Maybe: Depending of your age, symptoms and other medical conditions you have, you might want to check it out. Although this may be embarrassing, it would be worth it to establish a relationship with a primary care doctor to talk about it. It may be an example of food intolerance/allergy...Or in some cases more serious problems. Even if it isn't anything serious, they may be able to help you manage it.

It varies..: Varied answers from various eye care specialists. Generally I have a new rigid gas permeable (rgp) contact lens wearer, who is just commencing their use, to wear it for 4 hours the first day and then go up by one hour daily from that point on to a maximum of 12 hours. You want to avoid contact lens overwear syndrome where the eyes feel so comfortable with the rgps on that you do not break them in.
