Trifocal Lenses Advantages & Disadvantages:
Detailed Information
As you get older, your eyesight worsens, and there is no guarantee that
you can keep your eyes at a 20/20 vision until you get old.
But that does not mean it is impossible to have a clear vision; it’s just a
bit hard to keep your eyes healthy, especially if you are a workaholic
person who doesn’t have too much time.
Luckily, trifocal lenses have been made to benefit people with eye
prescriptions, especially those who have an eye condition called
presbyopia.
If you have multiple prescriptions, your optometrist may prescribe you
the trifocal lenses.
However, are these lenses perfect for the eyes? What are the things you
need to know before wearing them?
Let’s find out!
Trifocal Lenses: What About It?
Before understanding the features of trifocal lenses, let’s learn a little
more about them and how exactly they work.
As the name suggests, Trifocal lenses have three regions for different
visual pictures a wearer can see.
These regions have three focuses that correct for distance, intermediate,
and near vision; they offer correction for people’s near and far-distance
vision and enable users to see an intermediate view level.
These lenses were invented for people who lack an intermediate view of
what they can see, especially those who have presbyopia.
What Is Presbyopia?
Presbyopia is an age-related eye condition that adults usually
experience where their vision becomes hazy and compromised.
This is a disorder where the person is affected during the aging process;
it’s the eye’s progressive loss of its ability to focus on nearby objects.
While some people fail to recognize this problem, many people
consciously do realize the issue, and therefore it’s always recommended
to timely visit your optometrist and get your eyes properly checked.
Advantages & Disadvantages Of Trifocal
Lenses
Trifocal lenses are beneficial to adults in aiding them with their vision, so
it’s essential to know how these lenses affect their lives.
Unfortunately, everything comes with its good and bad; similarly, trifocal
lenses have their advantages and disadvantages, as discussed below:
Advantages
● Since these lenses are trifocal, it lets users view clearly from
every angle they look, at without feeling the need to squint to
see things.
● As mentioned earlier, adults with presbyopia are more
suitable for trifocal lenses. This condition is a natural part of
aging, where adults tend to get headaches while focusing to
see their surroundings especially when their vision is not at its
best. This makes the intermediate region of the lens effective
for their field of view.
● Users can obtain a broader view of near and intermediate
vision levels in the lens, which means your eyes do not need
to adjust that much to see a specific part of the lens.
Disadvantages
● Irrespective of whether you are using glass or plastic lenses,
wearing trifocal lenses can take some time for you to adapt.
● Please note that there are three regions in this lens, and your
eyes have to remember every part of your glasses to prevent
your eyes and head from hurting every time you look at a
particular region.
● If you look at the wrong part of the lens, you can see some
distortions on the object or surface you are trying to check. If
this continually happens, it may worsen your vision because
your eyes cannot comprehend the region you are always
looking at.
● Sometimes, the close-up region of the trifocal lenses is not
sufficient for prolonged use, especially your peripheral vision,
which is tempting to look at the other areas even when you
only need to use the near vision.
● You cannot customize the division of each region; you may
want to consider bifocal or progressive lenses if you can’t
handle the trifocal lenses.
Are Trifocal Lenses Worth It?
Trifocal lenses give you an improved vision of all angles, but that does
not mean you must necessarily wear them.
Trifocal lenses are worth it only if you can take risks when you already
have the glasses in your hand.
You may benefit from wearing them, but we cannot avoid the
disadvantages that come with them.
Nevertheless, they are suitable for adults willing to help their eyes adjust
to a new type of lens and those who have presbyopia.
If you are a person who quickly gets annoyed at minor inconveniences,
take time to reconsider having trifocal glasses.
They might require some time to get used to because you always have
to remind yourself that your glasses have three different regions for three
different optical levels.
Sometimes, it can cause anxiety, and it can frustrate you even more.
Are Trifocal Lenses Expensive?
Trifocal lenses’ job is tougher than that of normal lenses or even bifocal
ones.
Unlike bifocal lenses, trifocal lenses correct three types of vision
simultaneously, close-up, intermediate, and far-away. Hence due to this
feature, trifocal lenses usually have a high cost.
Trifocal lenses also have their own varieties. Progressive lenses are one
of them. While trifocal lenses have three distinct prescriptions on lenses
indicated by lines, progressive lenses blend these prescriptions and
have no lines on the lenses.
Since progressive lenses don’t create any image jump while looking
through them, trifocal lenses cost more than normal trifocal lenses.
If customized features are added to the lens, it just adds to the base
cost.
For example, trifocal lenses with distinct lines cost the least and are
usually inexpensive, but if you go for progressive lenses the cost
increases.
Specific custom features like thin lenses, adding protective layers, or
specific materials increase the cost even more.
What To Consider Before Purchasing
Trifocal Lenses
If you are considering trifocal lenses for your everyday use, you must
consult your optometrist.
You cannot just decide on your own because you are convinced with
what you know about the lenses; a professional should give you advice
since everyone has different eye problems.
You should ask and discuss with your eye doctor the advantages and
disadvantages of these lenses because you need to prepare yourself for
what is about to come when you already have them.
They may tell you whether you should use them or not, and whatever
that is, listen to your optometrist’s advice.
Also, if you are going for daily use, a plastic frame would be a wiser
choice as compared to a heavy metal one.
Final Words
Trifocal lenses can help you view clearly in close-up vision,
intermediate-level, and faraway objects.
Not only can they help your eyes look clear, but trifocal lenses can also
lessen your stress about your vision – only if you are going to have them
as your primary lenses for your eyeglasses.
However, not everyone is the same, so using them largely depends on
your requirement and comfort and whether you can wear them regularly.
Always consult your optometrist when it comes to eyes because you
cannot just decide by yourself on how to improve your vision.
Avoid self-medication and make proper use of your knowledge along
with your eye doctor’s help to get the best solution for your eye
problems.
