[New Release] Dujup Launches Polarized Sunglasses Designed for Asian Facial Structures. Price Reduced from ¥10,999 to ¥2,999 During Amazon Prime Day.

Eyewear brand "Dujup" has launched a new series of sunglasses with an Asian fit design, taking into account Japanese facial structures.

This new product line features "polarized sunglasses" that reduce reflected light and glare for clear vision, and "photochromic polarized sunglasses" that combine photochromic performance, where lens darkness changes according to environmental factors like UV rays, with polarization capabilities.

During Amazon Prime Day, from July 7, 2026 (Tue) to July 13, 2026 (Mon), eligible products normally priced at ¥10,999 (tax included) will be sold at a special price of ¥2,999 (tax included).

This release will primarily introduce two models: "Polarized Sunglasses [Gray]" and "Photochromic Polarized Sunglasses [Light Gray]". Other colors and lineups can be found on their respective product pages.

A Natural Wellington Design Considering Japanese Facial Structures

When choosing sunglasses, many people feel that "the frames look like they're floating off their face," "the width feels tight," or "they don't blend well with their facial features."

Dujup's new sunglasses feature an Asian fit specification that considers the facial lines of Japanese people. We aimed for a natural fit by paying attention to the shape of the front part and the balance with the face width.

The design uses the Wellington style, which is resistant to trends and easy to match with a wide range of styles.

They are easy for those who don't usually wear sunglasses to incorporate and blend well with everyday fashion such as T-shirts and shirts, as well as sportswear and outdoor styles.

These sunglasses are designed for a wide range of uses, from daily activities like walking around town and traveling, to active scenes such as driving, fishing, golf, camping, and cycling.

"Polarized Sunglasses [Gray]" Reduce Reflections from Water Surfaces and Roads

The "Dujup Polarized Sunglasses [Gray]" feature polarized lenses with 99% polarization.

They reduce reflected light from water surfaces, roads, and glass, minimizing glare and improving visibility. They support various outdoor activities such as driving on sunny days, fishing, golf, cycling, and hiking.

In fishing, they make it easier to see underwater conditions by reducing reflections from the water surface, and in driving, they reduce glare from reflections on the road and around the windshield. They are also suitable for scenes where you spend long hours outdoors, such as golf and cycling.

Additionally, the lenses are UV400 compliant, cutting 99.9% or more of UV rays. They are easy to incorporate not only for strong summer sunlight but also for daily UV protection regardless of the season.

The calm gray lens color is easy to match with everyday fashion as well as sports scenes. While prioritizing functionality, we also focused on ease of everyday use.

"Photochromic Polarized Sunglasses [Light Gray]" Change Lens Darkness According to Light Environment

The "Dujup Photochromic Polarized Sunglasses [Light Gray]" feature lenses that combine photochromic and polarizing functions.

Outdoors, the lens darkness changes according to environmental conditions such as UV ray intensity, adapting to scenes with varying brightness.

Furthermore, the 99% polarization function reduces glare and reflections from water surfaces, roads, and glass. By combining photochromic and polarizing functions in one pair, they are convenient for outings on days when light conditions change due to weather or time of day.

With UV400 compliance, they cut 99.9% or more of UV rays regardless of lens darkness. They are suitable for spending long hours outdoors, such as during outings from morning to evening, traveling, fishing, golf, and camping.

The light gray lens color is characterized by a natural style that does not make the eyes appear too dark and suppresses the strong impression typical of sunglasses.

They achieve a balance of everyday usability and functionality, making them a model that is easy for those who are hesitant about dark-lensed sunglasses to try.

* The change in darkness of photochromic lenses varies depending on environmental conditions such as UV intensity and temperature. Generally, they tend to become darker in colder environments and lighter in warmer environments.

* In environments like car interiors with UV-cut glass, the photochromic reaction may be weakened. The polarizing function is separate from the lens darkness change.

TR-90 Frame Prioritizing Lightness and Flexibility

The frame material uses TR-90, which offers both lightness and flexibility.

We aimed for a lightweight feel that is comfortable even during long drives, trips, or outdoor activities, creating a design that is easy for daily use.

It also ensures a secure fit during active movements. They can be used in various active scenes such as running, cycling, golf, and fishing.

When it comes to sunglasses, not only the design but also "whether they can be worn for long periods" is important.

Dujup focuses on a balance of lightness, fit, and ease of integration into daily life, considering both short-term use in urban settings and long-term use during travel and outdoor activities.

One Pair of Sunglasses for Daily Life to Outdoor Activities

With this new release, Dujup aims to create eyewear that can be naturally used as an extension of daily life, rather than sunglasses used only for specific occasions.

From commuting and shopping, to weekend outings, driving, traveling, fishing, camping, golf, and cycling.

By combining a simple Wellington design with functions like polarization and photochromic polarization, they cater to various lifestyles and usage scenarios.

These are not only ideal for summer UV protection but also suitable for those who spend a lot of time outdoors regardless of the season.

Furthermore, their simple design makes them easy for people of all ages to use, making them a great gift option for birthdays, anniversaries, Father's Day, Mother's Day, and other occasions.
