Which one do you recommend? How to choose glasses and contact lenses
Many people may wonder if they would opt for glasses or contact lenses when
they need to correct their eyesight.
When choosing eyeglasses and contact lenses, it is important to choose
according to the condition of your eyes, Also, you want to choose the one that
suits you best. So, this time, I will explain in an easy to understand way how
to choose glasses and contact lenses.
A mechanism seeing things
The human eye has a structure similar to a camera. Light is captured from the
cornea, which acts as a camera lens, and the crystalline lens behind it
adjusts focus. Then it moves to the retina, which acts as a film for the
camera, and you can see things.
Reasons why things are hard to see
There are individual differences in seeing things. Even if you say your
eyesight is poor, there are different types of conditions such as
nearsightedness, farsightedness, and astigmatism, each with different
characteristics. I will give in detail what kind of features it has.
Nearsightedness
It is difficult to see things from a distance. The face of the distant person
may be blurred and identification may be difficult, or the letters on the
board may be blurry and difficult to read.
Farsightedness
Since it is necessary to adjust the focus regardless of the object's distance,
it is easy to get tired. Since there is no glitch in the focus adjustment
function, there is a problem that is hard to notice just by looking at it. If
you leave it unintentionally, you will feel tired in your eyes and it will
affect your daily life.
Astigmatism
The disadvantage is that the subject is out of focus, the object appears
double, and the outline becomes blurred. The lowercase letters appear double
and are difficult to read, which interferes with everyday life.
As mentioned earlier, there are different types, so it is important that an
ophthalmologist check the condition of the eye first. If you leave your
eyesight weak, your eyesight may be damaged even more. Headaches may come from
tired eyes, so see your eye doctor early.
Should I choose glasses or contact lenses?
Both glasses and contact lenses can correct your eyesight, so we recommend
choosing based on your characteristics and preferences. As we'll introduce
next, choose what works for you, including your lifestyle and way of thinking.
Glasses are easy to clean
No special care is required for glasses. Care can be completed simply by
gently wiping away dirt with a special eyeglass squeegee. Contact lenses
should be rubbed with a special cleaning solution and stored properly. One-day
contact lenses can be discarded, but lenses longer than two weeks should be
stored. The glasses are suitable for night trips.
Contact lenses suitable for sports
Because contact lenses stick to your eyes, they are difficult to remove even
with strenuous exercise. Glasses can be damaged by hitting your hands or
balls. In addition, the frame narrows the field of view and the glasses are
easily slipped, making them unsuitable for exercise.
Glasses are less affected from the lenses
Contact lenses have a base at the time of wearing. Using contact lenses for a
longer period of time will increase the pressure on the eyes and increase the
risk of eye disease. Since there is no time limit for wearing glasses, they
are suitable for people who spend the night. However, you must be careful
because the night owl itself puts a strain on your eyes.
Contact lenses if you don't want to change your impression
Wearing glasses will change the atmosphere of your entire body as well as your
face. Unless you want to incorporate glasses into fashion, contact lenses are
recommended if you do not want to alter your impression. You can correct your
eyesight without changing your impression.
How to choose the glasses that suit you
Wearing glasses that don't fit can make you feel tired and uncomfortable. It
is important to consider the following points and choose the glasses that are
right for you.
- It doesn't hurt anywhere
If you feel discomfort or pain in your ears or nose when wearing glasses, this
is not for you. Let's make her adjust at the glasses store. If you don't feel
uncomfortable calling, you can say it works for you.
- Is the frame type identical?
There are different types of tires such as plastic and gold rims. Weight and
comfort vary, so check the details. There are tires that can meet different
needs, such as tires that do not use metal or screws to reduce weight.
- Is the frequency etc correct?
Check if it suits you, such as pace and presence or absence of astigmatism.
The use of ill-fitting glasses can cause eye strain. It is necessary to make
adjustments according to the scene of use, such as whether you will use it
throughout the day, while driving, or only during class.
How to choose the contact lens that suits you
After practicing wearing contact lenses, some people may find that they are
not good at wearing contact lenses and that they are not suitable for them.
But at first, everyone has difficulty wearing contact lenses. By practicing
without rushing, you will gradually get used to wearing it.
Choosing the right contact lens for you is the first step towards
comfortable use. There are different types of contact lenses that differ in
terms of continuous use and materials. Check out the following items and
choose the one that suits you the most.
- oxygen permeability
Since your eyes also breathe, it is important to choose contact lenses that
can supply oxygen. The amount of oxygen passed depends on the contact lens,
so consult an ophthalmologist to select one.
- Continuous use period
One-day contact lenses, which can be discarded in one day, do not need care
with cleaning solutions. Contact lenses that are 2 weeks and 1 month old
should be cared for and stored by rubbing with a special cleaning solution.
As you can see, the management is annoying, but the price can be kept less
than a day.
- Hard type and soft type
Soft contact lenses are difficult to remove even with strenuous exercise. In
addition, there is less amount of foreign matter and a natural fit can be
obtained. Rigid contact lenses have the feeling of a foreign body until you
get used to them, but they have high visual acuity and correct astigmatism,
and they have the advantage of allowing oxygen to pass through firmly.
