General:
Ever since I found peroxide solutions, I've been saved. They are the only ones that sterilize and deeply clean the lenses. I've tried both Alcon Aosept Plus and Hydraglide. Honestly, I haven't noticed any major difference. Supposedly, Hydraglide has more lubricating agents to make lens use more pleasant, but I can't confirm that there's any difference.
---- Cleaning function:
It comes with a case and at the bottom, there's a noble metal acting as a catalyst. The solution contains peroxide and lubricating substances. The peroxide sterilizes, kills bacteria, and at the same time reacts with the catalyst, which turns it into water and oxygen, with the oxygen leaving as bubbles. The bubbles also help with cleaning because they agitate the lenses and remove the biomass better. The solution needs about 6 hours and then essentially turns into water + the lubricating ingredients. While it's active, it shouldn't touch your eyes, so make sure you leave it for at least 6 hours.
---- Daily use:
I use it daily, I put the lenses in at night before I go to sleep and in the morning they're ready. Some people use other solutions every day and use this one once or twice a week for deep cleaning. Usually, before I use them, I take them out of this solution and put them in regular solution to absorb more lubricating agents because with this, they might stay a bit drier.
---- Positives:
You don't need to rub the lenses to clean them, you don't worry about bacteria or residue from your fingers when you rub them, etc. You just put them in the case, add the solution, and leave them for 6+ hours.
---- Negatives:
Other simple lens solutions can be used as eye drops or you can take the lenses out for a bit, put them in solution, and put them back in directly. You SHOULD NOT use this one like that, it has peroxide and it burns. Also, it must be used with a case that has the metal catalyst; if you put it in a regular case with lenses, it won't deactivate and will burn your eyes if you wear them. These aren't exactly negatives, it's just that its use is very specific and it's important to know that.
---- Is it suitable for all lenses?:
I've used it on hard lenses meant for yearly use, monthly, and quarterly, and not only have I never had a problem, but every time I cleaned them, they felt like new. I've read that some monthly or weekly lenses are made from softer/milder material and so they might be damaged by the peroxide. I DON'T know exactly which brands or types of lenses shouldn't be combined with this solution.
---- Colored lenses:
It says it might discolor them because peroxide is a sterilizing and bleaching agent. I've used it on crazy colored lenses and other various designs/colors I tried, and there was absolutely no problem. If the color is laminated, obviously nothing will happen. If it's a special dye, then it might react with the peroxide. But you should check that yourself to be sure.
---- Safety of use:
For those who say your eyes stung or you went to the hospital after using it, it's better to stay away from this product. You need to know how to read the instructions to use it, and you may already be blinded by the liquid if you put it in before it is neutralized!
It contains hydrogen peroxide which burns! It must be used with the special case and not with another case without a catalyst, and you must wait 6 hours (until the bubbles stop completely).
