Abstract

A vision enhancing assembly including a carrier device and one or more magnification devices coupled to the carrier device is disclosed. The magnification device including a housing having an objective lens at a distal end and an eye lens at a proximal open end is disclosed. The housing includes an optical system including one or more objective lenses adjacent the distal end, and one or more eye lenses adjacent the proximal end, the optical system producing a desired level of magnification and a filtering system having at least one of at least one first lens or at least one second lens, wherein an optical density of the at least one first lens and the optical density of the at least one second lens is determined based on a magnification level of the optical system and a position of the at least one of the at least one first lens and the at least one second lens with respect to at least one of: the objective lens and the eye lens.

Dependent claims

A vision enhancing assembly, comprising:

a carrier device;
one or more magnification devices coupled to the carrier device, each of said magnification devices comprising:
a housing comprising:
a distal end and a proximal end;
an optical system comprising:
an objective lens mounted in said housing adjacent said distal end, and
an eye lens mounted in said housing adjacent said proximal end, said optical system achieving a specific level of magnification;
and
a filtering system comprising:
at least one of:
a first filter system comprising:
a first objective lens filter positioned within said housing external to said objective lens;
and
a first eye lens filter positioned within said housing external to said eye lens, said first filter system configured to:
attenuate a first set of wavelengths, wherein an optical density of said first objective lens filter and an optical density of said first eye lens filter combine to achieve at least a desired optical density associated with said first filter system wherein said optical density of said first filter system is determined based on the specific level of magnification;
and
a second filter system comprising:
a second objective lens filter positioned within said housing external to said objective lens;
and
a second eye lens filter positioned within said housing external to said eye lens, said second filter system configured to:
attenuate a second set of wavelengths, wherein an optical density of said second objective lens filter and an optical density of said second eye lens filter combine to achieve at least a desired optical density associated with said second filter system, wherein said desired optical density of said second filter system is determined based on the specific level of magnification of said optical system.
