Along with graying hair, wrinkles, and other tell-tale signs that we are getting older is a condition of the eyes called, Presbyopia. Presbyopia is from the Greek word, “presbys” which means, “old man, or “elder” in conjunction with the Latin term “-opia,” which means, “eye.” It burdens us with less ability to see things close up.

The signs of Presbyopia can be first noticed around 40 years of age. In low light, reading small print begins to become more difficult. Also, eyestrain becomes a problem after reading for long periods of time. When reading, it becomes more and more necessary for the sufferer to have their reading material further and further away in order to focus. This symptom is even more prevalent, in lower light conditions. But, conversely, it becomes less of a problem in brighter light conditions. That is because, like a camera’s lens, the lens of the eye or “iris,” closes down to a smaller diameter to let in less light. In doing so, the focal ratio increases the variant in distance, so that the depth of field is greater. It means that we can see more normally; seeing less objects out of focus.

Since Presbyopia is a naturally occurring symptom of old age, it is basically incurable; just like graying hair or wrinkles. But, just as we can touch up and color gray hair, or put creams and ointments on our skin to diminish wrinkles, we can reduce the symptoms of Presbyopia with reading glasses or contact lenses.

In the case of contact lens, there are at least two methods that people use to help them with reduce the symptoms of Presbyopia. One is the “monovision” method. In this process, a person would choose to wear two different prescriptions of contact lens; one to correct an eye for seeing objects that are near, and one for seeing objects that are far away. But, this method of correction is based on older technology. Science has now provided us with multifocal contact lenses; allowing us to see better in varying situations of light and distance.

Multifocal contact lenses are an excellent choice for correcting Presbyopia in that they eliminate the need for glasses, while providing good far and near distance vision. Some multifocal contact lenses work with a bifocal design with two different lens powers built in; one for distance and the other for close up. The other common design is “progressive” in that there is a gradual change in the power of the lens so that a person has more of a natural experience of transitioning between close-up and far distances.

Multifocal contact lenses also come in a soft, or a rigid style; for daily wear or extended wear. Wearing contact lenses overnight or for extended periods of time would require the extended or rigid style, while the occasional use of contact lenses would allow you to choose the soft multifocal contact lenses style.
