Contact Lens Care
Two general
types of contact lens :
- Soft
- Rigid Gas
Permeable (RGP)
Soft Contact
Lens
They are
usually disposable and can be discarded after a
short period of use (ie. Dailies, Bi-Weekly or
Monthly). A fresh pair of contact lens would mean
less chance of eye infection, less cleaning, and
more comfort, especially for people whose eyes
naturally produce more protein that clouds lens.
Made from soft plastic, soft contact lens are very
comfortable as they hold more water than rigid gas
permeable lens. Many of the new materials provide
ultraviolet (UV) protection. While most people
choose soft lens because of their benefits, there
are also some disadvantages. Soft lenses easily
absorb pollutants such as lotion or soap from your
hands that can irritate your eyes. They are also
more fragile than hard lenses and can rip or tear
while cleaning them.
Rigid gas
permeable (RGP)
 Being more
rigid than soft lens, RGP lens are hence more
durable for an active user. They are made of
silicone polymers, allowing oxygen to circulate to
the cornea of the eye. RGPs maintain their shape
better and offer clearer vision with certain types
of corrections. They are also extremely durable and
easy to take care of. Deposits from tears and
outside irritants are not as easily absorbed as
compared to soft contact lens.
