"On October 10, 2006, WebMD reported that statistical analysis revealed that contact lens wear infection risk is greater than the infection risk from LASIK.[53] Daily contact lens wearers have a 1-in-100 chance of developing a serious, contact lens-related eye infection in 30 years of use, and a 1-in-2,000 chance of suffering significant vision loss as a result of infection."

so don't worry, its normal. Happens to me sometimes too. Just make sure you are not sleepin with your contacts on, or taking a shower with them. Even though i take a shower with my contacts on, becuase its a pain to take them off and wear them again, it really recommended not to. Water contacts bacteria and if that bacteria goes in your lenses through your eyes, then you have a good chance of getting an eye infection

 

I wear my contacts for 2-3 weeks... straight. I don't take them out at night.

Have been doing this for like 5 years now. Have never had a problem. When the contacts bother me I pull them out and pop new ones in.

 

i'm on week 5 with these! woot! lol. 3 more days till week 6
