The next option made available is that type iGenics of corrective technology that the contact lenses will use. The three most common options are concentric bifocals, alternating image design, and simultaneous image design. Concentric bifocals are fairly simple. The center portion helps you see close up and the outer portion helps you see things that are far away. Alternating image design (translating design) are only available in GP lenses and have the distance portion of lens on top and the close-up portion on the bottom (just like traditional bifocals). The final option is simultaneous image design. These lenses can be either soft or GP. They place both the near and far powers across the center of the lens so that you are can focus on both simultaneously.While these options may seem a little overwhelming at first, your optometrist should be able to let you know which ones will be viable for your specific needs. From there it is simply a matter of trial and error until you find the one that feels the best, while also correcting your vision. While there are a number of additional details to keep in mind when looking for the right type of multifocal contact lenses to meet your needs, this quick introduction should help you get started in the right direction.If you are dealing with an astigmatism then your optometrist will likely suggest some type of special contact lenses: toric contact lenses or GP (Gas Permeable) lenses.

To give you a better idea about which ones will be right for you, here is a closer look at what people dislike about each option.
