Is there any particular risk for adverse reactions from people who wear contact lenses?
Vaccinia infection of the eye is a potentially serious complication of vaccination and can lead to altered vision. Therefore, all vaccinees need to be very careful to not inoculate the vaccinia into the eye. You should do several things to ensure you do not inoculate virus into your eye. Covering the vaccine site with gauze, tape, and a sleeved shirt or similar clothing, and careful handwashing decreases the chance of inadvertently getting vaccinia virus on your hands and possibly into your eye.
