Walk into a drugstore in Japan, and you may be surprised by how many different eye drops are on the shelves.
There are products for tired eyes, dryness, itchiness, contact lens users, and even very strong cooling sensations.
But cooling eye drops are not unique to Japan.
Brands such as Rohto also sell cooling eye drops in the United States.
So what makes Japanese eye drops feel different?
Why Are There So Many Eye Drops in Japan?
One reason is that Japanese eye drops are divided into many different uses, such as tired eyes, dryness, allergies, redness, and contact lens discomfort.
In Japan, the feeling of the eye drops can also be part of the choice. Some products even show different cooling levels.
As contact lenses became more common, companies also developed more specialized products for different users.
So Japanese drugstores often offer eye drops based on both what you need them for and how you want them to feel.
Cooling Eye Drops Exist Overseas Too
Cooling eye drops are available outside Japan.
So it would not be accurate to say that only Japanese eye drops have that refreshing, cooling feeling.
What stands out in Japan is the large variety of choices.
So Many Choices for Different Needs
Japanese drugstores often have eye drops for:
- tired eyes
- dry eyes
- itchy eyes
- allergy symptoms
- contact lens users
- cooling and refreshing sensations
Some products even show a cooling level.
For example, some Sante FX products indicate how strong the refreshing sensation is.
So you are not only choosing what the eye drops are for.
You can also choose how cool you want them to feel.
That makes browsing the eye drop section surprisingly interesting.
Small, Affordable, and Easy to Take Home
Many Japanese eye drops are small, lightweight, and relatively inexpensive.
Some products cost only a few hundred yen, so they are easy to pick up during a visit to a Japanese drugstore.
They also take up very little space in your luggage.
For travelers looking for a small and practical item from Japan, eye drops can be an interesting souvenir idea.
However, eye drops are medicines, so check the ingredients, directions, and import rules of your destination country before giving them as a gift.
Contact Lens Users Should Check the Label
Not every eye drop can be used while wearing contact lenses.
Even products from the same brand may have different instructions.
Some can be used with soft contact lenses, while others require you to remove your lenses first.
Similar packaging does not always mean similar usage, so always check the label before buying.
Quick Summary
Cooling eye drops also exist overseas.
What makes Japan interesting is the amount of choice.
You can find products for different eye conditions, different types of contact lenses, and even different levels of cooling sensation.
They are also often small and affordable.
So Japanese eye drops are not necessarily unique because they only exist in Japan.
What is unusual is how much choice you get from just one drugstore shelf.
