RU2274439C1 - Antiglaring spectacles for drivers - Google Patents

Abstract

FIELD: protective devices for the eyes.

SUBSTANCE: spectacles comprises rim, glasses, and darkening semitransparent screens that overlap a part of the glasses. The darkening semitransparent screens are applied to the left halves of the both glasses of the spectacles from the side of oncoming vehicles from the vertical symmetry axis, passing through the optical center of the glasses, to the spectacles rim. The bridge between the glasses has two slides and adjusting screw with left and right threads for adjusting the distance between the centers.

EFFECT: expanded functional capabilities.

Description

The invention relates to devices for protecting the eyes of car drivers from being blinded by headlights of oncoming vehicles when driving on the highway at night.

The closest technical solutions adopted for the prototype are anti-glare glasses for car drivers, containing eyeglass frames, glasses and dimming translucent screens that cover part of the glasses, while dimming translucent screens are located on both glasses of glasses in one direction from their optical centers (see . RU No. 2088190, class A 61 F 9 / 02.1997).

The disadvantage of the prototype is that the sectional dimming filter screens are not enough to reduce the luminous flux from going towards the transport.

The objective of the invention is to reduce eye fatigue from being blinded by headlights of oncoming vehicles, and as a result, reducing accident rate on tracks at night, as well as creating universal anti-glare glasses with the possibility of establishing center-to-center distances between pupils from 62 to 78 mm on the same glasses.

To solve this problem, anti-glare glasses for motorists have been proposed, containing a frame of glasses, glasses and darkening translucent screens that cover part of the glasses, while darkening translucent screens are located on both glasses of glasses in one direction from their optical centers. Moreover, the dimming translucent screens are applied to the left halves of the glasses from the oncoming transport side from the vertical axis of symmetry passing through the optical center of the glasses to the spectacle frame. At the same time, two runners and an adjustment screw with left and right threads for selecting the center-to-center distance are installed on the bridge between the glasses with a frame. Dimming translucent screens are applied by spraying or by gluing a polymer translucent tape on the glasses.

To clarify the invention, a drawing of the appearance of anti-glare glasses for motorists.

Anti-glare glasses contain a spectacle frame (3) with glasses (2), on the surface of which darkening translucent screens (1) are applied on the left halves of the glasses from the oncoming transport side from the vertical axis of symmetry passing through the optical center of the glasses to the spectacle frame. On the nose between the glasses with a frame there are two runners (4) with openings for moving the runner (6) and an adjusting screw with left and right threads (5) for selecting the center distance. The distance between the pupils is S.

Points are used as follows.

When leaving the city on a highway, the driver puts on glasses and watches the road, using the bright, unshaded part of the glasses. In the process of convergence with oncoming traffic, the driver, with a slight turn of his head, begins to view the transport through the darkening translucent screens of the glasses before the departure. Turning the head is 1-2 degrees and does not affect the difficulty of viewing. During this maneuver, the oncoming lane remains in the darkened part of the glasses, and the lane of the driver himself is not darkened and is clearly visible.

The selection of points is as follows. Wearing glasses, look at any fire or at a room light. Then they turn their heads left and right. The change in the center-to-center distance between the glasses of the glasses is carried out with the help of an adjusting screw moving along the skids of the rimmed glass. If the light from the bulb crosses the shading line of the glasses at the same time in both eyes, then the glasses are correctly selected.

Points are selected individually with the help of an oculist. EFFECT: reduction of eye fatigue from blinding by headlights of oncoming vehicles, reduction of accident rate on tracks at night.

Claims (1)

Anti-glare glasses for motorists, including eyeglass frames, glasses and dimming translucent screens that cover part of the glasses, while dimming translucent screens are located on both glasses of the glasses one side of their optical centers, characterized in that the dimming translucent screens are applied to the left halves of the glasses sides of the oncoming transport from the vertical axis of symmetry passing through the optical center of the glasses to the spectacle rim, while on the bridge between the glasses with the rim there are two polo for and adjusting screw with left and right threads for the selection of center distance.
