Using the Eye Shades
When Wearing Eyeglasses
Use with the eye shades in the normal, folded-down position. This will
prevent the eyeglasses from being scratched.
When Not Wearing Eyeglasses
Extend the folded eye shades in the direction of the arrow to prevent
extraneous light from entering between the eyepieces and eyeglasses.
