Heat, humidity and physical exertion in the field can all be the culprits of lens fogging - the enemy of a successful day's shooting. These Uvex Acadia Shooting Glasses feature the Uvextreme Plus anti-fog coating for fog-free vision that lasts up to 10X longer in any environment. The frame is sporty and lightweight, but also provides excellent comfort and high-performance protection. The integrated hinge provides a custom fit and effective open/close temple control.
