A custom-fitted economical eyeware frame constructed at the site of dispensing from a minimum inventory of parts includes lenses of predetermined size and power encompassed by appropriate eye wires, and a bridge assembly, temple end pieces and temple ear stems. Upon selection of an appropriate bridge assembly, any, or all, of the remaining parts may be individually adjusted to custom fit the individual's interpupillary distance requirement. The construction of the eyeglass frame may be readily accomplished by an eyewear professional at any location.

A pair of goggles comprises a goggles frame with a pair of eyepiece holders, a nosepiece extending between inner end portions of the eyepiece holders, and a head strap extending between outer end portions of the eyepiece holders. Each eyepiece holder has an opening with an eyepiece unit fitted therein, the eyepiece unit having an overall length less than length of the eyepiece opening to permit relative movement therebetween to vary interocular spacing between the eyepieces to accommodate persons having eyes at different spaces. Guides are provided at outer end portions and intermediate portions of the eyepiece units and eyepiece holders to ensure axial movement of the eyepiece units with respect to the eyepiece holder with negligible rotation therebetween. A locator is provided to limit relative movement between the eyepiece holder and eyepiece unit. The locator can be fitted between adjacent outer end portions of the eyepiece holder and eyepiece unit to prevent movement of the eyepiece unit relative to the eyepiece opening.

Disclosed is an improved bridge structure of spectacles frame, which frame has a bridge and a transverse piece both connecting two rims side by side. It comprises a joint piece and opposite arms, each arm being fixed to one or the other rim at one end, and being fixed to the joint piece at the other end so as to permit the arms to rotate relative to each other. The rotatable bridge permits the frame to yielding twist when exterior force is applied thereto, and to restore to its original shape when the exterior force is removed therefrom.

An adjustable eyeglass frame includes a face bar with opposite ends and a pair of lens subframes each mounting a nose pad assembly and a temple. The lens subframes are adjustably mounted on the face bar by mounting structures slidably received in channel portions. The lens subframes can be locked in place with respect to the face bar by interlocking lands and grooves, by crimping or by frictional engagement. An alternative or modified embodiment eyeglass frame includes nose pad assemblies which are slidably, adjustably mounted on the face bar. In another alternative or modified eyeglass frame, the lens subframes include top-mounted tubes for telescopically receiving end portions of the face bar.

An adjustable Pd lens frame carries a pair of prism lenses is adjustably positioned to a normal stationary position with respect to a computer monitor screen. The lenses provide "base in" for each eye and plus optical power to reduce both accommodative demand and convergence demand.

The invention provides spectacles in which the distance between two lens frames (1)(2) is variable and which has holders (7)(7a) on the lens frame, a bridge (8) slidably fitted in the holder for connecting the lens frames together and holding means (9) for determining the effective length of the bridge.

Eyeglasses which have removable and replaceable lenses to meet individual vision requirements with respect to focal length and strength. In one embodiment, the lenses are slidably and removably mounted to a rod-like holding element. The position of the lenses relative to one another can be changed by sliding the lenses along the holding element. This allows the eyeglasses to accommodate differences in the eye spacing among people. The lenses can also be removed and replaced should an individual desire or need lenses of different focal lengths or strengths.

An eyeglass mounting structure for temporarily securing eyeglasses within a protective mask. The eyeglasses include a frame having a bridge between the lenses, and a plastic hinge connects the hinge to a carrier. A suction cup has a screw extending therefrom, and holes in the carrier allow the screw to be threaded into the carrier. More than one such hole will allow adjustable placement of the eyeglasses with respect to the suction cup.Further, the bridge is made thin to act as a hinge and allow the eyeglasses to be partially folded to fit within a curved mask. The hinge is bifurcated to allow easy folding without requiring lateral bending of the hinge.

Eye glasses for experimentation and testing comprising a frame on which adjustable lens holders can be shifted.They comprise a frontal mounting 1 which is extended downwardly in its central portion in the direction of the patient's nose by a bar 5 of short length and on which glides a vertically adjustable support 6 for engagement with the patient's nose or his regular eye glasses which the patient has to wear during the testing.Application of the eye glasses for allowing tests to be taken with a patient who has to get new glasses with different corrective lenses and different positions of said lenses with respect to the eyes of the patient.

Spectacles for giving a two-dimensional picture a three-dimensional appearance. The spectacle frame has two refracting lenses mounted therein for pivotal movement around vertical axes through equal angles in opposite directions. The spectacles have arms attached to the lenses with toothed wheels between them for driving the arms in the opposite directions, one of the arms being driven by an adjusting head accessible by the wearer of the spectacles. The spectacles can have bows thereon for wearing in a conventional manner or can have clips for attachment to conventional spectacles.
