Reading detailed maps with clarity while running is an age old problem in orienteering. Fogging from perspiration or rain has typically driven glasses to be slimmer, sacrificing robust construction and a secure fit.
The Frenson Focus FogFree orienteering glasses are true anti-fog sports glasses with ventilation holes to prevent the glasses from fogging up, especially when it's raining or humid.
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.
Current magnificiations include +1.0 and +3.0. See Vavrys for other magnifications.
