Wearing glasses can be a real day-to-day hassle, not to mention using contact lenses which have to be
cleaned, rinsed and disinfected every so often. Fortunately, however, for those millions of contact lens
users, there's a new product out -- the 1–day Acuvue.
    These new disposable contact lenses are designed to be convenient and rather inexpensive because the
idea is to throw them away after use at the end of each day. What's even better is if you are planning to
give them a try for the first time, the manufacturers will give you your first five pairs for free. If you
don't think that's possible, why not go down to your local optician and check it out? No one will blame you
for doing that. After all, seeing is believing.
