Gradient sunglasses are sunglasses where the lens tint transitions gradually from darker at the top to lighter or clear at the bottom. This two-tone effect is created by adding a metal oxide to the lens material during manufacturing.
Understanding Gradient Lenses
-
Two-Tone Design: The defining feature is the visible transition in tint density. The top portion is darkest, offering maximum protection from overhead sunlight. The bottom portion is lighter, allowing more light to pass through.
-
How They're Made: The gradient effect is achieved during the lens manufacturing process by applying a special dye or coating that gradually fades in density.
Benefits of Gradient Sunglasses
-
Versatility: They are suitable for both indoor and outdoor use. The lighter bottom portion allows you to see clearly while looking down, making them convenient for activities like driving, reading, or looking at your phone.
-
Reduced Glare: The darker upper portion effectively blocks glare from above.
-
Fashionable: Gradient lenses offer a stylish and modern look.
Types of Gradient Sunglasses
There are different types of gradient sunglasses, including:
- Single Gradient: A smooth transition from dark to light.
- Double Gradient: Dark at the top and bottom, with a lighter section in the middle.
- Mirror Gradient: A mirror coating on the top portion of the lens with a gradient tint.
Gradient sunglasses offer a practical and fashionable eyewear option, providing sun protection while maintaining clear vision in varying light conditions.
