Importance of Contact Lens Solution
Contact lenses are prone to be affected by micro organisms and deposits, as with all other materials and if these bad elements are not properly removed, it may result in contaminating the lenses, thereby causing discomfort to the eyes. So, the contact lenses should be regularly cleaned and maintained.
Contact lenses should not be cleaned with ordinary tap water since it contains chemicals, minerals and other particles apart from micro organism that are harmful for the eyes. Even home made saline- even if it is purified and distilled - should not be used for cleaning the contact lenses because it may involve designated amount of pieces of ingredients. Thus, contact lens solution which is specifically intended for this purpose alone must be used.
These solutions are specially designed such that they protect the moisture in the eyes and prevent lenses from dehydration. Most of the solutions are available without the preservatives and contain peroxide, which is good for disinfecting. So a good contact lens solution is the one that suits all types of lenses, enhances the movement of the lenses and is specially formulated to lubricate contact lenses.
The contact lens solution should be capable of removing protein, prevent calcium deposits and also kill germs. The contact lens solution should be such that it lubricates and moistens the lenses thereby relieving the eyes from irritation from the dirt, dryness or smoke, which are all hazardous to the eye. Contact lens solution should be selected to suit people who have sensitive eyes.
Contact lens solution also plays a great part in maintaining the water balance of the lenses. The contact lens solution is available with and without preservatives. To be free from germs, the contact lens solution must be manufactured in highly disinfected environment.
When the contact lenses are taken out of the case for use, the solution should be discarded and when the lenses are placed again, a fresh solution must be used. The contact lens solution must be changed periodically as advised by the medical practitioner. It is mandatory that the contact lens solution is approved by the FDA and manufactured by reputable companies.
The contact lens solution should never be reused. Most of the users of contact lenses top off the liquid, which is adding a little more quantity of the solution to the already existing used solution and this should never be done. The solution should be changed everyday.
The eyes are far more precious than a bottle of contact lens solution and therefore, there should be no compromise on the quality of the contact lens solution.
