Medical Forum / General / Vision / November 2004Old and new packages of Acuvue-2
Hello, I have been using lenses since 1998. So far, I only had Acuvue-2 lenses. When I had my first Acuvue-2, I thought they were monthly (it was a mistake) and I used them for 1 month, sometimes more (about 40-45 days). I had absolutely no problems with them, my view was perfect, no irritation. My opth checked recently my eyes, and everything was perfect, as she told me. I was running out of lenses, so I decided to buy new ones, still Acuvue-2. My first surprise was that the packaging had changed: I used to have only old boxes, with four lenses in each. The new package has now 6 lenses in it. However, since I have my new lenses, my eye feels irritated just a few days after (8-10 days). Worse, I cannot wear them a whole day: I used to wear lenses for something like 12-14h in a day (up to 16-18h, without any problem), and now I cannot wear them more than 6-8h. I checked up everything else, daily cleaning, lenses metrics... it doesn't help. Apparently, the new lenses are exactly the sames as the old ones. Does anyone know if something has dramatically changed for Acuvue-2 lenses with the new packagings ? > However, since I have my new lenses, my eye feels irritated just a few > days after (8-10 days).

Your email address suggests you're posting from France, so your experience there may be different from ours in the US. I've had the Acuvue 2 in my practice since mid-1999. I think they were available here before that, but not much earlier - only 6 months or so. In the US and Canada, Acuvue 2 (and the original Acuvue, released in the early 90's?) have always come in boxes of 6. I've never seen them packaged 4 to a box. > I have been using lenses since 1998.

If you aren't sleeping in them, some doctors here prescribe them as one-month lenses, although that's "off-label," meaning beyond the wearing schedule approved by our Food and Drug Administration. The Acuvue material was originally packaged as a one-year lens called Vistamarc. It had a terrible reputation for buildup and fragility compared to other "one-year" lenses. It works great for 2 weeks, and sometimes OK for 1 month. If I recall correctly, Acuvue 2 was released here in a new package, a flatter box than the old (first) Acuvue, with smaller bubble-packs, but still 6 to a box. Some of the very first lenses we got were in the larger, more cubical box, but I think that was only the trial lenses, not for retail sale. > However, since I have my new lenses, my eye feels irritated just a few > days after (8-10 days).

In the US, Acuvue 2 comes in two shapes - a tighter 8.3 base curve and a looser 8.7 base curve. People who need the 8.3 and suddenly switch to the 8.7 will experience the same symptoms you describe. Even though you said you compared the "lens metrics" and found them identical, we have to wonder if somehow you switched base curves. If your current lenses are 8.7, you'll probably find the 8.3 much more comfortable. Vistakon says that the 8.3 fits "most people." > Does anyone know if something has dramatically changed for Acuvue-2 > lenses with the new packagings ? I don't think the AV2 packaging has changed here since it was released. Regardless, I've handled several thousand of them and never noticed the change you describe. -MT > > However, since I have my new lenses, my eye feels irritated just a few > > days after (8-10 days).

You are right, I'm french. I may be wrong about 1998, as far as I can remember I had A2 since 2000, beyond 2000, I'm not that sure. > In the US and Canada, Acuvue 2 (and the original Acuvue, released in the > early 90's?) have always come in boxes of 6.

It seems to be the difference I was trying to mention. The old pack was cubical, the new one is flat. > > However, since I have my new lenses, my eye feels irritated just a few > > days after (8-10 days).

I'll try to see that tonight. Thanks for the answer. > > Does anyone know if something has dramatically changed for Acuvue-2 > > lenses with the new packagings ?
