Free Trial Day And Night Contact Lenses

There are a few steps that usually follow the procedure. First is an hour long medical test, a few things are taken into consideration as to your reason for switching from glasses to contact lenses, and the second being whether you can afford contact lenses or not. After this an exam known as refractomery is taken and then after a few medical procedures, the important step is the testing of the contact lens which is necessary to determine the curvature and diameter of the contact lens. The last and final step is the periodical exam depending on the type of contact lens you choose to wear. Among the most popular lenses are the Acuvue contact lenses, they are for people who have little or no astigmatism, also they are to be disposed every two weeks. Some Acuvue lenses are not only approved for everyday use but overnight wear too. They allow oxygen in even greater amount than the other types of lenses.
