FIELD OF THE INVENTION
The present invention relates to an accessory for working with displays,
computer monitor screens, TV-sets and other electronic devices.
BACKGROUND OF THE INVENTION
From the background of the invention an accessory is known for blocking
the field of vision of eyes, comprising a system for fixing it to the head of a
user, made in the shape of a spectacles rim, and a member for blocking one of the
eyes (US 4582401A, Cl. G02C 7/16, 1986). Field of using this accessory is limited
by squint correction.
Also a personal accessory is known for working with the screen of
a computer display, comprising a system for fixing it to the head of a user, made
in the shape of a spectacles rim, connected to a device for releasing the tension
of the eye muscles, made in the shape of an optical protective filter, covering
the surface of glasses lens (RU 2005314 Cl, Cl. G02B 5/20, 1993).
The last accessory is chosen as the nearest analogue of the invention.
Despite the fact, that the known accessory as well as the proposed one is aimed
at increasing the working capacity of the user, working with the screen of an electronic
device owing to decreasing of the fatigue of his eyes, the known accessory does
not provide relaxing the weakening muscles of both eyes.
SUMMARY OF THE PRESENT INVENTION
The technical result of the invention consists in increasing the efficiency
and the duration of the user's working with the screens of the abovementioned devices
owing to relaxing the weakening muscles of both eyes and also in making it easy
to manufacture and to use and also in reducing its cost significantly.
The summary of the invention consists in the fact, that as well as
in the nearest analogue, the personal accessory for working with the screen of
an electronic device comprises a system for fixing it to the head of a user, connected
to a device for releasing the tension of the eyes, but in contradistinction to
the nearest analogue, the device for releasing the tension of the eyes is made
in the shape of at least one member for blocking the field of vision of the eyes,
which provides the possibility of blocking sequentially the user's left and right
eyes. The said member may be made in the shape of a flap or a shield, made of light
absorbing and/or scattering material.
The accessory is characterized also with that the system for fixing
it to the head of a user may be made in the shape of an elastic bandage, a hoop,
a helmet or a spectacles rim. In the case of a rigid system for fixing to the head
of a user, at least one sheild may be joint with it by means of a hinge.
When the user looks with both eyes, he receives a volumetric image,
which permits to orient oneself and to act easier in the surrounding.
Texts and drawings on the paper, images on the display, monitor screen,
TV-set are plane by their physical nature. Even if an illusion of a volume is created
with the help of various methods (perspective, color effects etc.), it is not connected
with the perception with two eyes, these effects remain during perception with
Therefore the process of reading, writing, working and leisure with
the help of a display, monitor of TV-set by means of one eye is possible and sufficient.
The advantage of the invention consists in following: the weakening
muscles of the eyes, which are usually tensed, while blocking the field of vision
of one of the eyes relax, the tension created in the eyes is taken off, and the
user becomes capable to work longer and more effectively without fatigue and ache
in the eyes.
BRIEF DESCRIPTION OF THE DRAWING FIGURES
The accessory is explained by the drawings, in which:
The examples shown on the drawings do not limit the variety of the embodiments of
the accessory, but they are picked out as the most acceptable from the point of
simplicity and low cost of manufacturing of this accessory. 'The accessory comprises
the system for fixing it to the head of a user, made, for example, in the shape
of an elastic bandage 1 (fig. 1), a hoop 2 (fig. 2), a helmet 3 (fig. 3) or a spectacles
rim 4 (fig. 4). Several or at least one opaque flap or shield 5 is joint with the
said system for fixing the accessory to the head of a user, said flap or shield
5 is made of light absorbing and/or scattering material and is joint, for example,
with the spectacles rim 4 by means of a hinge.
- Figure 1 is an embodiment of the system for fixing the accessory to the head
of a user in the shape of a bandage;
- Figure 2 ― the same in the shape of a hoop;
- Figure 3 ― the same in the shape of a helmet;
- Figure 4 ― the same in the shape of a spectacles rim;
- Figure 5 is the accessory, fixed to the head of a user.
The system for fixing to the head of a user may be made of a fabric,
resilient elastic band or rigid material in the embodiments of a hoop, a helmet
or a spectacles rim. Such material may be plastic or light metal, for example,
aluminum alloys. The shield or the flap may be also made of different materials,
impeding the eye to see the image on the monitor screen. Such materials may be:
plastic, glass, cartoon, fabric, wood, organic glass etc. Flap made of a soft material,
for example, fabric is flexible, which is convenient in using. Also it is possible
to combinative rigid and elastic materials for making the system for fixing the
accessory to the head of a user, as it is shown on the fig. 5, where the front
part of the said system is made of rigid transparent plastic, connected to an elastic
resilient band, located at the back of the head and facilitating putting on and
taking off of the accessory, and its fixing to the head of a user.
DESCRIPTION OF PREFERRED EMBODIMENTS
The accessory is used in a following way: for example an elastic bandage
1 is fixed to the head of a user, a flap or a shield 5 for blocking one of the
eyes is mounted opposite an eye and the user begins working with one of abovementioned
devices, percepting an image with the other eye. On the expiry of a certain period
(individual for each user) the elastic bandage 1 is replaced so that the field
of vision of the other eye is blocked, and the first eye begins to percept the
image, then the process repeats.
Worth mentioning that at present such electronic devices as computers,
TV games and others, equipped with displays, have become widely spread both in
business sphere and at home, including among children and teenagers, and because
of this fact making it easy to work with such devices and increasing the efficiency
of this work have become a vital necessity.
This accessory permits to increase in several times the duration of
reading the text, percepting the image on a display, a screen of a monitor, TV-set
and others electronic devices without eyes fatigue because it provides releasing
the tension of the weakening mussels of both eyes, which is one of the main causes
of the fatigue of users, working with computers and other devices.
