Must have, but you must know how to use it.
My wife bought me this for my contact lenses and I was curious and a bit worried based on the reviews I've read.  I waited to write a review until I used it in several scenarios.  The package I received had 2 large bottles and 1 &#34;TSA friendly&#34; 3oz bottle plus 2 of the lens holders.  I wear Air Optic Multifocals, a &#34;open a new pack once a month&#34; disposable.<br /><br />From the picture you will notice that the lid is red and there is a red/orange warning label around it.  This is to make sure it stands out to you because you cannot use this like you use normal lens solution.  This is a special formula and special holding container that you put your lenses in overnight and it cleans them with a &#34;bubbling&#34; action, which really does bubble away.  The hitch is that you have to have the lenses in for a recommended period of time so the solution neutralizes.  You cannot do a quick soak or put them in for a couple of hours...once they are in you are committed.<br /><br />So first things first, this stuff is absolutely fantastic at doing exactly what it advertises.  If you leave it in overnight (they say 6 and a half hours, but it really needs more like 8), your lenses feel as fresh at the end of the month as they do at the start.  This was really key to me because for the first 2 1/2 years of wearing lenses, the end of the month for new lenses was something I really looked forward to because my lenses bothered my eyes more and more over the course of the month.  This fixed that - they feel as good on day 30 as day 1.  I won't live without this product again.<br /><br />However, you need to know that it does not replace regular lens solution.  You need regular solution for the quick soak, the popping out a lens to clean it, etc.  This is a better cleaner, not a new solution.  Though my eye doctor's office didn't really do a good job of covering this in the &#34;consult&#34; I paid for, my personal take is you need a product like Clear Care for routine cleaning, you need regular lens solution for short soaks and those times where you take lenses in and out, and you need a good rewetting solution for those days where lenses are being annoying.  This is part of a total solution.<br /><br />If you don't pay attention to which bottle you grab, or you ignore the warnings, you will pay a hefty price.  I accidentally grabbed this when cleaning a lens real quick one day instead of my regular solution, which was totally my fault - I was inattentive.  The bottle is covered in more warnings than you can ever imagine and those warnings don't understate the consequences...but I rinsed my lens and popped it back in my eye.  The pain was easily in the top 10 pain moments of my life, and the irritation and soreness lasted for a couple of days.  They are dead serious, you have to let them soak.<br /><br />The other thing to know is I don't recommend for travel unless you can give long soak times.  I travel on business a lot, and frequently end up taking people out to dinner/entertaining, followed by getting up early.  Despite the bottle recommendations on soak time, I've let it run an hour past and still experienced anywhere from mild to heavy burning.  The heavy burning was after 7.5 hours of soak on my most recent business trip, and it was about 50% of the pain felt in the &#34;rinsed and put back in&#34; incident.  There seems to be some variables in the soak time, and at home I tend to soak at least 8 hours without problems.  For future business trips, I'll just take the regular holders and regular solution.<br /><br />In summary, I consider this stuff a must-have, but it has a specific purpose and role.  It is not a jack of all trades, it has a job.  That job extends the life of your lenses and completely improves their comfort, but understand the limitations and whatever you do, do NOT underestimate the warnings.
