Serious eye infections can occur if contact lenses are not looked after properly
The contact lens rests on the eye and so eventually get a build up of protein, lipids
and other deposits that collect on the lens. These deposits can cause potential breeding
ground for bugs and so can get inflammation or infections if not cleaned properly.
Also cleaning will help prevent contact lens discomfort.
Daily contact lenses minimises risks as they are thrown away after one use.
Monthly contact lenses need to be cleaned after each use.
Always wash hands before handling contact lenses.
Extended Wear contact lenses
These are designed to be left in overnight - and so there is more potential for build
up of material or infectious bugs. Therefore they have to be replaced at recommended
Sometimes extended wear contact lenses may be used to wear during the day - and take
out at night.
This has advantage of having higher oxygen level but will still need to clean lenses
like regular contact lenses.
The advantage of extended wear is not having to handle lenses daily. Also for convenience
like if need to stay overnight away from home - or hygiene difficulties such as outdoor
camping where it can be harder to wash hands in order to safely handle the lenses.
Its always best to have your own spectacles with you - just incase you need to take
contact lenses out in an emergency or if eye problems occur that prevent you wearing
contact lenses. Can be essential if you are driving. Worth keeping an up to date
pair of glasses in your car.
How To Clean Contact Lenses.
Your eye care professional will recommend the correct solutions and methods of cleaning
contact lenses and disinfecting.
Always wash and dry your hands before touching contact lenses.
The Rub and Rinse Method.
Rub the contact lenses with the cleaning solution and then rinse it - which will
wash the debris away. This mechanical action is very effective in cleaning.
Finally store them in the correct solution to disinfect it.
Do not forget the contact lens case needs to be kept hygienic and replaced at regular
The contact lenses need to be thrown away at the recommended intervals. Otherwise
build up of materials from the eye occurs making it harder to keep the contact lenses
clean beyond the time recommended. The debris accumulated can be breeding grounds
for bugs and therefore not replacing contact lenses at recommended times increases
risk of eye infections.
Some contact lenses solutions are "no-rub" contact lens solutions.
However these products significantly clean your lenses if you rub your lenses while
rinsing them with the solution.
Multipurpose Contact Lens Solutions.
The multipurpose solutions both cleans and disinfects contact lenses.
Always use fresh multipurpose solution each time you store your lenses. Do not top
off existing solution as it can reduce the disinfecting power leading to lens contamination
and risk of serious eye infections.
Sometimes the contact lens case itself can be unclean and forgotten about . So its
also very important to keep your contact lens storage case clean. Rinse this and
allow it to air dry upside while you are wearing your contacts. This reduces the
risk of contamination.
Water and contact lenses
Do not use water to store contact lenses as it is not a disinfectant. Even purified
water can contain bacteria, fungi and pathogens that can grow on lenses causing serious
eye infections that can lead to vision loss.
For swimming, best to use disposable contact lenses to throw away or use water proof
swimming goggles. Or trying using prescription swimming goggles to prevent eye infections.
