    Oral contraceptives increase your risk of blood clots. A small blood clot that forms in the left side of your heart can commonly go to the arteries that supply the eyes causing central retinal artery occlusion(CRAO) or branch retinal artery occlusion(BRAO).

    This is usually the reason women on birth control pills are cautioned to be aware of vision changes.

    I can’t think of (nor find any documentation of) a reason they would affect contact lens wear though…

    I am on bc and I have contact lenses and I never have "blurred vision" problems. I don’t know where you heard this.

    This is not true any more than a woman’s monthly cycle would affect her vision/contact lenses, because BC pills are simply manipulating her hormones that she already has.

    wow..actually after taking birth control for about 1 week i could no longer put my contact lenses in…i tried birth control once again 5 months later and the same thing happened.
    it actually says that you may NOT be able to put your lenses in on the warnings section of your prescription pamphlet
    i took YAZ the first time and orthotrycycline the second time
    PLEASE DON’T BE IGNORANT

    For those of you who are saying this is not true and that they have no affect on contact lens wear, take a look at the pamphlet that came with your birth control pills. It will clearly state in the list of side effects: ‘difficulty wearing contact lenses’. I have been taking the pill for almost 2 years now and have never had difficulty putting them on, but there are times throughout the day when my vision becomes blurred and it takes me a few seconds and quite a bit of blinking to fix it.

    and to second joan’s comment… DON’T BE IGNORANT! and please take the time to research and learn about what you’re putting into your body.
