Reading detailed maps with clarity while running is an age old problem in orienteering.
The top portion of the lens is used for distance vision and a magnification area at the bottom for close-range. You can read your map or bike GPS/computer while running, hiking or cycling.
The sports frame also provides some protection from glancing branches.
Features:
Current magnificiations include +2.5. See Vavrys for other magnifications.
