What are semi soft or RGP contact lenses?
Semi-soft lenses are made of slightly flexible plastic that allows oxygen to pass through to the eyes. The advantage with these lenses is the vision which may be sharper than with soft contact lens. They are especially useful in astigmatism, keratoconus and post-refractive surgery. They are easy to put on and care for. Semi soft lenses are durable (1-2 years) and are available in various tints and even as bifocals.
