Gradientläätsed

Gradientläätsed, also known as gradient lenses or graduated tint lenses, are eyeglasses that feature a gradual change in tint from top to bottom. Typically, the top of the lens is the darkest, transitioning to a lighter shade in the middle and often remaining clear or very lightly tinted at the bottom. This design provides functionality for different visual needs within a single pair of lenses.

The primary purpose of gradientläätsed is to offer protection from bright light while allowing for clear vision at various distances. The darker top portion is effective for blocking sunlight when looking upwards or straight ahead, reducing glare and eye strain in bright outdoor conditions. As the wearer looks downwards, such as to read a book or a device, the lighter or clear bottom portion allows for unimpeded vision without requiring the removal of the glasses. This makes them a popular choice for sunglasses and for individuals who frequently switch between looking at distant objects and reading.

Gradientläätsed are manufactured using various tinting techniques. One common method involves dipping the lens into a tint solution, where the concentration of the dye is higher at the top, creating a darker shade that gradually fades. Another technique involves applying a tint to the surface of the lens in a gradient pattern. The specific color and gradient pattern can be customized to suit aesthetic preferences and functional requirements. While commonly seen in sunglasses, gradient tints can also be applied to prescription lenses for indoor use, offering subtle light management.
