Multifocal contacts are one of the greatest inventions that have come about over the years. Many people spent years wearing single vision contacts while carrying around reading glasses or straining to make out small print when they did need to read something. Others just continued wearing glasses to avoid this scenario. Yet with the progress that has been made in multifocal contacts this no longer has to be the case. You won't have to worry over reading glasses or miss out on important things. Anyone can now have the convenience of contacts.
Multifocal contacts include all contact lenses, including bifocal lenses, that contain more than one power. They work in one of two ways. Alternating vision lenses require your pupils to shift either up or down, depending on which distance you are trying to focus on. There is a visible line between two portions of the lens and your pupil will need to determine which is appropriate for what you are trying to view. Most of these lens are gas permeable. This means they do not move around on the surface of your eye. When you look down, the contact lens stays in place and you are able to view things through the lower portion of the lens.
Simultaneous vision lenses, on the other hand, have your eyes looking though near and distance powers at the same time. Your vision system, the wonderful machine that it is, can determine which power choice to use. Simultaneous lenses are available in two versions. The first is concentric ring bifocal contact lenses. Multiple rings are centered around the pupil of your eye. One ring is for distance vision while the other is for close-up work. If more than two rings are required, due to your prescription, the rings will alternate between the two visions. Based on your prescription, the location of the powers will differ.
Aspheric lenses, the second type of simultaneous vision lenses, are also known as progressive contacts. Here your eyes will work together will looking through the combined powers. Your eyes will adjust to the system and these are the most popular types of lenses available to day. Whichever way you decide to go will be based not only on your personal preference, but also on what your doctor determines will work best for your eyes. Pupil size is a factor as is your prescription for near work. This is no longer a problem as free trial lenses are available. Your doctor will work with you to find the perfect pair at the perfect fit.
