Far and near progressive Lenses : Whether you're looking down to read or looking up to catch a glimpse of the television, you can keep your glasses on at all times with progressive style lenses.
The lenses will been automatically darken to a sunglasses tint when exposed to UV sunlight. Lenses will begin to clear as soon as they are away from UV sunlight, and will be noticeably lighter and mostly clear within a few minutes. They absorb UV radiation that can otherwise damage your eyes. They are an excellent solution for people who hate constantly switching between their reading glasses and their shades.
