Do they make hard contacts anymore?

Many advances have been made to hard contact lenses since the 1970s to create a healthier lens for eyes. They are still regarded as hard contact lenses because they maintain their shape on the eye. Rigid gas permeable contacts, also called GP or RGP lenses, have many advantages beyond healthy oxygen flow.

What is another name for hard contact lenses?

Gas permeable (GP) contact lenses, also known as rigid gas permeable (RGP) lenses, are hard contact lenses made of silicone-containing compounds that allow oxygen to pass through the lens material to the eye. Though not as popular as soft contact lenses, GP lenses offer a number of advantages over soft lenses.

What is the difference between soft and hard contacts?

Hard contacts, or rigid gas permeable contacts, are not as flexible as soft lenses, but they are more durable. These lenses also let oxygen flow through to your eyes, which helps increase comfort. Unlike soft lenses, hard lenses do not change shape when you put them on.

Can I use soft lens solution for hard lenses?

Care systems for rigid gas permeable, or hard, contact lenses are different from care systems used with soft contact lenses. Hard contact lenses typically require several different solutions for wetting, cleaning, and disinfecting. Never use hard contact lens care products on soft contact lenses.

Do hard contacts hurt?

Made from a sturdy plastic material (often silicone) with a rigid design, you’d think these lenses were uncomfortable. However, it usually only hurts to wear them at first or if you get debris in your lenses. Many contact lenses can restrict how much oxygen makes its way to your cornea.

What is a rigid contact lens?

Hard contact lenses Most hard (rigid) lenses are made of gas-permeable materials that allow oxygen to reach the cornea. This reduces problems that may occur when the cornea does not get enough oxygen. They correct refractive errors, including astigmatism, with no distortion. Conventional hard lenses (PMMA).

Why do my gas permeable lenses get cloudy?

When gas permeable contacts become cloudy, it’s usually due to tiny particles of dirt or debris that get stuck inside or around the lens. This can also be caused by protein buildup, which can usually be cleaned off, but if that doesn’t work, it may be the quality of GP lenses themselves.
