Abstract

Handsfree fieldglasses providing increased clarity and magnification of a visual target in an outdoor application are disclosed. The handsfree fieldglasses can include eyeglasses, binoculars, and a customized connector coupling the eyeglasses and binoculars. The eyeglasses may include prescription lenses and/or polarized lenses. The lenses can have antireflective coatings, hydro-phobic coatings and/or a reduced or substantially flat base curve. The binoculars include adjustable separate lens arrangements having lengthy or infinite focal lengths to be placed against each eyeglass lens. The connector includes multiple fixed attachments and adjustable components such that the binoculars can be custom adjusted to rest against the eyeglasses and also to flip away from the eyeglasses while remaining coupled thereto. While resting against the eyeglasses, a user simultaneously perceives a full field of view having a magnified central portion and non-magnified outer portion. Perforated sideshields are used to reduce side glare while also permitting air passage.

Claims20

Dependent claims

A handsfree optical device adapted to provide for increased clarity and magnification of a visual target in an outdoor application, comprising:

sunglasses adapted to be worn on the head of a user, said sunglasses including two polarized lenses coupled to a lightweight frame having a frontal portion and two adjoining arms, said polarized lenses each having a base curve that is less than about six diopters and antireflective and hydro-phobic coatings applied thereto;
at least two perforated sideshields coupled to said lightweight frame and oriented along said adjoining arms, said perforated sideshields being arranged to reduce incoming glare from the sides of said sunglasses while also permitting the passage of air therethrough;
binoculars adapted to be placed against the outer substantially flat surfaces of said polarized lenses, said binoculars including two separate optical arrangements coupled to a central shaft, wherein at least one of said separate optical arrangements is adapted to be rotated about said central shaft such that the angle defined by said two separate optical arrangements and said central shaft is adjustable, and wherein both of said separate optical arrangements have infinite focal lengths;
and
a connector adapted to couple said binoculars to said sunglasses, said connector including a first fixed attachment connected to said lightweight frame, a second fixed attachment connected to said binoculars, and one or more adjustable components disposed therebetween, said one or more adjustable components being adapted either alone or in combination to permit a customized placement of said binoculars against said sunglasses, and to permit said binoculars to be flipped up and away from said sunglasses while remaining coupled thereto,
wherein said sunglasses and said binoculars are adapted to operate in conjunction with each other to create a full field of view for said user, said full field of view having a central portion that is magnified and an outer portion that is not magnified, wherein said user can observe both said visual target in said central portion and a separate object in said outer portion simultaneously and without detriment to each other.

3 more elements

A method of viewing objects underwater, comprising:

wearing by a user a handsfree optical device including:
eyeglasses adapted to be worn on the head of said user, said eyeglasses including two polarized lenses coupled to a frame having a frontal portion and two arms, said polarized lenses each having a base curve that is less than about six diopters,
a set of optical loupes adapted to be placed against the outer surfaces of said polarized lenses, said set of optical loupes including at least two separate lens arrangements, wherein each of said at least two separate lens arrangements have focal lengths greater than about ten feet, and
a connector adapted to couple said set of optical loupes to said eyeglasses, said connector being adapted to permit said set of optical loupes to be moved from a first stable position against said eyeglasses while coupled thereto to a second stable position away from said eyeglasses while remaining coupled thereto, wherein said eyeglasses and said set of optical loupes are adapted to operate in conjunction to create a full field of view having a central portion that is magnified and an outer portion that is not magnified;
moving the head of said user such that said handsfree optical device is directed toward a region that is at least partially underwater;
and
observing at least one underwater object at said region through said handsfree optical device, wherein observation is made of said first underwater object through said central portion of said full field of view and said first underwater object or one other object through said outer portion of said full field of view simultaneously.
