ED Glass
Your Carson 3D-ED binoculars contain ED Glass (extra low dispersion glass) in their lenses.
This ED Glass helps prevent chromatic aberration (fringes of color that appear around the
viewing image).
Focusing your binoculars:
Carson 3D binoculars have a center focus wheel and an independent right diopter eyepiece to account
for small differences in the strength of each eye. Please follow the steps below to focus properly:
1. Adjust the interpupillary distance.
2. Rotate the right eyepiece to its index mark and sight on a fixed distant object.
3. Cover the right objective (front) lens with your hand, then rotate the central focusing wheel until
the image in the left eyepiece is sharp.
4. Cover the left objective (front) lens with your hand then rotate the right eyepiece until the image is
sharp. (Note this setting for future use.)
5. Image should now be focused to your individual eyestrength.
