Deluxe Magna-Visor

This high quality tool includes the ability to use any one of
four different self-contained magnifications. Each visor has a
permanent fixed lens along with a unique fold-down lens and
pivoting outside loop. By modifying the different combinations
you can activate magnifications of 1.8X, 2.3X, 3.7X and 4.8X. The
Magna-Visor can be adjusted to a comfortable fit by using the
proven hook-and-loop system on the headband.
