hard lenses very uncomfortable to wear. Whereas RGP’s technology includes silicon and that makes them more flexible compared to PMMA.

2) RGP’s are also known as oxygen permeable since silicon is oxygen permeable and would let oxygen pass through the lenses. therefore they are more comfortable and consequently healthier for the eyes.

3) Compared to soft lenses, RGP’s are more durable since they are made of stiff materials.

4) They are also smaller in size compared to soft lenses.

What are the Benefits Of RGP Contact Lenses?

1) RGP’s are very durable. They are not easily breakable or tear off. that would make them easy to clean and handle. therefore they would last longer compared to soft lenses.

2) They also provide better vision even when you blink since they are made out of stiffer material so their shape is retained and not easily changed.

3) They last longer so over the long term they would less and a good investment for the money.

4) They provide better deposit resistance for your eyes compare to soft lenses. Proteins and lipids from the tears do not stick easily to RGP’s as they do with soft lenses.

What are the Disadvantages Of RGP Contact Lenses?

1) They are not as readily comfortable as soft lenses. your eyes will need some time to adapt to the RGP’s before they can become comfortable.

2) You need to wear them on a very regular basis. Since if you take them off after a while then your eyes need some time again to get used to them.

3) Since they last longer and can be reused for one year or more they require some care.

Who are the Candidates for RGP Lenses?

1) People with astigmatism, since soft contact lenses do not give the desired vision accuracy.

2) People who needs bifocals and multifocals lenses. Many people find that gas permeable bifocal works well with them.

3) People who have Keratoconus, that is the cornea is of cone shape and can distort vision badly.

4) People who are fussy about the quality of their eye sight, since RGP contact lenses could provide a crisper vision than soft contact lenses.

Where could I get an electronic contact lens cleaner?

August 13, 2011

online or in store is fine

thanks

I bought one of them several years ago. Save your money. I think they damage the lenses after a couple of uses and they get saline in the electronics and corrode in just a few months. I finally found the ideal combination for me was Clear Care (the peroxide based cleaning system) and Miraflow. I have sensitivity to pretty much all the multipurpose solutions and with Clear Care I finally have lenses that I can't feel in my eye for the first time.

Why do all Optometrists have bad breath?

August 12, 2011

I have been to many Optometrists and they all get so close to your face it is sometimes unbearable, they always have bad breath, i think they should all wear masks just like Dentists do, is it the coffee they drink? or what ? maybe they should see a Dental Hygienist because its not nice to go there and sit in that chair having to smell their breath.

lol i never had that problem

Funny all the dentist I go to wear glasses. since as long as I can remember.

They all want to make oral spectacles of themselves.

This is not related to Australia LOL!

Not a question for the Australia section… But I agree with you. take tic-tacs and offer them one!

Eye Tests For VDU and Computer Screen Users

August 4, 2011

We are all spending increasing longer hours in front of computer screens, whether at work or at home. according to unofficial estimates, as many as one in three of the UK workforce are unaware that they have vision defects, which need to be corrected to prevent further deterioration, especially if engaged in visually demanding VDU work.

Early warning symptoms for workers with an uncorrected vision defect could be reoccurring pain, headaches and blurred vision which may result from working at a VDU. On request, an employer must provide and pay for an eye and eyesight test carried out by an optometrist or doctor, with an entitlement to further tests at regular intervals.

DSE Regulations, which include specific requirements for testing, cover both eye examinations and sight tests.

The Regulations state that employers of both existing VDU users and new users: shall ensure that he (sic) is provided at his request with an appropriate eye and eyesight test, any such test to be carried out by a competent person.

Occurrences of vision screening tests only – not full sight tests – may be offered by employers as a means of identifying those who need a full sight test (although users will still be entitled to request a full sight test). it is often the case that lack of in-depth knowledge of the distinction between eye examinations, vision screening and full sight tests, may lead to many VDU workers being deprived of their rights, i.e. the purchase by employers of a piece of electronic equipment to do the job to ‘save them time and money’ does not fulfill the requirements of the regulations.

The Regulations clearly state that employers must offer employees testing by registered ophthalmic opticians (optometrists) or registered medical practitioners with suitable ophthalmic qualifications. the Regulations also specify that eye examinations and sight test reports should be made to both employer and employee by the optometrist, and should also state whether or not corrective appliances (i.e. glasses or contact lenses) are needed for VDU work.

If the eye and sight tests show that an employee needs glasses (corrective appliances) specifically to correct vision defects at the viewing distance of the VDU, then the employer must provide them.

Where special glasses for VDU work have been prescribed, the employer only has to pay for the basic cost, i.e. lenses and frames, which adequately correct the vision defect affecting VDU work. If the employee wants special frames or glasses which perform other functions, then the employer must still pay the basic cost, but the employee would have to make up the difference.

Where a number of employees are found to require corrective appliances, increasingly an online opticians will offer a corporate company plan to provide to specification the required glasses for VDU use.
