Everyone that uses contacts knows how easy it is to go over the recommended time of wear for each pair of contacts. I think this is more of a problem for those that have bi-weekly or monthly ones rather then the ones that wear daily ones. Before using RTM i would just try and "guess" when it was time to get change my pair. But now with RTM, it's pretty simple: just set a repeating reminder for yourself for every two weeks or every month (depending on the contacts you use) and have it remind you right in the morning when you wake up.

Another way RTM could help with contacts is to actually remind you to take them off before going to sleep! I can't begin to tell you how annoying it is to wake up in the middle of the night and realize that your contacts are still on. I usually forget to take them off when I am out of the ordinary routine (when I am travelling, or on vacation or camping). So whenever I am doing something out of the routine I set-up a reminder to be sent right before going to sleep to save me from not removing my contacts before heading to sleep.

Simple but effective I think. Hope it helps someone :)
