Glasses

Read the map clearly at racing speed

Mästarn sports reading glasses are intended for orienteers and runners who need magnification to read a map while moving. Freeway combines a sports frame with ventilated lenses designed to reduce fogging as exercise intensity increases.

Choose complete Freeway glasses if you need both the frame and lenses. Check the available magnification strengths carefully before ordering. If you already own a compatible Freeway frame, replacement lenses allow you to change magnification or replace damaged lenses without buying another complete pair.

The hollow Freeway lenses include ventilation openings. Highway provides a solid, full-coverage lens alternative designed for compatible Freeway frames. Read the product details to confirm frame compatibility, available powers or colors and exactly what is included. Replacement-lens products do not include a frame unless the page explicitly says otherwise.

Fit and field of vision are important when choosing sports glasses. Consider how the glasses interact with a hat, headband or compass magnifier. Follow the cleaning instructions and use an appropriate protective case to reduce scratching and preserve clear vision.
