Toric Vs. Gas Permeable Contacts

If you have astigmatism, any pair of contacts you choose will be toric contacts, as toric lenses are specifically designed to treat astigmatism. Meanwhile, gas permeable contacts are a common alternative to traditional soft lenses, and choosing between these two types is a matter of understanding the benefits as well as the disadvantages of toric gas permeable contacts.

Astigmatism

• Toric contacts are specially designed to treat astigmatism, and they can be made as either soft contacts or gas permeable contacts.

Care

• Gas permeable contacts are easy to care for because they are less prone to bacteria build-up than soft contacts. They also tend to last longer, though they may become scratched over time.

Comfort

• Because gas permeable contacts are hard, they require an adjustment period before they feel comfortable.

Durability

• The gas permeable contacts are more durable than soft contacts, as they are less prone to tearing.

Visual Acuity

• Many individuals--with or without astigmatism--find that gas permeable contacts offer sharper vision because their rigidity helps them keep their shape when you blink.
