Cheap Contact Lenses Online
All you need is a valid contact lens prescription. However, if your prescription has expired or if you feel that your vision has changed since the last prescription was written, you will need to make an appointment with your eye doctor.
Unless your eye care practitioner has fit you into FDA-approved overnight-wear contact lenses, you should NOT sleep in your lenses. It is healthier to remove your contacts at night and put them on again in the morning after you wake up. Many studies have shown that the incidence of infections and red eyes are increased for patients who sleep in their contacts.
