Presbyopia or aging eyes is a condition that affects almost everyone over the age of 40. It becomes extremely difficult to focus on the things when this condition develops. The natural lens of the eye gets to be distinctly impervious to changing its shape the way it does when we are more youthful. In addition to it, the eye muscles responsible for controlling the shape of the eyes also become weaker with the time. Until recently, the only option was to wear eyeglasses with bifocal lenses. With the availability of Multifocal lens, now it is possible to treat this condition effectively.
The reason behind the increasing popularity of Multifocal lenses is they are customized according to the eyesight needs of an individual to make sure that you actually get what you need to see the objects clearly. Since Multifocal lenses are available in different designs, it is essentially important to understand that which design will work best for you. Here we will discuss the three major types of Multifocal contact lenses:
Concentric Bifocal Design- This is the most common type and is preferred by many people. It has two different prescriptions where a small circle is surrounded by a much larger circle that helps with correcting your near vision and distance vision respectively.
Alternative Image Design- This type of design is primarily used for reading and driving, but is not appropriate for mid range tasks such as watching television or working on a computer. They are somewhat like bifocal glasses lens. For a distance view you are required to see through the top of the lens and for the nearer view you must see through the bottom part.
Simultaneous Image Design- This design has shown promising results in the last few years. Here, both the near and distance prescriptions are put on top of each other. It is then up to your mind to choose which part of the lens to focus on and which part to neglect. The advantage of this design over concentric and alternative design is that it allows the wearer to view the objects clearly in a wider area.
