Okay, that's a slight exaggeration - I still bump into loads of stuff! ;) Jokes aside, I have been wearing contact lenses since 1995, and this particular brand since its launch c.2004.

Acuvue Advance are fortnightly-disposable lenses for daily wear: I moved from monthly ones, back in the days when most contact lenses were bought at huge expense for a full year of daily wear! I was always too scared that I'd damage them. That remains the one issue with these: it's still quite easy to nick the edge a little (maybe my nails are too long) - very difficult to spot, but the irritation to your eye is like razor wire! Of course, same problem is true of any lens.

That's one reason I've stuck with 2-weekly disposables rather than switch to dailies: with these, there's always a new pair ready to switch to! There's also no problem with popping them in and out over the course of the day, unlike dailies. I have tried those, but found them very thin in comparison to these and just too fiddly and easy to tear for me - presumably coming the other way you'd find any longer-term lenses rather thick.

These aren't very long-term wear lenses: if you need truly all day (or more) wear, higher-oxygen permeability ones are available but I don't really care to have my lenses in all day/night in any case - largely because my prescription is getting too high for comfortable reading.

Over those 16 years (!) I've been very fortunately not to have any eye problems at all. A large part of that is just hygiene: treat your lenses well, get (and use!!) decent solution (I use OptiFree no rub), and change them when recommended. Or as I've found, three or even four weeks - albeit not of full-time wear - and I still find these lenses perfectly comfortable. I can actually 'feel' when they need changed, as they make my eyes feel tired - but never gritty - more quickly. A fresh pair, though, and I can sit easily for 12-14 hours without discomfort.

The lenses themselves are available nearly everywhere (including supermarkets these days!) and come in boxes of six (all of the same strength) with each lens in a little blister pack with some solution - that liquid stings my eyes a bit, so do rinse with your usual saline solution before first use! They're blue-tinted just enough to be easy to see - at least if you're not as blind as me!! - and have a subtle 1-2-3 print to tell if they're inside out (no, you can't see it when they're in! ;)). They do only fit comfortably one way, though, so important to get it right.

There are both cheaper and more expensive lenses out there, with varying pros/cons depending on your personal requirements, but for me it's a case of "if it ain't broke..."! Recommended.
