Abstract
The invention provides a pair of bifocal glasses for the myopia, which solves the problem that the myopia with presbyopia can not see clearly the nearby/distant objects. The pair of glasses comprises a movable myopia lens frame and a fixed myopia lens frame, and is characterized in that the sum of degrees of the corresponding lenses mounted on movable myopia lens frame and the fixed myopia lens frame is just the degree of a normal glasses for the myopia; the lenses mounted on the fixed myopia lens frame are suitable for users to see the nearby objects; and the papillary distance between the two lenses on the movable myopia lens frame is equal to that between the two lenses on the fixed myopia lens frame. The bifocal glasses provided by the invention has the advantages of simple structure and convenience in operation, and the myopia with presbyopia can see clearly the nearby/distant objects without changing the glasses. Therefore, the pair of bifocal glasses has value.
Description
Technical field
The present invention relates to spectacles, especially the myopia bifocals.
Background technology
At present, people suffer from bathomorphic large contingent, and people can correct defects of vision through wearing spectacles.But increases along with suffering from the bathomorphic people age, presbyopia's phenomenon can appear in myopia patient, sees thing far away when wearing normal spectacles or on foot etc. does not have sense of discomfort, but do not see when seeing nearer object, as read newspaper, computer etc.At this moment as suitably the number of degrees that reduce spectacles just can be seen nearly thing clearly.Healthy usage is, must be when seeing nearly thing through doctor's inspection and the spectacles that mix the suitable number of degrees after detecting as the spectacles of watching nearly thing.Usually to join two pairs of glasses so the myopia patient of this presbyopia's phenomenon occurs, wear the spectacles of the normal number of degrees when not seeing nearly thing, wear the spectacles of watching nearly thing when seeing nearly thing.Because people's life often is in the state of alternately seeing nearly thing and thing far away, it is very inconvenient to change glasses like this.
Summary of the invention
The present invention occurs conveniently solving the myopia bifocals of watching far and near thing problem behind the presbyopia for the myopia patient.
The present invention is achieved in that the myopia bifocals; Form by near-sighted horse of activity and fixing near-sighted horse; It is characterized in that: movable near-sighted horse is each required normal spectacles number of degrees of user just in time with fixing the lens number of degrees stack of installing on the near-sighted horse, and the eyeglass that the user watches the spectacles number of degrees of nearly thing fixedly is installed on the horse.
Described myopia bifocals, between two eyeglasses of installing on the movable near-sighted horse with fixing near-sighted horse on interpupillary distance between two eyeglasses installed equate.
The present invention is simple in structure, and is easy to operate, makes the myopia patient glasses occur need not alternately changing behind the presbyopia and just can easily solve and watch far and near thing problem, has value.
Description of drawings
Nearly thing state uses synoptic diagram to Fig. 1 for the present invention watches.
Fig. 2 uses synoptic diagram for the common state of the present invention.
Fig. 3 is an another kind of form synoptic diagram of the present invention.
Embodiment
As shown in Figure 1, see nearly thing state for the myopia bifocals and use synoptic diagram.The eyeglass 101 of the myopia number of degrees of watching nearly thing is installed on the fixing near-sighted horse 1; The difference number of degrees myopia sheet 202 of the number of degrees of normally wearing spectacles and the spectacles number of degrees of watching nearly thing is installed on the movable near-sighted horse 2, and the eyeglass 101 of the myopia number of degrees adds up to the spectacles number of degrees when normally wearing with the number of degrees of difference number of degrees myopia sheet 202.Interpupillary distance between two eyeglasses of installing on movable near-sighted horse 2 and the fixing near-sighted horse 1 equates.For example: someone checks that through the doctor number of degrees left eye of normally wearing spectacles is-500 degree; Right eye is-575 degree, watches the number of degrees left eye of the spectacles of nearly thing to be-300 degree, and right eye is-350 degree; It is-300 degree that left eye is installed on the then fixing near-sighted horse 1; Right eye is the eyeglass of-350 degree, and it is-200 degree that left eye is installed on the movable near-sighted horse 2, and right eye is the eyeglass of-225 degree.Movable near-sighted horse 2 is connected through pivot 3 with fixing near-sighted horse 1, can be easily with the near-sighted horse 2 of hand rotation activity.As shown in Figure 1, the near-sighted horse 2 of activity is turned on the fixing near-sighted horse 1, then can watch nearly thing, be equivalent to wear one pair of spectacles of watching nearly thing.Just be equivalent in the above-mentioned example someone and worn one pair of left eye and be-300 degree, right eye be-350 spectacles of spending.
As shown in Figure 2, for the common state of myopia bifocals uses synoptic diagram.Forward the near-sighted horse 2 of activity to fixing near-sighted horse 1 front; Make eyeglass and the eyeglass stack of fixing on the near-sighted horse 1 on the movable near-sighted horse 2; Before and after the interpupillary distance between two eyeglasses of installing on movable near-sighted horse 2 and the fixing near-sighted horse 1 one to, then be equivalent to wear one pair of normal spectacles.Just be equivalent in the above-mentioned example someone and worn one pair of left eye and be-500 degree, right eye be-575 spectacles of spending.
The movable near-sighted horse 2 of myopia bifocals does not perhaps have frame according to moulding and the frame of having processed attractive in appearance.As shown in Figure 3, movable near-sighted horse 2 is processed the synoptic diagram of no frame.
Claims (2)
1. myopia bifocals; Form by near-sighted horse of activity and fixing near-sighted horse; It is characterized in that: movable near-sighted horse is each required normal spectacles number of degrees of user just in time with fixing the lens number of degrees stack of installing on the near-sighted horse, and the eyeglass that the user watches the spectacles number of degrees of nearly thing fixedly is installed on the horse.
2. myopia bifocals as claimed in claim 1 is characterized in that: between two eyeglasses of installing on the movable near-sighted horse with fixing near-sighted horse on interpupillary distance between two eyeglasses installed equate.
