For all of those wearing contacts... let me give you a piece of well meant warning...
Yes, there are contacts out there you can wear for a month....
And yes, you can wear them longer.... BUTTT, you take a huge risk. If you get an infection because of wearing them too long, it is possible you will never be able to wear contact lenses again.
I am not in the business anymore, but used to be a troubleshooter for B&L Contacts lenses, and one of the top 10 in Belgium for contacts...
So, my advice, do follow the prescriptions... you might regret it otherwise...
