ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to protective eyewear and, more specifically to fully adjustable glare reducing eyeglasses for three to six month post-operative lasik surgery patients. The present invention utilizes two selectively rotatable visual aspect gear wheels with each having a plurality of various sized apertures that are aligned at the user's discretion with viewing recesses on gear mounting plates in front of each of the user's eyes in order restrict glare accordingly and increase visual capabilities during recovery. The frame of the present invention has removable extendible ear arms and a gear driven telescoping front lens and ear arm support bracket to allow the user to adjust the width of the glasses accordingly.
2. Description of the Prior Art
Numerous protective eyewear has been provided in prior art. Typical of these is U.S. Pat. No. 2,064,812 issued to Samuel E. Bouchard on Dec. 22, 1936.

Inventor: S. E. Bouchard
Issued: Dec. 22, 1936
In a pair of goggles, two eye units, an extensible bridge connecting said eye units, each eye unit having a polarizing element fixedly mounted therein, and a worm for rotating said rotatable element, extensible means for connecting said worms whereby said rotatable elements can be rotated in unison and means for rotating said extensible means.
U.S. Pat. No. 2,380,481
Inventor: E. D. Tillyer et al.
Issued: Jul. 31, 1945
An optical mounting comprising spaced cells aligned with the two eyes, a pair of spaced light polarizing means mounted in each cell in holding means having peripheral gear teeth, a turn rod having worm gears engaging the teeth of the holding means of each cell, a quarter wave member positioned between the polarizing members in each cell and held in holding means for the wave member in each cell, said wave member holding means to be frictionally engaged by the holding means of the polarizing members to turn as a unit with said members, and being independently turnable with respect to the polarizing members by means of said central gear wheel.

Inventor: V. K. Eloranta
Issued: Aug. 21, 1951
In a variable density goggle, a lens and a lens mount assembly comprising a front housing having a forwardly extended portion inwardly spaced from the edge of said housing and having means provided right eye and left eye apertures and having, a rear housing, a unitary light-polarizing lens element having a right eye portion and a left eye portion positioned between said housings and within said forwardly extending portion, a spacer element fixedly positioned between said unitary lens and said rear housing and having means providing right eye aperture.
U.S. Pat. No. 3.944.346
Inventor: Anthony Shindler
Issued: Mar. 16, 1976
Spectacles having a face-formed readily separable two-section eyeglass frame front wherein a first forward section of the frame front supports a pair of fixed non-circular light-polarizing lenses and a rearward second section supports a rotatable light-polarizing lens in alignment with each forwardly disposed lens. A manually operable rear lens rotating mechanism is provided for selectively rotating the two rearward lenses in unison to simultaneously equally rotationally alter the orientation of axes of polarization of these lenses relative to axes of polarization of the fixed forwardly disposed lenses for correspondingly varying the intensity of light permitted to pass through each system of front and rear lenses of the spectacles.
U.S. Pat. No. 4,948,244
Inventor: Billy R. Jones
Issued: Aug. 14, 1990
Rotatable, multiple lens eye glasses having a frame by which a lens body is supported and by which the eye glasses are adapted to be worn by a person. The frame includes a circumferentially extending U-shaped channel member which rotatably receives a lens body therewithin. Means on said lens body for imparting rotation thereto. Said lens body having a plurality of magnifying lenses formed thereon, whereby rotation of the lens body brings a selected power lens into alignment with the eyes.
U.S. Pat. No. 5,210,552
Inventor: Patrick Baran et al.
Issued: May 11, 1993
A pair of variable density sunglasses include two lens elements of polarized material forming each lens. The other lens element is rotatable in a channel in the frame by manipulation of a gear mounted on the nose bridge, the gear teeth being engaged with gear teeth on the edge of the outer lens element. Rotation of the gear is limited by a peg extending from the back thereof into an arcuate channel on the nose bridge. The stationary inner lens is prevented from rotation by an edge tab extending into an opening in the lens channel through which the gear and rotatable lens engage.

Issued: Sep. 2, 1997
A sealed, polarizing lens assembly including a frame, a first light polarizing lens element, a second light polarizing lens element superimposed with the first lens element and rotatable in relation to the first lens element. The frame and the first element define a sealed chamber in which the second element is entirely enclosed and rotatable relative to the first pair of elements. Means for rotating the second internal element in the sealed chamber relative to the first pair of elements are provided. In one form the means for rotating the internal element in the seal chamber comprise a sealed gearing mechanism with user-accessible external actuators. The sealed, easily adjusted lens assembly of the invention prevents contamination of internal lens surfaces by dust and moisture, for example. The seal chamber can also be provided with a fluid or gas with desired optical or thermal barrier characteristics.

Inventor: Naoki Karasawa et al.
Issued: Nov. 24, 1998
A lens assembly is disclosed comprising at least first and second removably superimposed eyewear elements each comprising a frame member including framing means for at least one lens. Each frame member has a first longitudinal curvature in an unassembled condition of the lens assembly, and at least the at least second eyewear element further has a flexible intermediate portion providing for longitudinal flexibility of the at least second eyewear element along a transverse medial axis thereof such that the at least second eyewear element is deformable to defame a second longitudinal curvature complimentary with the first longitudinal curvature of the at least first eyewear element when the at least first and second eyewear elements are removably axially superimposed in longitudinal alignment.
