Kate had something a while back that was just labeled "conjuctivitis, unspecified". Eye Doc told her to stop using eye make up until it was gone, buy all new eye make up, and scrub her eyes, esp. lashes with No Tears Baby Shampoo every day, plus the drops.
A new mascara should be purchased every 3 mos. Mascara is moist so it is a great breeding ground for the Nasty Guys. Any make up used just before the infection/virus should be tossed, esp. eye pencils, liners and shadows. We smear them across our eyes, then dab back into the make up.
