Have you forgotten your sunglasses and you are going to a snow area? There is an emergency solution. It is an Eskimo invention to prevent damage from sunlight in situations of maximum exposure. It consists of placing an opaque screen on glasses or equivalent support, making a small longitudinal groove on each small screen. The result: we have lower focal amplitude, but we greatly reduce the impact of sunlight on the eyes. It is more effective than dark glasses, although of course it is always better to wear quality sunglasses! Enjoy the snow safely!!!
