Gradient color prescription glasses

Quick answer：

Gradient color prescription glasses are a type of eyewear designed for individuals with myopia. These glasses have lenses with a color gradient, which can provide a more comfortable viewing experience and potentially reduce eye strain. The gradient starts lighter at the top of the lens and becomes darker towards the bottom, allowing the eyes to adapt more gradually from the bright sky to the darker ground. This feature is especially beneficial for those who spend a lot of time outdoors.
