Everybody today likes to be aggressive — have you ever heard of progressive contact lenses? These are specially designed contacts, manufactured so that the surface of the lens is divided into different "regions". The top part of a progressive contact lens is designed to help you to see over distances; in the bottom half is designed to help you to see things that are near to you. If you look through your progressive contact lens using the middle section, this will help you to view items that are in the mid-range of your field of vision. As you can see, progressive contacts are very sophisticated in their design.
