Rigid gas permeable (RGP) contact lenses are known for sharp vision, durability, and reliable correction for certain vision needs. They were developed as an improvement over older hard lenses made from PMMA, a material that did not let oxygen pass through to the cornea. RGP lenses allow more oxygen flow and keep their shape on the eye, which can help give clearer vision for wearers who need precise optical correction.

RGP lenses can work well for people with higher prescriptions, irregular corneas, or vision conditions that soft lenses do not correct as clearly. They also tend to last longer than soft lenses when cleaned, stored, and handled properly. Learning their benefits, drawbacks, adjustment period, and care routine can help you have a more informed conversation with your eye doctor.

What Are Rigid Gas Permeable Contact Lenses? 

RGP contact lenses, also known as GP or oxygen-permeable lenses, are crafted from durable, flexible plastics that allow oxygen to pass through to the cornea. Unlike soft contact lenses, RGPs maintain their shape on the eye, providing sharper vision and correcting most astigmatism and other irregularities. 

These lenses are tailored to the shape and health needs of the individual’s eyes, often resulting in a more custom fit. Rigid gas permeable contact lenses are also known for their ability to resist deposits and be less likely than soft lenses to harbor bacteria, making them a healthier option for long-term wear.

How Often Should You Clean RGP Lenses? 

RGP contact lenses require regular cleaning and care to maintain their effectiveness and prolong their lifespan. It is recommended to clean these lenses daily with a specific RGP cleaning solution to remove lipid and protein deposits. After cleaning, the lenses should be rinsed and stored in a soaking solution overnight. Proper handling and regular enzymatic cleaning, usually once a week, also help prevent surface buildup and ensure optimal lens performance.

How Long Can You Wear RGP Lenses in a Day?

The duration RGP lenses can be worn in a day depends largely on the user’s adaptation to the lenses and their eye health. Initially, wear time may be limited, but with regular use, most individuals can wear their RGPs for up to 14 hours a day. It’s important to increase wearing time gradually to allow the eyes to adapt comfortably. However, any signs of discomfort or dryness should prompt a reduction in wear time and consultation with an eye care professional.

How Long Do Rigid Gas Permeable Contact Lenses Last? 

RGP contact lenses are known for their durability. With proper care, a single pair can last up to two years, which is much longer than most soft contact lenses. This longer lifespan can make RGP lenses a cost-effective choice for many wearers. Regular checkups with an eye care professional are still needed to confirm that the lenses fit properly, correct your vision well, and do not cause eye irritation or damage.

What Are the Benefits of Using RGP Contact Lenses?

RGP contact lenses have several benefits, including:

• They can give sharper vision and better correction for astigmatism compared to many soft lenses.
• They are made from sturdy materials, so they are less likely to tear and can last much longer with proper care.
• They allow oxygen to pass through to the cornea, which helps support healthy eyes.
• Their longer lifespan can make them more cost-effective over time.
• They are less prone to protein and lipid buildup, which can help keep the lenses cleaner and more comfortable.

What Are the Disadvantages of RGP Contact Lenses?

Here are some possible drawbacks of using RGP contact lenses:

• They can feel uncomfortable at first while your eyes adjust to the firm lens material.
• They need consistent cleaning and proper care every day.
• Their smaller size and rigid shape can make them easier to dislodge from the eye.
• Some wearers need more time to get used to the feeling of RGP lenses.
• The upfront cost can be higher than some types of soft contact lenses.

Can You Shower With RGP Lenses?

No. It is generally advised to avoid wearing RGP contact lenses while showering. The water can carry contaminants that may adhere to the lenses, potentially leading to infections or lens damage. Shower water can also cause lenses to dislodge and potentially be lost. To maintain optimal lens health and eye safety, remove RGPs before any activity involving water.

Can You Sleep In Rigid Gas Permeable Contact Lenses?

No. Sleeping in RGP contact lenses is not recommended unless specifically prescribed by an eye care professional for overnight wear. Wearing RGPs while sleeping can restrict oxygen to the cornea, increase the risk of eye infections, and lead to discomfort or corneal neovascularization. For those requiring lens wear at night, specific designs and materials made for extended wear should be considered.

Can I Use Eye Drops With Gas Permeable Contact Lenses?

Yes, you can use eye drops with RGP contact lenses, but it’s important to choose the right type of drops. Not all eye drops are suitable for use with contact lenses. It is advisable to use rewetting drops or artificial tears that are specifically labeled as safe for use with rigid gas permeable lenses to prevent any adverse effects and ensure comfort.

How Much Do RGP Lenses Cost?

The cost of RGP contact lenses varies depending on the prescription, lens material, and any custom features required. Generally, a pair of RGP lenses can cost between $100 to $300. While this may be higher than some soft lenses, the longer lifespan and fewer replacements make RGPs a cost-effective solution over time. In addition, the cost can vary based on the provider and geographic location.

Are RGP Contact Lenses Worth It?

For many individuals, RGP lenses are indeed worth the investment. They offer numerous benefits, including enhanced visual clarity, durability, and better eye health due to their resistance to buildup and high oxygen permeability. Although there is an initial adjustment period and the cost can be higher upfront, the long-term savings and superior visual performance make RGPs an excellent choice for those suitable for this type of lens.

Takeaway

Rigid gas permeable (RGP) contact lenses can be a strong choice for people who need sharp vision, durable lenses, and higher oxygen flow to the cornea. They do require regular care and an adjustment period, but their long lifespan, clear optics, and potential eye health benefits can make them worth discussing with your eye doctor.

The right choice depends on your comfort, lifestyle, prescription, and vision needs. An eye care professional can help confirm if RGP lenses are a good fit for your eyes.
