Hi - I've noticed a few threads about women having issues with diminished sight after being on Ortho cyclen / Tri Cyclen. It also seems to be an issue that is SO hard to find any research / info on!
Anyway, I had poor vision quality when taking OrthoCyclen also (quite bad actually), and let me tell you - if you can switch to something with Desogesterel (OrthoCept or Mircette) it may help.
I realized this after struggling with poor vision for so long, then one day my doc mistakenly prescribed Ortho Cept. I waited until the last minute to fill my scrip, so I had to take it for a month. That pill didn't agree with me, except my vision was perfect after about three weeks of taking it. Didn't realize that the improved vision was a result of the different pill, until I went back on OrthoCyclen and lost my perfect vision within a couple of weeks. *cry*
I've been taking Mircette for 11 days now and I already see an improvement in my sight! I hope to be 20/20 again by this time next week!
Obviously, it may or may not work for everyone - but if the vision thing has been troublesome for you too, it might be worth a shot! good luck --
(ps - So far, I *love* my mircette (kariva!))
