    Hi, I recently went to the optometrist and she put a yellowish eyedrop into my eyes. The thing is, I felt something cold on my eye then the eye drop so, I was wondering if she touched my eye with the eye dropper...I went because I had scratched my eye so I was wondering if fluorescein sodium, is antibacterial, I don't want to get an infection or anything elce.

    It's not antibacterial. Check out the Wikipedia article on it, just type in "Fluorescein". At the bottom there's a section entitled "Ophthalmic applications".

    Fluoroscein is commonly used by ophtalmologist in order to check if there is no scratch or ulceris of your cornea.
    Fluoroscien is a very strong pigment, beware to not put it on your clothes

    If you noticed a blue-ish light the doc used just after applying the fluorescein, it was ultra violet. Fluorescein is a fluorescent dye, that is, it 'glows' under UV. Yes, it's safe, and no, the UV will not harm your eyes at the wavelength they use.

    I don't know if your optometrist touched your eye or not but the cold feeling is normal when administering fluorescein and doesn't necessarily indicate contact.

    Plus if the abrasion was bad then she would have prescribed antibiotics, I wouldn't worry too much unless it gets worse.

    But I'm not a doctor!!! Don't sue!!!

    The eye is naturally antibiotic too, tears provide an unfavorable environment for growth. This is a necessary adaptation because the eye is "immune priviledged" and is cut off from regular immune responses to prevent inflamation from blinding you.

    I wouldn't be too concerned unless you have pain or start to have redness.

    The cold feeling could have been a result of air being pushed out of the dropper ahead of the fluid.
