Abstract

Seamless glasses. Streamline-optimized, elastically clasping the head around the head, with a spring ring strap around the back of the head, the eye glasses without bridge connection over the nose firmly on the head and in the eye sockets holds.

Description

The invention relates to a pair of spectacles according to the preamble of claim 1.

The previously known glasses, sunglasses and goggles are usually placed from the front. The spectacle lenses hold on the head by a stiff nose bridge, which can be separated and reassembled if necessary and both sides, hinged, fixed or flexible earpieces. Variants are also available with textile straps around the ears or elastic straps around the head.

The conventional vision aids and standard goggles have the disadvantage that they are used in rapid head movements, eg. B. during sports or dancing, while working in exposed positions or in upside-down postures, easily slip off, fall down or can be thrown.

Previously available sunglasses have the disadvantage that, due to the lateral distances of the dark light filter glasses from the face, even with the narrower molds, an at least small gap remains, is incident through the light, which can cause disturbing reflections on the inner surfaces of the glasses. In unfavorable cases, laterally incident, unfiltered UV light can penetrate through the dilated pupils and unnoticed damage the retina of the eye. Often even more than without sunglasses with narrowed pupils and narrowed eyes.

More comfortable, open goggles always carry a certain risk that splinters or spin chips bounce off and fall into the eye from the side behind the glasses. The goggles with side panels provided against it are either provided with ventilation openings and / or have a larger volume with a shape that often interferes with a protective helmet and is a hindrance. The misting of the visible surfaces by condensate of sweat, which is released especially from the facial skin of the forehead and cheeks, can not be prevented by the small vents long. During strenuous work or in the cold, this often only works for a few seconds before the view through the viewing windows is severely impaired, forcing a brief removal of the glasses each time. Which does not last work time.

Sports goggles, especially winter sports goggles, are manufactured for internal condensate reduction with double-walled, cold-insulating lenses. But even this works in many cases, despite special coating in the cold or humid air not really good. In addition, in winter sports glasses still has the additional disadvantage that the large lenses through thawing snow and again freezing water or freezing condensate, quickly blend fields by hoop, water drops or ice, get lubricating surfaces and optically refractive, distorting streaks. At full speed, without the possibility of cleaning, this can lead to an increased safety risk up to the risk of accidents.

The eyewear invented here pursues a different overall concept in the functional form, which combines several features that are of great advantage in certain situations. The glasses are despite their nature suitable for everyday use and also achieves a fundamentally different overall effect in their wearing properties. In addition to the ergonomically functional purpose optimization, a unique selling point for aesthetic and fashionable variants and lower forms is also opened up.

It is an object of this invention to define a pair of spectacles which has better aerodynamic properties, which sits more securely on the head, better enveloping the eyes, which is less susceptible to soiling, splashing water and condensate, which in most cases is more comfortable is to wear and which also gives a, novel, organically merging look and overall appearance of glasses and head or wearer of glasses.

The object of the invention is achieved in terms of aerodynamics, in which the lenses in radial centering are more strongly arched around the eyeball and drop-shaped circumferential edges lying in the eye sockets, closely adapted to the face shape and the skin around the edges of the eyes. The spectacle edges taper towards the corners of the eyes below the outer eyebrow ends, towards the cross-section of a circumferential retaining ring. The outer spectacle lens tip is also at the level of the upper ear attachment. Due to the noiseless surface with flowing envelope, wind currents can slide uninterrupted, without tugging on the glasses, without turbulence behind the glasses and without tearing in the eyes, ensure a secure grip and better visibility even in windstorm or strong wind.

The better grip of the glasses on the head, is achieved in that at the tapered end of the teardrop shape of a spectacle lens a resilient retaining half ring is mounted, which in the horizontal plane, above the ear around the entire back of the head, to the pointed approach of the lens on the goes through another page. The retaining ring exerts a slight spring force, which pushes the lenses towards the root of the nose with slight tension in the eye sockets. In general, the retaining ring disappears under the head hair, which simultaneously presses the retaining ring on the ear and the neck approach. Down the half-ring can not slip, as it, like conventional eyeglass temple, rests on the ear, but without pressing from behind against the auricle. In the face, the two lenses sit deepened in the eye sockets, whereby they can escape either down over the cheeks, still above the eyelids still to the side, from where they are held by spring force. To settle the eyeglasses are gripped at the base of the hoop ring, spread outwards, against the spring action and taken away or upwards away from the head. Placing is done in reverse order, with the glasses is either inserted under the hairline running horizontally over the ear or the covered covering hair is pulled out after covering the glasses.

The comfortable fit of the glasses is achieved by distributing the weight of the lenses over the entire edge of the glass, which causes no pressure concentrations, as with normal glasses on the nose saddle and in that there are no earloop behind the ears, the lateral concerns of the head, z. B. during sleep when traveling, bending or slipping after the glasses can be uncomfortable. The spring pressure of the retaining ring is designed so that on the one hand, a secure fit and on the other hand a lighter, evenly distributed and pleasant perceived holding pressure gives a comfortable ride.

The better protective effect, both in terms of splinter protection, as well as in terms of UV and light protection results from the all around the eye completely enclosing drop shape with all around tight-fitting rim, without a gap to the facial skin.

The susceptibility to spatter is reduced by the reduced spectacle lens surface. In addition, snow drops and raindrops from the excessive center of vision are more likely to rain faster on the stronger curvature when there is a headwind or wind. Also, water droplets can not be swirled by wind suction on the back of the lens and stay there looking wabernd.

The tendency to fogging is already reduced due to size and shape, since the glasses only the not so strong sweating eyelids and minimal cheek skin surfaces are covered. In addition, the lens rim is adapted to the respective use. Depending on the application, partial edge widening, small peripheral recesses, small air or drainage holes, fine or coarsely porous, skin-friendly leather, textile or foam strips or fine mesh-shaped spacer strips are mounted along the overlying edge.

The low-priced production as protective or sunglasses takes place in one piece in prefabricated clothing sizes with general accuracy of fit, without visual correction by optical lens action ( 2 ).

The high quality versions ( 1 ) are either made of plastic with surface coatings, removal and / or mirroring from the field of ophthalmic optics, in one piece and / or as composite material solutions spring steel strap ( 3 ) and glass or plastic lenses ( 1 ). With or without plug connection and with or without hinge for space-saving folding. The material transition ( 2 ) from lens to ring hoop is visibly or invisibly adjusted in different production techniques.

Protective, sports and sunglasses can be made with optically neutral eyeshades, which can alternatively meet visual aid requirements, in which the field of view and view center in the eyeglass with the required refraction is concave or convex produced during manufacture or in the behind an optically neutral eyeshadow in Field of view, a correction lens made of optically tempered plastic or glass is used. The total curvature depends on the required, free air space for the blink of an eye. Even better hold is caused by bending the ring hoop under the back of the head ( 3 ).

Applications are possible with all eyeglasses with 2 eyeglasses, such as visual aid eyeglasses with optical vision correction, sunglasses, goggles, sports glasses, fashion eyewear, etc ..
