Orion 5942 AstroGoggles
Astrogoggles help your eyes become dark-adapted before you observe the night sky through a telescope or binoculars. Wear AstroGoggles inside for about a half-hour before observing, or while setting up your telescope, to make your eyes dark-adapted. Deep red plastic lenses filter out the wavelengths of light that ruin dark adaptation. Large enough to wear over eyeglasses. Air vents help prevent fogging
