The wear of contact lenses can be extended by careful cleanliness. This refers to the cleaning and hygienic handling of both the lens case and the lenses themselves. Regular cleaning with the right types and amounts of solution will ensure that the monthly ones or the yearly ones are kept in good working condition and offer the optimal convenience to the patient. The method used to clean them should also be applied every time in order to ensure that they are cleaned to the maximum.
Daily disposable lenses are however an option to those who may not be able to clean them due to time constraints. Daily disposable ones are discarded after one use. Thus the next day the patient will automatically be inserting a clean lens into his or her eyes. According to http://www.contactsjudge.com/, this ensures to greatly reduce the chance of infections that can occur from lenses that have not been cleaned properly.
Multipurpose solutions that have been created to clean the lens have also shown a reduction in the problems caused by unclean lenses so far. A silver impregnated lens case can help to eradicate any microbes that can potentially be harmful to the eyes.
Further research is being conducted into embedding antimicrobial agents that will allow for better hygienic wear of lenses.
The cornea of a rabbit eye cannot be affected by selenium molecules. Thus these may be added to the contact lenses in the future to reduce bacterial colonisation. A substance known as octylglucoside can be used as a contact lens surfactant to decrease bacterial adhesion. These methods are of particular interest to the optometrists and also to the manufacturers of the lenses themselves as they do not rely on the patient’s compliance in order to reduce the effects of bacterial colonization.
Bionic lenses are being developed which allow images to be suspended in front of the wearers eyes. These use build in electric circuits and they can harvest radio waves for their electric power. A mobile device can then display the information thus the small size display problem will be overcome. There will be devices embedded into the lenses themselves as well. These are at the moment being considered as a head-up display for mostly pilots or gamers.
It is recommended however that an eye test and a contact lens evaluation be carried out before trying on any of the lenses. This is because any underlying medical conditions existing before hand could be cleared off. It is not everyone who is suitable for contact lens wear. Even the ones used for cosmetic purposes should be got from qualified and professional contact lens fitters and suppliers.
