Varilux Computer or Task Specific Lens
The Varilux Computer lens is a progressive lens that is kind of built like a two story house. There is the bottom floor which is a wide area of reading prescription the next floor is an equally wide area of intermediate power and the small roof contains a distance prescription.
This lens allows for easy use while doing computer work, through the top of the lens for your monitor, the bottom of the lens for your book work, and there is just enough distance at the top to make out who is calling your name from across the office.
This lens also has comes with an Anti-Reflect coating to reduce glare from your screen and over head lights.
