Apr 22, 2024 · Rigid contact lenses, also known as gas permeable or GP lenses, are a type of contact lens made from a rigid, durable material. Unlike soft contact lenses, which are made from a flexible hydrogel or silicone hydrogel material, rigid lenses are composed of a rigid plastic material that allows oxygen to pass through.
- What Makes Gas Permeable Lenses Different? Gas permeable contacts were first introduced in the late 1970s; they are actually a newer technology than soft lenses.
- Adapting To RGP Lenses. So why doesn't everyone wear gas permeable lenses? Primarily because soft lenses are instantly comfortable, and GP lenses require an adaptation period before they are as comfortable as soft contacts.
- The Benefits Of RGP Lenses. Gas permeable contact lenses offer some outstanding benefits over soft lenses. For one, because GP lenses are made from a firm plastic material, they retain their shape when you blink, which tends to provide sharper vision than pliable soft lenses.
- Niches Where GP Contact Lenses Excel. Though they are less popular than soft lenses, gas permeable contacts are the best choice for many individuals, including
Aug 28, 2024 · Soft lenses offer flexibility and comfort, while rigid lenses provide sharper vision and durability. Factors to consider include replacement frequency, care level, and comfort of fit. Consult with an optometrist to determine the best lens for your needs. Let’s dive into the pros and cons of soft and rigid contact lenses.
May 19, 2022 · Disadvantages of soft contact lenses. Disadvantages of soft contact lenses include the risk of tearing a lens and less oxygen getting to the cornea than with RGPs. Some patients experience more dryness with SCLs. Rigid gas permeable contact lenses. RGPs, on the other hand, allow more oxygen to the cornea by the tears flowing under the lenses.

- Summary
Gas permeable contact lenses (GP) or rigid gas permeable contacts (RGP) are hard contacts. They’re made of a firm plastic material that allows oxygen to pass through to the eye (oxygen-permeable lenses). Old-fashioned hard contacts were made of polymethyl methacrylate (PMMA). One drawback of PMMA is that it doesn’t let much oxygen pass through. Now...
Eye care professionals recommend gas permeable contacts for many reasons. Advantages of GP lenses include:
Because gas permeable lenses are customizable, they can correct a range of refractive errors, including: 1. Myopia(nearsightedness) 2. Hyperopia(farsightedness) 3. Presbyopia (age-related farsightedness) 4. Astigmatism Other conditions where RGP lenses may be beneficial include:
Hybrid contacts combine the optical clarity of a GP lens with the comfort of soft lenses. Hybrid lenses have a center of gas permeable material surrounded by an outer ring of soft lens material. This type of specialty contact lens is considered the best of both worlds. Hybrid lenses were created to overcome discomfort, the primary barrier preventin...
Rigid gas permeable contact lenses cost about $35 to $95 per lens. A yearly supply costs around $70 to $190 for a pair if you replace them annually. Factors that may affect the cost include: 1. Bifocal or multifocal lensestypically cost more than single vision 2. Eye doctors usually charge more for GP lens fittings because they’re personalized 3. Y...
Gas permeable (GP) or rigid gas permeable (RGP) contact lenses offer many benefits compared to soft lenses. They also have some limitations. GP lenses are made of durable plastic that allows more oxygen and moisture to reach your eyes. This offers clearer vision and a lower risk of eye infections. Compared to soft lenses, GP contacts take more time...
Feb 27, 2019 · These design changes make modern rigid GP lenses more comfortable and easier to get used to than old-fashioned hard contacts. They also help GP contacts stay more securely on the eye when worn during sports and other activities. RGP lenses also provide better vision, durability and deposit resistance than soft contact lenses.

Oct 21, 2020 · 3) RGP lenses offer superior vision quality. RGP lenses can provide sharper vision correction than soft lenses for a few different reasons. First of all, they won’t dry out and fluctuate in shape the way soft lenses can. Gas permeable lenses are custom-made to have a smooth surface and hold their shape on the eye.
