The WTD is designed for Korean riders.
Our roads have a lot of topographical features, so the sun and shade appear repeatedly.
Riders in Korea enjoy riding during early morning rush hour and night time after their daily lives.

Designed for these characteristics, WTD's discoloration lenses have somewhat brighter characteristics than regular discoloration lenses.
As a result, the WTD discoloration lens has a slightly visible darkness even when it is as dark as possible after discoloration.
Thanks to the specification of these lenses, they can be worn at sunset or at night.
