LeaguE Unveils Manual Dimming Sunglasses for Optimal Vision in Any Condition

Tokyo, Japan (July 14, 2026) – 株式会社LeaguE (LeaguE Co., Ltd.) has commenced pre-sales for its innovative “9-stage manual dimming sunglasses” on the crowdfunding service Machi-ya. These sunglasses feature a unique manual adjustment mechanism, allowing wearers to control lens darkness across nine stages with a simple finger operation.

Unlike conventional photochromic lenses that react to UV light, these new sunglasses offer instant and independent brightness control. This design addresses common issues such as lenses not changing color inside UV-cut car interiors or slow adjustment times. The manual dimming ensures that visibility can be optimized instantly, whether entering a tunnel or transitioning between varying light conditions.

The sunglasses are equipped with a dial on the side of the lens, enabling wearers to precisely adjust the lens tint. This functionality ensures clear vision in diverse environments, from bright sunny days to cloudy conditions and even at night.

Product Features:

Point 01: Instant Dimming for Enhanced Safety

The dial on the side of the frame allows for gradual adjustment of lens darkness. As the dimming is not dependent on UV light, the sunglasses function effectively even within UV-cut vehicles. This feature is particularly useful for drivers transitioning from bright outdoor conditions to tunnels or navigating roads with frequently changing light intensity, providing immediate vision optimization.

Point 02: All-Weather All-in-One Solution

These sunglasses eliminate the need to carry multiple pairs. They can be adjusted to a darker tint for sunny weather, a medium tint for cloudy days or evenings, and a lighter state for nighttime use. This makes them suitable for a wide range of activities and environments, including city walks, driving, travel, camping, and beach outings.

Point 03: High-Resolution TAC Polarized/ND Function

Featuring TAC polarized lenses with over 95% polarization, the sunglasses enhance the clarity of object outlines and colors. This is beneficial for activities such as driving in strong sunlight, fishing, golfing, cycling, and other outdoor pursuits. The integrated ND (Neutral Density) function controls the amount of light entering the eye without significantly altering the surrounding colors.

Point 04: Robust UV400 Eye Protection

The sunglasses offer UV400 protection, blocking 99.9% of harmful UV rays, while the 9-stage dimming function allows for brightness adjustment suitable for various scenarios. They are ideal for daily commutes, long drives, and extended outdoor leisure activities where prolonged sun exposure is expected.

Point 05: Detachable Lens Unit for Easy Maintenance

The lens unit is designed to be detachable from the frame, allowing for thorough cleaning of all parts, even after exposure to sweat, sebum, or dust. This modular design also means that if the lenses become scratched, only the lens unit needs to be replaced, rather than the entire frame.

Point 06: Sophisticated Design for Adults

Moving beyond a purely gadget-focused aesthetic, the sunglasses feature a classic round shape that complements everyday attire. The frame is crafted from black metal, offering a refined look that pairs well with casual wear, as well as jackets and suits, making them suitable for commuting or travel.

Point 07: Durable Yet Lightweight Comfort

Constructed with a lightweight and durable aluminum alloy frame, the sunglasses weigh approximately 43g, minimizing discomfort during prolonged wear. Adjustable nose pads ensure a secure and stable fit, preventing slippage.

Point 08: Optimal Solution for Eyeglass Users

The lens unit can be removed and replaced with prescription lenses at a standard optician. This feature eliminates the need for users to wear over-sunglasses or switch to contact lenses when using sunglasses.

Note: The feasibility and cost of prescription lens replacement may vary by optician. Please consult with your chosen store in advance.
