Are you over 40 and struggling to read small print? You might have developed presbyopia, a common condition affecting those reaching their 40s. If you’re already a glasses wearer, and develop presbyopia, you won’t need to start carrying and switching between two pairs of glasses. Multifocal lenses will allow you to see clearly all the time, tending to both issues at once.
In the past, bifocals were the popular fix, but they were far from all that great; while they correct problems with both near and distant objects, middle distance is blurred. In an effort to create something more helpful, progressive lenses were invented. These give you a transition part of the lens 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 featuring a gradual curvature across the lens surface instead of a noticeable line separating both parts of the lens.
But, you may require some time to get used to no-line lenses. While the subtle transition of progressive lenses is more aesthetically pleasing, the focal areas are quite small because more lens space is used for the transitional areas.
Bifocals are still used though; they are used to treat kids and teenagers who suffer from eye strain, stemming from a difficulty focusing while reading.
When being fitted for multifocal lenses, check that it’s with an eye care professional you trust. Multifocal lenses work best when properly fitted to your eyes, needs and line of vision.
If you’ve been fitted with the wrong prescription you could end up suffering from headaches, eye strain or even nausea. Presbyopia affects the majority of us at a certain age, but there are ways to make it less restricting. A good pair of multifocals will make a world of difference.
