Multifocal Glasses: A Breakdown of the Many Types
Right now, millions of people around the world are suffering from a vision-related condition that far too many of them don’t know enough about. It’s called Presbyopia and it refers to a specific type of farsightedness that happens when the lens of your eye loses its elasticity as you age. It’s fairly common in middle and old age in particular and while it is certainly a normal part of getting older, it’s also one problem that you do NOT have to take laying down.
The symptoms of Presbyopia typically begin to set in right around the time you hit age 40. If you’ve noticed that you have a harder time reading a book without getting a headache, or if you have to squint extra hard just to see the text messages on your phone, this is the most likely culprit that you’re probably dealing with.
When that day comes (and make no mistake, it will eventually come for us all), one of the major options you have available to you involves investing in a pair of multifocal readers. While these are not designed to replace prescription eyewear in any way, they can be a terrific “stop-gap” solution to restore your vision back to working order.
But even then, you’ll almost immediately notice that you have a wide range of options available to you depending on your own specific situation. Do you need progressive lenses or trifocal lenses? What’s the difference? At the same time, what are these varifocal lenses and adjustable glasses that you keep hearing so much about? Which multi-focus reading glasses work the best, and which are right for me?
These are the types of questions we’re going to help you answer. If you really want to make sure that you buy the right multifocal glasses when you need them the most, there are three major things you’ll need to keep in mind.
Progressive Reading Glasses: What You Need to Know
Also commonly referred to as varifocal reading glasses, these are a popular solution for many people as vision problems start to develop with age.
A pair of glasses with varifocal or progressive lenses will have two distinct portions of each lens, instead of one. You’re essentially dealing with two halves – the top one and the bottom one. Each has a different strength depending on what type of adjustment needs to be made to your vision to allow you to properly focus.
So if you were trying to see something that was physically close to you, you would look through the bottom. If you wanted to see something clearly that was far away, you would look through the top.
Adjusting where you look depending on what you want to see can be difficult for people to get used to, but many people enjoy progressive reading glasses without issue every day.
Examining Trifocal Reading Glasses
Trifocal reading glasses are a lot like progressive or “bifocal” lenses by design, but as the name suggests they add a third region to the makeup of the lens instead of the traditional two.
As was the case with progressive lenses, if you wanted to see something very close to your face you would look through the bottom. If you were trying to focus in on something far away, you would look through the top. But if you wanted to see something that was an intermediate distance away (think: arm’s length), you would stare straight up the middle.
Again, you have to adjust where you’re looking depending on exactly what you’re trying to focus on, but trifocal glasses too prove to be an effective solution for a wide range of different people.
Trifocal lenses tend to be used by people going through the advanced stages of Presbyopia because of the superior level of visibility that they offer.
The Power of Adjustable Focus Glasses
The third major type of multifocal glasses to consider take the form of adjustable focus lenses. Adlens’ own UZOOM glasses are just one of the options you have available to you in that regard.
By design, adjustable vision glasses are perfect for focusing in on things that are up to 6.5 feet away. One of the many reasons why these are so popular is because unlike other types of multifocal lenses, you don’t actually have to change your eye position depending on what it is you’re trying to look at.
If you want to focus better on the small print in the book you’re reading, you would just move the dial on the lens until the clarity returns to your vision. If you want to shift and look at something else, just adjust the dial again – the whole process takes only a few seconds.
The beauty is that the change occurs in the lens itself and because of this, it positively impacts your entire field of vision. Every time you adjust the dial, a series of two lenses actually change position until your focus returns to normal. It’s very straightforward and, for many people out there, a very effective solution to their problem.
Again, nobody is saying that any one particular type of multifocal readers is better and/or more effective than any other. They all have their own unique advantages and disadvantages and much of those are a matter of opinion, to begin with. But now that you know more about what each type is designed to do and how they work, you can make the most informed decision possible for your vision and your health in general.
