Sunglasses are consumables that can get scratched by branches or when wiping them. It's great that replacement lenses are readily available at a low price and that they can be kept in good condition. They block light from the sides, so you can feel safe even at high altitudes or in spring mountains where UV rays are strong.

OAKLEY|Latch (Low Bridge Fit)
It comes with a clip that can be hung around your neck, making it super convenient and fashionable!

Being able to hang sunglasses around your neck is not only fashionable, but also extremely convenient when using them in the mountains. When you want to take your sunglasses off briefly during a hike, simply resting them on your head can be risky as they might fall off. The Latch securely fastens them.
The frame material is lightweight O Matter™. The Square O metal icon accent is cool, and the curve of the round lenses creates a unique atmosphere. The lenses are equipped with Oakley's proud Prizm™ lens technology. By enhancing color tone and contrast, the boundaries of the surrounding environment become easier to see, resulting in a clear view of even the smallest details. Polarized lenses and Iridium® lenses are also available as options. Oakley's genuine prescription lenses can also be fitted. The curve of the round lens creates a unique atmosphere.
"Low Bridge Fit" is an Asian fit type. The lens shape, frame angle, and nose piece fit comfortably even on low noses. This is sure to please many Japanese people. There is also a wide range of colors available

I've been using these sunglasses for many years because of their design, which is great for both outdoor activities and casual use in the city. They're lightweight, and the lenses block just the right amount of light, so I often forget I'm wearing sunglasses because they feel so natural. I highly recommend them because you won't even notice you're wearing them for extended periods!
