What is the easiest and most harmless way to put on contacts?

Follow instructions. The best technique is to follow the exact instructions explained to you by your eye doctor when he or she demonstrated to you how to insert and remove them at the time of your acquiring them. Even with that, some people just have a harder time than others, especially if they have long eyelashes. I am an ophthalmologist and i wear contact lenses at times. I am not very good at putting them on.
