How do you wear soft contact lenses while on a camping trip of 7-10 days?

It depends which type of soft lenses you have. If they are extended wear lenses, then you can keep them in while you sleep, just remember to put 1-2 drops of rewetting/lubricating solution in each eye when you first open your eyes in the morning. The safer thing to do is take them out at night when you can to allow your eyes to breathe. You can leave them in (if you have extended wear), but I would only do so for 5 days straight and then take the out for a night.
