If you are over the age of 40 and having some difficulty reading books and newspapers, you might have developed presbyopia, a common age-related condition that makes it challenging to focus on near objects. If you already struggle with distance vision, and are later on diagnosed with presbyopia, you don't need to carry a separate pair of reading glasses. Multifocal lenses help you have good vision all the time, tending to both issues at once.
At one point, bifocals were the popular fix, but they have a significant disadvantage; even though they correct problems with both near and distant objects, middle distance is blurred. To fix this problem, progressive lenses were developed. These offer a transition region allowing you focus on distances that are in the middle. Progressive lenses, which are also called no-line lenses, are a type of multifocal lens that have a subtly curved lens surface instead of an obvious and harsh line distinguishing the two parts of the lens.
These lenses, although better, can require a small period of time to get used to. Despite the fact that the gentle lens curve results in a product that is aesthetically pleasing, the lens's areas of focus are small, so that there's also room for transitional areas.
Bifocals aren't entirely dated though; they are helpful for children and teens who have a hard time focusing when reading.
When you go get fitted for multifocal lenses, make sure it's with an eye care professional you trust. Multifocal lenses are most beneficial when properly fitted to your eyes, needs and line of vision.
If your prescription or fit is off you may find yourself suffering from eye strain, discomfort and even migraines. During middle age, most of us cannot dodge presbyopia. But it's important to know that the right lenses can enrich your vision, and your life.
