Having to remove the lenses every night before going to sleep can get irksome, especially if you are tired and just want to drop dead on your bed. Probably it’s time to pay tribute to extended wear contact lenses. Extended Wear contact lenses are, like daily contact lenses, with the only difference being in their duration for which they can be worn at a stretch.
