Rigid Gas Permeable (RGP) Contact Lenses
Rigid gas permeable contact lenses (RGPs) are more durable and
resistant to deposit buildup. 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.
Disposable (Replacement Schedule) Contact
The majority of soft contact lens wearers are prescribed some
type of frequent replacement schedule. “Disposable,” as defined by
the FDA, means used once and discarded. With a true daily wear
disposable schedule, a brand new pair of lenses is used each day.
Some soft contact lenses are referred to as “disposable” by contact
lens sellers, but actually, they are for frequent/planned
replacement. With extended wear lenses, the lenses may be worn
continuously for the prescribed wearing period (for example, 7 days
to 30 days) and then thrown away. When you remove your lenses, make
sure to clean and disinfect them properly before reinserting.
