Computer Access - designed for computer users requiring near and intermediate focus. It has large viewing area for both near and intermediate distance which allows wearers to have a wide, clear, uninterrupted view of their entire work space – from the keyboard and reading materials in front of them, to the monitor and beyond. Can't be used for driving in most cases.
