Latisse can be used safely in contact lens wearers. Typically the Latisse would be applied at night just after removing your contacts. A very small amount of Latisse should be very effective so apply lightly.
Latisse is safe to use for contact users. Be sure to remove contacts before applying Latisse in the nights.
Latisse should be applied to the upper eyelids only - and usually it's preferred to do this at night. That way, when you close your eyes to sleep, the lids will touch and transfer the solution to the lower lids as well. Take your contacts out before applying the Latisse, and everything should be just fine. There are many, many, many people who successfully use Latisse and wear contacts.
