Teo.h.n i o.a l F i e l d

The present invention relates to spectacles for the aged fitted halves lens in its rim that inner spaces for fitting lens in the conventional rim for spectacles are divided into the upper half space and the lower half space, in any one of both spaces halves lens for spectacles are fitted and the remaining halves spaces are left as they are, i.e. empty space. The spectacles of the present invention are to complement weak eyesight of presbyopias by means of putting on it because a wearer can take a look optionally through either the fitted lens or empty space left in the rim of the spectacles.

Background Art

Since the crystaline lenses of human's eyes are aged relative to advancing in age, its elasticity and reflactive index are reduced, thus the focal distance thereof according to far and near is not regulated harmoniously and as a result the eyes result in presbyopia.

In case of presbyopia which can have a good look objects of far distance, it cannot take a good look that of near distance, while in case of presbyopia which can have a good look at that of near distance, it cannot take a good look at that of far distance.

For resolution of such a problem development of various type of spectacles for the aged have been attempted. However their wearer put on it only in necessary case and then had to take off it in case of unnecessary.

Therefore their wearers felt inconvenience.

When behind the inner surface of conventional spectacles a magnifier is put to see through them, their application is not only well but also the wearer should always carry the magnifier together with spectacles during going out.

Therefore, the separate magnifier causes the weares inconvenience to use it.

In addition, in case that lower part of lens of spectacles is made in the form of a magnifier, a wears can take a look objects of far distance by means of conventional upper part of the spectacles lens and can take a look an object of near distance by means of the lower magnifiers thereof. However in this case, as the wear should take a look at, through conventional lens, far distance capable of seeing with eyes directly, probably the visibility will be reduced. Accordingly eyes of the wearer can be fatigued easily.

Furthermore, said conventional spectacles have defect which if on the surface of lens layers of frost are formed by means of sudden change of temperature in winter, it loses its function as spectacles.

Disclosure of Invention

It is an objection of the present invention that it is to provide spectacles for the aged which can take a look objects clearly not to mention of far or near distance, can be used conveniencely and can prevent fatigue of eyes.

The present invention relates to spectacles for the aged characterized in that inner spaces of rims of the glasses are divided into upper spaces and lower spaces by forming projections for hanging lens on inner side of rims corresponding to the phantom diving lines of said inner spaces, in any one side spaces of said divided upper and lower spaces in the rim halves lenses corresponding to the spaces thereof are fitted, the remaining halves spaces of other side are left as they are, i.e. as empty spaces. if humans having presbyopias which can take a look well far distance but cannot take a look well near distance intend to use the spectacles of the present invention, convex lenses are fitted in the lower spaces thereof so as to see well near distance, and on the contrary if humans having presbyosias which

can take a look well near distance but cannot take a look well far distance intend to use the spectacles of the present invention, concave lenses are fitted in the upper of the spectacles so as to see well far distance. Said spectacles of the present invention have a merit capable of seeing objects clearly not to mention of far or near distance proventing fatigue of eyes and resolving inconvience problems caused by lens.

Mode fo ' Carrying out tlτιe Invention

Now referring to accompanying drawings the present invention will be described in detail below.

In conventional rims 1 of spectacles, inner spaces 2,2' for fitting lens of said rims 1 are divided into the upper spaces and the lower spaces by means of forming projections 6,6' for hanging lens on inner side of rims positioned in the phantom dividing lines of said spaces 2,2' and in only any one side spcaes of said upper and lower spaces a half lenses corresponding to the spaces are fitted, the remaining other empty space are left as they are, i.e. as the empty spaces 4,4'.

Referring to Figure 1, in the lower spaces of said inner spaces 2,2' for fitting lens halves magnifiers 3,3' of type corresponding to the spaces are fitted, the upper spaces of said inner spaces 2,2' are left as the empty spaces 4,4'.

Referring to Figure 3, in the upper spaces of said inner

spaces 2,2' for fitting lens halves concave lens 5,5' of type corresponding to the spaces are fitted, the lower spaces thereof are left as the empty spaces 4,4'.

Since a rim(frame) 1 of the spectacles for the aged of the present invention described above is identical to that of the conventional spectacles, it can be manufactured easily and also the spectacles of the present invention can be always weared by the humans having presbyopias without, repeats of putting on and taking off them as in conventional magnifier. If humans having presbyopias which can take a look well far distance but cannot take a look well near distance intends to use the spectacles of the present invention, by wearing spectacles for the aged as shown in Figure 1, which halves magnifiers 3,3' are fitted only in the lower space and the empty spaces 4,4' are formed in the upper spaces, as shown in Figure 2 the wearer can see clearly objects such as a tree 9 of far distance through the empty spaces without lens so that fatigue of eyes can be reduced, also when he wishes to see objects of near distance such as a book 10 or a newspaper he can see clearly and easily through the lower magnifier 3 without taking off spectacles.

While in case humans having a presbyopia can take a look well near distance but cannot take a look well far distance, by wearing spectacles for the aged as shown in Figure 3, which halves concave lenses 5,5' are fitted only in the upper space and in the lower space the empty spaces 4,4' are formed, as shown in Figure 4 the far distance can be taken a look through said concave lens 5 and the near distance can be taken a look clearly through the empty space 4, without fatigue of eyes and not to mention of far or near distance.

Furthermore, as spectacles of the present invention have the empty spaces 4,4' fatigue of eyes is reduced, the weares can see objects directly and clearly as discribed above as well as in the empty space 4,4' layers of frost cannot be formed in spite of sudden change of temperature in winter, although rain or

snow falls the wearer does not undergo inconvenience caused by humidity adhered on lens and also weight of the spectacles also can be reduced by fitting halves lens.

In addition, since in rims positioned in phantom dividing lines of spectacles of the present invention the projections 6,6' are formed, halves lenses 3,3' or 5,5' can be fitted fixedly in halves spaces of inner spaces 2,2' of the rims by said projections

6,6'.

Industrial Appl cability As the above-mentioned spectacles for the aged formed with halves lens of the present invention are made in the form identical to rims of conventional spectacles, a process for manufacturing it is not different from the conventional process and thus its manufacture is very easily. Furthermore, as the spectacles comprise the halves lens and the halves empty spaces, the users can wear always them and can take a look clearly objects as needed through said lens or the empty spaces without fatigue of eyes.
