Extended wear contact lenses

I grew in the family where all my relatives were tender-eyed persons. Everybody cleaned permanently their distance spectacles with special alcohol wipes and put their glasses into their eyeglass cases. Nowadays contact lenses are widely available. Jill, one of my friends, uses online Medifast Coupons and orders contact lenses successfully. Most tender-eyed people believe that wearing contact lenses overnight is a great convenience. I find it sketchy wearing contact lenses overnight without cleaning and disinfecting them every day. May be risk is justified.
