Are Korean Color Contacts Safe?
There is a lot of speculation online saying that color contacts are dangerous, and Korean color contacts are unsafe, and that they can cause blindness. But are color contacts really unsafe? Let’s explain this in detail.
Color contacts are categorized by color, size, and the country of manufacture, such as Japanese or Korean products, etc.
It is dangerous to classify all Korean-made contacts as unsafe and all Japanese-made contacts as safe.
Currently, over
80% of the color contact lenses shipped to Asian countries are made in Korea.
Other imported color contacts include one-day lenses from the U.S. or Europe, and low-cost lenses made in China.
If you think that color contacts made in Japan are safe, check the manufacturing country of the contact container.
Most of them will be labeled "Made in Korea".
In Japan, there are hardly any color contact manufacturing factories.
This is not because Japan’s manufacturing technology is inferior, but because Japan has high labor costs, and Korea offers highly skilled labor at a relatively lower cost.
Most of the color contacts sold in Japan are OEM manufactured by Korean contact lens companies.
Also, some people inquire about finding insects on contacts.
This should never happen. If you look at the manufacturing process, you will see that high-temperature sterilization is performed at least three times, and automatic secondary packaging is done in a dust-free, clean environment.
The package's interior is soft to protect it from scratches and damage.
In a completely sealed state, oxygen cannot enter, and not even a drop of water will leak out.
The completed products are placed in specially sealed bottles or sealed packs to ensure they are fully sealed during manufacturing.

There are pictures circulating online showing color contacts with insects, but this should never happen with unopened products.
If you see such pictures, they are most likely of opened products.
All Korlens products are fully sealed before shipment, as shown in the photos above.
At Korlens, we only carry color contacts that have passed safety inspections and have international certification marks.
Customers who purchase products can check for FDA, GMP, CE, or ISO international certification marks.
Why has the idea that color contacts are dangerous spread?
Color contacts are tinted with colors like brown or blue, and there was a time when people feared the pigments would dissolve and harm the eyes. This became a hot topic for a while.
So, do pigment dissolving incidents still happen frequently? Almost never.
Some may still be doubtful, so let's dig a little deeper into this topic.
Are Korean Color Contacts Safe?
With technological advances, dangers have been eliminated!
Not only in the field of color contacts, but new technologies are being developed daily that solve problems that were once a concern.
The issue of pigments dissolving and potentially harming the eyes was a problem of the past, and we now live in an era where color contacts can be safely manufactured.
There are actually various methods for manufacturing color contacts, and the main four methods are as follows.
Cast Mold Method
This method involves placing the contact lens material and dye into a machine, applying pressure, and shaping the lens.
Semi-Cast Mold Method
This method involves coloring the outer side of the lens with dye and then covering it with a special polymer.
Spin Cast Method
This method involves flowing liquid soft material into a rotating dish and forming the lens using centrifugal force.
Sandwich Method
Coloring the part of the lens that touches the iris, then covering it with another layer of lens material, trapping the color in between to ensure safety.
Even though it might be difficult to explain in words, the safest method is the sandwich method, followed by the semi-cast mold method.
The cast mold and spin cast methods are generally safe, but in rare cases, a defective product may cause the dye to leak, which could come into direct contact with the eye and potentially cause irritation.
At Korlens, we only handle Korean color contacts made with the safest sandwich method.
All of Korlens' color contacts are loved by both Korean women and many customers in Japan, so you can be assured of their quality.
