Gas Permeable (GP) Contact Lenses

Look at the Benefits of Hard Contacts Lenses

Gas permeable contacts, also called rigid gas permeable (RGP) contact lenses, can be an excellent alternative to soft contacts. Many people mistakenly think of hard contact lenses as an old-fashioned, obsolete type of eyewear that was replaced by flexible soft contacts. However, GP lenses of today are not the same as the ones of the past – and hard contacts are making a definite comeback!

Although soft contacts are still more popular, hard lenses have many unique benefits and are more suited for particular vision conditions. Our eye doctor fits many patients with these advanced contact lenses in Ozark, AL.

What are hard lenses made of?

GP contact lenses are composed from durable compounds that contain silicone, which allows oxygen to pass through and reach your eyes. In effect, they let your eyes breathe. This advanced, modern material is the primary reason why hard lenses offer so many advantages.

How does it feel to wear hard contact lenses?

Many of our patients who are looking into wearing rigid gas permeable lenses contact lenses in Ozark, AL, wonder if they will feel the hard discs in their eyes. At first, people do generally feel the presence of these hard lenses. Yet, that’s only at the beginning. After a short adaptation your eyes and eyelids will get used to them – and then you won’t sense anything. This is because GP lenses have a smaller diameter than soft contacts, so you will feel the edges temporarily. After a short time though, many people claim that hard contact lenses offer superior comfort to any other lenses they’ve ever worn.

What are the advantages of rigid gas permeable contact lenses?

 

  • Smaller size = Healthy cornea

 

The smaller diameter of hard contact lenses covers up less of the cornea, which promotes healthier wearing.

 

  • No water content = Cleaner lenses

 

Without water, GP lenses are less prone to the build-up of bacteria and protein deposits. This lowers your chances of eye infections and keeps your lenses cleaner.

 

  • High oxygen permeability = Healthier Eyes

 

This leads to increased health, safety, and comfort of hard lenses, and a reduced risk of eye problems. Many rigid contacts on the market today actually permit more oxygen to reach the cornea than most soft contacts.

 

  • Durable and long lasting = Cost-effective

 

The life span of rigid contacts is much longer than soft lenses. Because they are hard, you don’t need to worry about tearing them, and they usually last at least a year. This also makes them cost-effective.

What vision conditions do hard contact lenses treat?

Anyone can wear rigid gas permeable contacts, but there are several vision conditions for which hard lenses are particularly appropriate.

Dry Eye Syndrome

When you blink while wearing rigid contacts, they hold their shape and move on your eye. This movement facilitates the smooth flow of healthy tears under the lens, thereby helping to prevent and treat dry eye. Also, the lack of water in GP lenses makes it impossible for them to dry out, which is a common cause of blurry vision when wearing soft contacts.

Astigmatism

Many people, especially when they have astigmatism, achieve sharper vision with hard lenses. When performing eye exams, our eye doctor has found that a lot of patients with astigmatism see much crisper and clearer than they ever did with soft lenses.

Do hard contact lenses work for myopia control in kids?

Yes! Myopia control can be an added bonus for children who wear rigid gas permeable lenses. Research suggests that wearing hard lenses may slow the progression of nearsightedness in some kids.

What are ortho-k lenses?

Orthokeratology, or ortho-k, is a method of vision correction that involves wearing specialized GP lenses while sleeping. Ortho-k reshapes your cornea gently so you won’t need to wear prescription eyewear during the daytime in order to see clearly.
