Abstract: An inexpensive method and apparatus for modifying the optical characteristics of blank lenses to convert them into regular lens spectacles in order to enable a prospective purchaser of eyeglass frames to fully see himself/herself in the mirror when trying on the frames to be certain as to how they will look when wearing the frames. The present invention relates to an eyeglass frame tester kit which can be used to evaluate a particular frame among others. Correction means are temporarily adhered to the blank lenses of each pair of frames selected. This permits the client to get a more realistic image of how the completed prescription will look because with the corrective ocular means affixed to the blank lenses, the lens functions as a normal lens providing the optical correction required to enable the wearer to see clearly.

Abstract: Artist's eyeglasses having a clear section in the lens and a diffused section in the same lens suited for viewing an object to be painted or drawn through the diffused section and seeing that object in its most basic shape, shifting one's gaze away from the object to the painting medium (canvas) and simultaneously shifting one's eyes to the clear section while the basic shape is fresh in the mind, and transferring that basic shape onto canvass. The glasses also have adjustable shading and lighting shields over the frame and temple arms to permit the artist to vary the shading and lighting at the point of perception as best suited for artistic needs and purposes.

Abstract: Sunglasses with vision directing sections comprise a frame with temples to hold the frame on the wearer's face and lenses in the frame. Each lens is tinted on its front and rear surfaces and one of those surfaces is further coated with a reflecting layer except in the area of the vision directing section. The sunglasses provide highlighted vision through the vision directing sections so that the wearer's vision is directed to that portion of their field of vision. The sunglasses are useful in a variety of activities where it is beneficial to direct attention to a select portion of a person's field of vision or where it is desirable to have a less shaded view through the sunglasses.

Abstract: A pair of eyeglasses is provided for sports training, and more specifically for training the player to keep the player's eyes on an approaching ball for batting or for swinging a racket.

Abstract: A light transmission adjustable spectacle structure comprises for each lens set thereof a fixed polaroid lens and a rotatable polaroid lens which has a number of non-polarized aperture-like areas formed thereon so that when the rotatable lens is rotated relative to the fixed lens to have the polarization directions thereof normal to each other, light is only allowed to pass through the apertures of the rotatable lens. This significantly cuts down the transmission of light through the lens set. In addition, by suitably selecting the size of the aperture-like areas, the depth of focus of retinal image occurring to a wearer of the spectacles is properly increased to provide a more clear view to the wearer.

Abstract: There is disclosed a simulator for simulating a reduced peripheral field of view for the eyes of a normal user. The simulator consists of a frame having a front section upon which two eye pieces or binocular tubes are mounted. The frame has adjustable temple pieces which are adjustable in the horizontal direction and are adjustable to provide an angle with respect to the vertical so as to adjust the tilt of the frame when it is being worn by the user. Each binocular tube is associated with a variable iris diaphragm which enables the practitioner to adjust the opening to thereby simulate a different field of view according to the particular visual defects associated with a handicapped user. The simulator has left and right shields depending from the temple sections to prevent side vision when the frame is being accommodated by the user. In employing the simulator the device will provide an accurate replica of a reduced field of view such as that existing in a patient having tunnel vision.

Abstract: An improved optical device in combination with means for holding the device in position before the eye including an optical device formed of an opaque mask for mounting before the eye, a horizontal transparent area extending substantially across the mask centrally thereof, an array of discrete circular transparent areas on the mask, the array being disposed below the horizontal transparent area and each circular area having equal diameters of between 0.5 and 1.2 mm. is characterized by an increase in the total aperture of the transparent areas on those portions of the opaque mask where the eye-to-mask distance increases thereby permitting a greater field of vision while limiting the influx of light.

Abstract: A light intensity filter for a telescope or other optical instrument viewed by the human eye is formed of an opaque material having a plurality of holes or windows. These windows transmit a reduced amount of light to the image-forming optical component. The area of the windows relative to the area of the optical component is selected to the light intensity being imaged. The filter is especially useful for telescopes and the like, wherein the image is viewed by a human observer and the light source is momentarily of great intensity. Under these conditions the filter prevents temporary blindness of the observer due to excessive illumination, for example, tracking a moving object across the sun.

Abstract: Disclosed is a pair of eyeglasses with laterally slidable vision screens in each of the eyeglass openings. The vision screens have an opaque lower portion and a transparent upper portion, and have a clear see-through vertical slit which extends into the lower portion. By adjusting the vision screen so the golf ball, before it is struck, is viewed through the slits, and by keeping the ball in such view during the swing, the golfer controls his head position. A second form of my invention is shown which clips onto the user's regular eyeglasses, and a third form attaches adhesively to the lower portion of regular eyeglasses.
