Why contact lenses get blurry and dry towards the end of the day?

[Weidman]

I wear my contacts to school everyday and sometimes on the weekend for about 2 years now and have never had any problems. But lately I have been noticing that towards the end of the day my contact lenses get extremely dry and blurry. I now have to carry a small solution bottle wherever I go in case this develops. Any suggestions?

Generally it is better to wear contact lenses no more than 8 hours per day. Wearing them too long will make your eyes lack of oxgen and cause blurring . Dryness is a sign that you need to take them out.
