Are gas permeable contacts better than soft?

Why is RGP better than soft contact lens?

Rigid gas permeable contact lenses have several advantages, including: They are made from durable material, are easier to handle, and less likely to tear. Hard lenses are resistant to deposit build-up, thus providing crisper, clearer vision. They are longer-lasting and therefore less expensive than soft contacts.

What is an advantage of gas permeable contact lenses?

Advantages of gas permeable lenses
