Contact Lens Care Products
Cleaners
Cleaners are used to remove unwanted deposits such as oils and
proteins. If these types of deposits are left on the contact lens it may lead
to discomfort, eye irritation and decreased contact lens life. Cleaning is carried out by either
gently rubbing all surfaces of the contact lens with a multipurpose contact lens solution or placing the contact lens in a contact lens case filled with a no rub multi purpose cleaning solution. Contact lenses should then be rinsed with a multi purpose solution prior to inserting in eye.
Storage & disinfecting solutions
These are usually a multipurpose solution that stores, disinfects and
cleans the contact lenses. Storage solutions are used to maintain the
physical characteristics of soft contact lenses during storage. They
are also used to rinse off the contact lens surface after the cleaning
process to remove any loosened contaminants and cleaning solution. If
a soft contact lens is allowed to dry out and is then re-wetted, provided
that no damage has occurred to the contact lens, it will rehydrate well. In
fact many soft contact lenses are manufactured in the dry state and then
hydrated.
Disinfectants prevent infection by significantly reducing the number
of "bugs" present on the contact lens such as bacteria and fungi. The contact lenses
are soaked in a specially designed chemical disinfection solution
usually overnight to ensure absolute disinfection even though the eye
has a very good natural defence against contamination. In most cases
the same solution is used for storage and disinfection.
From time to time, especially in dry or air conditioned environments
the eye loses tears to the atmosphere by evaporation, as do soft
contact lenses lose some of their water content to the atmosphere. The normal
tear levels cannot cope in keeping the contact lens moist, so lubricating or
re-wetting drops are used to improve the comfort and maintain good
vision.
