Description
The utility model relates to a kind of glasses, particularly relates to a kind of split visual area glasses with different vision areas.
At present, the glasses that people often wear mainly contain two types: a kind of is the most general single focus glasses, that is the eyeglass of glasses has only a focus, no matter the people of wearing spectacles watches far and near scenery to focus on a focus, so no matter for myopia or farsighted person, in use inconvenience is arranged all, because no matter be myopia or long sight, watching at a distance or all needing the different focal length of conversion nearby the time, obviously traditional single focus glasses can not meet the demands simultaneously, the inconvenience part is arranged in actual use, need wear spectacles when watching distant place scenery as the myopia patient, but, when reading newspaper, wear spectacles for a long time and can think that eye muscle aches as reading at the thing of seeing nearby; Farsightedness patient watches that at a distance scenery then can be smudgy wearing spectacles for long sight, thereby needs to remove down glasses or change glasses.In order to overcome the inconvenience that single focus glasses bring, another kind of multifocal spectacles has structurally been made improvement, as the disclosed a kind of glasses of european patent application instructions EP-273-650-A, this glasses process a different district of focus in the bottom of eyeglass, the user is in the lens region of watching at a distance and use respectively nearby the time upper and lower different focal, this glasses can satisfy the requirement according to the range conversion focal length, but this glasses manufacturing technique requirent is higher, manufacture difficulty is big, thereby cost is higher.
The purpose of this utility model is to overcome the shortcoming of prior art, and the split visual area spectacles that provide a kind of suitable A nearsighted person to use utilize the utility model can watch far and near scenery easily, uses the eyes can be tired for a long time.
The split visual area spectacles for long sight that the purpose of this utility model also is to provide a kind of suitable farsighted person to use utilize this glasses to make things convenient for and clearly watch far and near scenery, use the eyes can be tired for a long time.
Existing glasses are made of mirror leg, picture frame, concave lens, nose holder, and the utility model mainly improves size, position and the shape of eyeglass.
The utility model is realized by following technical proposals: the split visual area spectacles are made of mirror leg, picture frame, concave lens, nose holder, picture frame is identical with the picture frame of general single focus glasses, the height of concave lens is 55%～60% of general single focus eyeglass height, the base of concave lens is made into horizontal straight flange, make two eyeglass bases on video, fully overlap and do not influence the effect of watching, concave lens is installed in the top of picture frame so that the A nearsighted person when sight line is overlooked by eyeglass when looking squarely sight line do not pass through eyeglass.
The split visual area spectacles for long sight are made of mirror leg, picture frame, hyperopic lens, nose holder, picture frame is identical with the picture frame of general single focus glasses, the height of hyperopic lens is 55%～60% of general single focus eyeglass height, the top of hyperopic lens is made into horizontal straight flange, make two eyeglass tops on video, fully overlap and do not influence the effect of watching, hyperopic lens is installed in the bottom of picture frame, and sight line was not passed through eyeglass when sight line was not overlooked by eyeglass when the farsighted person was looked squarely.
As further being improved to of split visual area spectacles: the picture frame height is 55%～60% of general single focus eye glass frame height, the bottom of picture frame is a straight flange, make two picture frame limits on video, fully overlap and do not influence the effect of watching, the edge of concave lens and picture frame periphery fit like a glove, the nose holder according to spectacles wear the position when installing that sight line is overlooked by eyeglass when guaranteeing to look squarely after the A nearsighted person wears sight line do not pass through eyeglass.This form is more attractive in appearance, does not influence result of use.
The utility model is compared with general single focus glasses advantage easy to use, can satisfy simultaneously and clearly watch at a distance and the requirement of scene nearby; Compare with existing multifocal spectacles, because of it highly only is 55%～60% of existing eyeglass, thus obviously weight reduction, and the also corresponding reduction of cost, simultaneously because it is simple in structure, so processing is more convenient, can be in general optician's shop processing.
