The solution is also helpful in removing small elements and debris from the lens's surface. This function is very important because it assures you that there will be no irritants that can cause infection to your eyes. Also, saline solutions are used to maintain water balance, especially to the softer types of contact lenses.

There are three basic kinds of saline solution. These are the commercial solutions with preservatives, the commercial solutions without preservatives, and the homemade solutions that also do not have preservatives at all.

Some contact lens saline solutions use preservatives to aid in slowing the propagation of bacteria in the lens. The saline solutions, especially the ones with preservatives, should be used according to the guidelines that come along with it.

For people who happen to have infections to the preservatives used, the sterile or the preservative-free saline solutions are the one they should pick. But these kinds are easily contaminated than its counterpart. Its users should be stricter in following the instructions.

Although it is a fact that some people produce homemade contact lens saline solution, it is actually not advisable to use. Distilled water mixed with enzyme tablets is not good enough. The saline solution must be manufactured in a highly disinfected environment to be germ-free.

Again, before using commercial saline solutions, you have to read the label. For starters, do not overuse the solution. You have to replace it in a regular basis to ensure that you are getting the best possible protection.

Contact lenses come in a case and are covered in the solution when bought. Once the lenses are taken out of the case, throw the solution away. Rinse the case and air-dry it. When the contact lenses need to be placed back in, put in a fresh saline solution.

Always check out the expiration date on the bottles. Dispose of the ones that are way past the date, even if they are not opened yet. Change the saline solution, as well as your contact lenses as prescribed by your practitioner.

Before using a pair of lens, always disinfect. Even if the lenses are sitting in a saline solution overnight, you are still not assured that it is 100% free from bacteria. Use another splash of fresh saline solution to do the trick.
