Some people may be surprised that they may get free contact lenses. It is possible because there are so many contact lens manufacturers so that the competition is quite fierce. Contact lenses are the preferable choice for some people that they are not ready for laser eye surgery. And contact lenses offer a more natural appearance. In the United States, contact lenses require a valid prescription from an authentic eye doctor. Customers can go to any optical store or eye care practitioner to have an eye exam, after which a prescription is available. A prescription for contacts is quite different from a prescription for eyeglasses. These two kinds of prescriptions have different items, which is quite understandable that eyeglasses and contact lenses fit the eyes in different ways. Contact lens wearers should also know some pros and cons about lens wearing. Taking good care of contact lenses is very necessary, in order to prevent any eye infection or inflammation. Lens insertion and removal need some skills. For those with special eye conditions such as dry eye, re-wetting drops are needed during the day. Toric contact lenses are specially designed for people with astigmatism. These lenses are harder to fit and adapt to. Sometimes several sets of free trial lenses are needed. With these trial lenses the doctor can finally adjust them properly. Currently, many contact lens manufacturers offer free trial contacts, such as Acuvue, Durasoft, Air Optix, Focus Dalies, Purevision, Cooper Vision, O2 Optix, Johnson & Johnson and Bausch & Lomb and so forth. Customers should not wear these free contacts for a long time. After at most 30 days, they should be discarded. But free contact lenses from several brands can usually support a customer for a long time. Most manufacturers require customers to record something about their trial products. These elements include whether the contacts are comfortable, easy to insert and remove, dry eye problems and so on.
