Gas permeable contacts

moderate congenital glaucoma case
RGP lenses are rigid, but the plastics they are made from are more flexible than conventional hard lenses. Modern RGP lenses allow more oxygen to pass through the eye. Sometimes they are referred to as ‘Oxygen Permeable’ lenses. Although soft lenses are fitted more regularly, gas permeable lenses are excellent for certain prescriptions

Rigid gas permeable contact lenses (RGPs) are more durable and resistant to deposit buildup, and generally give a clearer, crisper vision. Though less popular than soft contact lenses, gas permeable contact lenses generally provide sharper vision — especially if you have astigmatism or certain higher- order aberrations. They tend to be less expensive over the life of the lens since they last longer than soft contact lenses. They are easier to handle and less likely to tear. However, they are not as comfortable initially as soft contacts and it may take a few weeks to get used to wearing RGPs, compared to several days for soft contacts
