Hi. I'm online and happy to answer your question today.
By wearing contacts lenses at night you greatly increase your risk of getting a serious corneal ulcer or otherwise damaging your eye. This is especially true if the contact lenses are not specifically designed and marketed for extended/overnight or full-time wear.
The occasional discomfort you are feeling can be thought as a "wake up call" from your Guardian Angel that you are doing something that you shouldn't be doing.......
This discomfort is probably a sign that you might have a micro scratch on your cornea, swelling of your eye or some other "sub-critical" damage to your cornea that, if it was just a little bit worse, or if conditions were a little bit difference, could blossom into a vision threatening corneal ulcer.
So. What is the take home message? Don't do this :(
At least try not to make a habit out of it....
Is there anything else you would like to discuss at this point or have all your questions been answered to your satisfaction?

We have been experiencing problems with the chat system for the last few days. Our engineers are working on it. However, I'll switch over to the Q&A system. This system works a lot like 'text messaging' but an email is sent to each of us anytime something is posted to this thread. We can continue to work on your question there..... :)
