Perhaps some of you out there who wear contact lenses would be kind enough to share your thoughts and opinions on this subject.
Which contact lens solution and more so, which contact lens cleaning method do you prefer?
For the past 20+ years that I have been wearing contact lenses, I have always used the 1-Step Multi Purpose* cleaning solution, which has it's advantages in that you do not require any prep or special procedure to clean and store the lenses.
Just remove the contact lenses, fill up the storage container and place the lenses in, and within 12-hours, you're done.
On the other hand, I was recently advised to try out the Hydrogen Peroxide "chemical cleaning" method, which consists of a couple of additional steps; you have to rinse the lenses with saline first, then with the 3% Hydrogen Peroxide Solution, then place them in the cylindrical container which has a Plastic-Platinum coated disc on the bottom of it, and let it soak for 6-hours or more.
You can see the Hydrogen Peroxide solution being 'neutralized' as the chemical reaction between the platinum disc and the solution creates gasses and bubbles, etc.
It may be too soon to tell, but my initial impression is that the Peroxide method seems to clean the lenses more thoroughly - they feel a lot more comfortable in the eyes than the ones that have been cleaned with the Multi-Purpose solution.
There are several differences and advantages/disadvantages to the two methods - for example:
-Multi-Purpose requires fewer steps, can be transported while in the case and can be stored in the case for almost 6-months or more.
-Peroxide method seems to actively clean the lenses (for what it's worth, you can see the bubbles) but you should not move the case around much while the cleaning is in progress and the lenses should be removed from the cleaning case by 72-hours or so after completion.
-Multi-Purpose cleaning does require that you do a 'final rinse' with pure saline solution after the cleaning process and before wearing them, to remove residue.
-Peroxide cleaning neutralizes all traces of the cleaning fluid and other impurities and you can wear them right away after 6-hours.
-Some people (I am not) are allergic to the Multi-Purpose cleaner solution (usually BASF TETRONIC 1394), but the Peroxide is turned into pure saline, so no worries there.
-Not that a few dollars matter to me, but as a rule, the Hydrogen Peroxide cleaning solutions are typically about 25% cheaper than the Multi-Purpose formulas.
There are other things, but these are the few that come to mind at the moment.
The Multi-Purpose contact lens cleaning solutions have some pros when it comes to storage and ease of initial use, but it seems that the Peroxide cleaning system has a few advantages in terms of comfort and moisture retention. Again, it is too soon to tell for me, since I just started to use the Peroxide method, but I would appreciate any ideas or comments.
There are other cleaning methods, such as heat and I think someone even sells some sort of bizarre microwaveable contact lens cleaning product (No Thanks!) - I will not be trying that.
Thanks,
-Nick
*My optometrist recommended the Alcon Opti-Free RepliSH brand to me over two decades ago, which is what I have been using ever since.
That one contains the BASF Tetronic 1304 and PolyQuad(ternum) cleaners.
