One of the best qualities of modern outdoor glasses is that they can be coated with a product that transitions from clear to tinted according the strength of the sunlight. This eliminates the need to put on sunglasses covers whenever the sun comes out of hiding. It saves eyesight while walking and also reduces glare whenever driving a car. New transition lenses can be a real help because the pace of life continues without any interruption.
Exposure to direct sunlight is not good for the eyes, and while glass can reduce ultraviolet exposure, only quality tinting eliminates UV exposure to the eyes. The product protects the eyes from bright light while protecting the body from the shock of sun glare. It even protects the eyes from sudden transitions in artificial lighting, as intense and bluer light sources are becoming more common.
