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.
