Several studies have been conducted across America regarding the use of contact lens, and how it can affect the health of its users. The results are almost synonymous to each other, that contact, no matter what type it is and what material it is made up of, they can harm the eyes because of the bacteria called pathogenic protozoa that settles on the contacts. High level of this bacterium can cause serious eye infection, and even blindness.
However, studies also show that a slight modification and differences in the formulation of any solutions can make a big difference among patients eye health. Contemporary multipurpose solutions or MPS have developed over the past couple of years. The formulation of this solution has been the standard for contact lens solutions for quite some time.
The previous versions of these solutions mainly contained thimerasol and chlorhexidine, both chemicals are very strong cleaning, disinfecting and sensitizing agents. However, because it is so strong it usually harms the eyes and cause irritations like red eyes which can be really uncomfortable.
The new breed of contact lens solutions today on the other hand contains different type of cleaning agents and preservatives. Polyquad or also known as polyquaternium-1, Aldox or myristamidopropyl dimethylamine and PHMB or polyhexamethylene biguanide are milder disinfecting agents, and the use of these don’t really cause any major forms of eye irritations.
Now the question is which type of solutions is really better in disinfecting the lenses without causing eye health problems to the contact lens users.
There are just simple ways to answer this question, all you have to do is to synthesize the answer you get and understand how it really works to provide your eyes the comfort and vision aid you need from wearing contacts.
The first thing you can do is to know the difference. Determine which type has been effective and worry free for you. Eye doctors may recommend something and may still say that all solutions really work, but the thing is that you have to find which one works best for you. The effect of the solution differs from in every person, it may work wonders for you and can be nightmare for others.
