Bifocal, Trifocal, Multi-Focal… Various Types of Reading Glasses  

At some point, the following scenario happens to all of us:

You're laying on the couch on a lazy Saturday afternoon, reading your favorite magazine that just came in the mail and you suddenly stop yourself. You realize that at some point, you moved that magazine just a few short inches away from your face - you wouldn't have been able to see the small text on the page otherwise. At first, you think it's just that the room doesn't have enough light - but when you realize that all of the shades are up and every lamp in the house is on, you're hit with a striking and unfortunate realization.

It's not the magazine. It's not the light. It's not the room. It's your eyes. You need reading glasses.

It's something that will happen to all of us, whether we like it or not. But when you do a quick online search of reading glasses, you instantly realize that there are a huge variety of different types for you to choose from. Bifocals, trifocals, adjustable focus lenses and more. They all sound technical and, quite frankly, overwhelming.

Stop. Take a deep breath. The fact of the matter is that these are all unique options and each brings something different to the table... meaning that there is probably only one right solution for your current situation. If you really want to make sure you're buying the right type of reading glasses to help regain control over your vision, you just need to know as much about each one as possible.

The Different Types of Reading Glasses: Breaking Things Down

Progressive reading glasses, also commonly referred to as varifocal lenses, take the form of a few different popular types of reading glasses: those being bifocals, trifocals and others. What you're actually dealing with are lenses that are essentially split into a few distinct portions, each with their own region and focal length, for you to look through depending on what you're trying to accomplish in the moment.

With bifocal glasses, for example, the lens is essentially split in two. If you want to see something clearly that is far away from you, you would look through one part of the lens. If you wanted to see something that was close up to your face (like the text in a book), you would look through the other part of the lens.

Trifocals operate on the same basic principle, but with the addition of another section - one designed to help you clearly see things that are a medium distance away.

For a lot of people, these types of lenses are a great way to combat the effects of something like Presbyopia - but they do take a lot of getting used to. You essentially have to "train" your eye to look not just ahead of you, but through a different part of the lens depending on whatever it is you want to focus on. If you want to split your attention between two objects - one that is close up and another that is far away - you'll be dealing with a lot of somewhat unnatural movement in your eyes. Having said that, a lot of people use these types of progressive lenses without any issue and it's a solution that is at least worth exploring when the time for reading glasses finally comes.

Adjustable lens glasses, on the other hand, are something entirely different. They still allow you to change the focal length of your glasses depending on what you're looking at, but instead of using a single lens split into multiple parts they use multiple lenses that you can adjust the position of to achieve a very similar affect.

If you were trying to read a book, you would just reach up and move the dial on the side of the lens until your vision returned to focus. If you then wanted to watch TV, you would just adjust the lens again and in a few seconds you'll be ready to go. The major benefit of this is that it impacts your entire field of vision, not just whatever it is that you're specifically looking at. Perhaps the only major downside of these types of lenses is that they're not really good for things that are very far away from you - objects within six or so feet from your eyes are really in that "sweet spot." They're also not intended to replace any type of prescription glasses that you may already be wearing.

Even still, they're very easy to use and they totally eliminate the need to carry multiple pairs of reading glasses around with you everywhere you go. Likewise, a lot of people enjoy the fact that you don't have to change the position of your eye to take advantage of the glasses themselves - you can just continue to live your life, the same way you always have, free from compromise.

The key thing to understand is that there isn't necessarily a "one size fits all" right answer to which of the types of reading glasses is the "best" - there is only the one option that is the best for your particular situation. As always, you need to think about your own lifestyle and preferences before you make a decision to go with any one particular type over another.
