Depth perception is slightly altered
with 3D optical design. Continued
usage will improve comfort level.
Install bifocal lenses so that only the
upper third is for distance and lower
two-thirds is for reading. Adjust the
nose bridge so that frame sits higher
on nose. Then lower the height
adjustment. This will ensure that
the binocular viewing system will
be positioned in front of the reading
part of the lenses.
