plastic vs. polycarbonate vs. glass lenses - their pros and cons  -  polycarbonate
Nowadays, different materials are used in lens manufacturing.
For a while, you can only make lenses with crown glasses.
Then, advances in manufacturing and laboratory processing techniques have led to the use of more materials such as plastic and polycarbonate.
There is an objection to the use of scratch-proof coatings in lenses.
They say it is a waste of money and time.
However, experts say that each lens requires a scratch-proof coating as it helps to properly clean the lens and extend the service life of the lens.
It's no wonder that today's lens makers brainwash, encourage them to buy plastic lenses and then tell them to charge extra.
As a matter of fact, nowadays, as polycarbonate lenses become more and more famous, you can hardly find anyone who uses plastic lenses.
It is said that the weight of the polyester lenses is lighter, thinner and impact resistant, which is true, but they are also more expensive than the ordinary plastic lenses.
So, at least for those with a limited budget, the polycarbonate lenses don't actually work for everyone.
So, it's better to discuss the pros and cons of these three materials.
After the glass lenses, the plastic lenses were welcomed by everyone because of the much lighter weight, but it was soon discovered that they were easily scratched.
The glass lens is a bit hard but much heavier than the plastic lens.
People's mentality is to hope that their glasses are light weight, no.
Invade as much as possible, which is why now the resin lens isthing!
So, as we discussed, the weight of the glass lens is greater.
Also, if you drop your glasses, they will have a high chance of being broken because the glass is easily broken when it falls.
However, it gives you the best optics, in other words, the best vision.
In addition, glass lenses do not scratch as easily as plastic or polycarbonate.
Plastic Lenses are lighter in weight and more anti-breaking, but they can easily scratch if you don't clean them properly.
They also do not provide your visual accuracy.
However, plastic lenses are a better option for most people because they don't want to carry glass lenses with extra weight.
Proper cleaning of scratch-resistant coatings and plastic lenses will allow them to last for a long time.
The resin lens is thinner, lighter and anti-crushing.
You can try hitting a polycarbonate lens with a hammer and find it doesn't break, which is a simple experiment.
Therefore, they are the safest lenses on Earth and have a high level of impact resistance.
But once you hit it with a hammer, your vision becomes blurred as the polycarbonate lens is filled with scratches and damage.
The polyester lens is very soft and flexible, but it is also easy to scratch, so you must use the appropriate cleaning method to keep the polyester lens running smoothly.
If not cleaned properly, your lens will only last about 10 minutes!
Some people complain about the inherent distortion.
There are also objections to color difference.
So even though they are the safest, you have to sacrifice some visual insight with a polyester lens.
Those who focus on prescription safety glasses and those who work in a safe environment must sit down with the safety director to discuss which lenses the customer should use.
You may think that you have to use polycarbonate lenses for the sake of safety as they are the most impact resistant and therefore the safest.
While this is true in some cases, what if the worker is in a very dirty or greasy dirty working environment?
During the manufacturing process of the polyester lens, no scratches should appear on the glasses.
Hands are dirty and workers who do not comply with the regulations will not be able to see through the lens because the lens is full of scratches.
So is it a good choice to use polycarbonate lenses?
Of course, your answer is No.
It's really better to have scratches on glass lenses.
It's easier for them to stay clean so they can see something better, which makes them safer.
All in all, you should ask yourself what is important to you.
Which material is the safest to use in glasses?
How will you keep them clean and the type of environment you will use these glasses?
Will you take care of your glasses?
You know, you're not very good at cleaning the lens properly.
Is your lens impact-proof and safe when used indoors and outdoors?
Are you looking for the best sight shot?
If you attach great importance to clear vision, are you willing to suffer extra pain when wearing heavy glass lenses?
So, even though for some people the optometrists brainwash them, they say wearing plastic or polyester lenses is the best for some, and it would be better to wear glass lenses.
It is true that glass lenses are not suitable for everyone, especially for children, because they have a tendency to quickly break the glass lenses and not take care of them as adults do.
Plastic or polyester lenses are a better choice for children.
You should sit face to face. to-
Before ordering the lens, face it with the optometrist.
You have to make yourself aware of the different options for glasses, and then you should choose the best for long-term use and durability.
