ABSTRACT:
A variable density polarizing attachment for shields combined with spectacles having polarizing lenses is provided along with a method of making variable density shields. A polarizing rotary disc is attached to standard shield adding optionally: polarized eye-protection and/or variable density shading with standard polarized lens' spectacles. The rotary disc is mounted on the inside of the shield and adjacent to standard polarizing spectacles' lenses. By rotating the disc the combination converts the sheidl to variable density. The set of snaps utilized to mount the rotary disc is modified to allow some air inside the shield, and/or to gyrate the disc.
