Always put in your lenses before applying makeup to keep makeup particles off your lenses and lessen your risk of eye infection.
Always wash, rinse and dry your hands thoroughly before touching your contacts, so you won't transfer any oils, creams or lotions to your lenses.
Use cream eye shadow vs. powder. Powder particles can get in your eyes and cause irritation.
Never apply eyeliner between your lashes and your eye. You can accidentally poke, scratch or harm your eye in the process.
Take your contact lenses out before you remove your makeup. If you leave your lenses in, you could accidentally wipe makeup onto your lenses.
