Gradient Lenses

Featuring a tint that gradually transitions from dark at the top to lighter at the bottom (or side-to-side), gradient lenses allow for balanced vision in mixed lighting. The upper portion blocks overhead sunlight, while the lower section remains clear for viewing dashboards, maps, or instruments without removing the glasses.

Advantages

• Perfect for driving and urban environments
• Stylish appearance suitable for casual and professional settings
• Reduces sky glare while maintaining visibility below
• Great for variable light conditions

Limitations

• Less effective in uniformly bright environments
• Limited protection from low-angle sun (e.g., sunrise/sunset)
