Description

  The present invention relates to single-eye semi-shielding glasses for double vision patients.

Conventionally, in order to correct double vision, a shielding film seal is known which is applied in the form of a seal on the back side of a spectacle lens to semi-shield the lens (transparent OCCLUSION of Ryser Optik (Switzerland)). By semi-shielding the lens on the eye movement impaired side with this shielding film seal, the symptom of double vision that an object looks double is improved. The shielding film seal has 10 levels of transmittance, and can be selected according to the patient's preference.

Is covered, and double vision does not occur in peripheral vision.

  Hereinafter, an embodiment of single-eye semi-shielding glasses for double vision patients according to the present invention will be described with reference to the accompanying drawings.

  In FIG. 1 showing the one-eye semi-shielding glasses for double vision patients of the present embodiment, 1 is a frame, and two lenses 2 and 3 are fixed to the frame 1. A translucent plate 4 having the same shape as the lens 3 is fixed to the frame 1 together with the lens 3 on the back side of the one lens 3, so that the translucent plate 4 is not easily detached from the frame 1. The translucent plate 4 is formed to be translucent by forming fine irregularities on at least one surface. The translucent plate 4 is provided only on the lens 3 in order to semi-shield the eye on the side having an obstacle, and is not provided on the lens 2.

  The frame 1 is made of plastic and can be easily processed when the translucent plate 4 is fixed. Since the translucent plate 4 is made of polypropylene and the polypropylene is lightweight, the translucent plate 4 hardly affects the weight balance of the glasses. Also, since polypropylene is easy to process, the translucent plate 4 can be easily processed according to the shape of the frame 1, and once the translucent plate 4 is fixed to the frame 1, it is difficult to come off. Furthermore, since the translucent plate 4 is made of polypropylene, processing of screw holes and the like is easy.

  The lens 2 and the lens 3 are slightly colored to the same extent so that the lens 3 is not conspicuously provided with the translucent plate 4. Further, the lens 2 may have a degree as required. Furthermore, since the translucent plate 4 is fixed to the back side of the lens 3 and the front side of the lens 2 and the lens 3 has the same gloss, it is not noticeable that the lens 3 includes the translucent plate 4. ing.

  The length H in the vertical direction of the lenses 2 and 3 is 80% or more of the length L in the horizontal direction, so that the periphery of the eye is covered over a wide range.

  The single-eye semi-shielding glasses for double vision patients of this embodiment have good light transmission from the outside toward the patient, the eyelids on the back surface of the lens 3 and the state of the eyeball are well observed from the outside, and special glasses are worn. There is very little discomfort. On the other hand, from the patient side, the visual field is well blocked in a wide range, and the double vision symptom that the object looks double is solved.

  Although the fundamental treatment for double vision is eye muscle surgery, it cannot be performed in patients with complex eye movement disorders or systemic disorders. In addition, there are many patients who do not wish to have surgery because surgery involves pain. As a symptomatic treatment for such diplopia to the patient, it is extremely effective to use the single-eye half-shielding glasses for double vision patients of the present invention in order to shield the visual field without impairing the appearance on the eye movement disorder side.

  As described above, according to the one-eye half-shielding glasses for double vision patients of the present embodiment, the half of the lens 3 is the same shape as the lens 3 on the back side of the lens 3 and is fixed to the frame 1 together with the lens 3. By providing the transparent plate 4, the translucent plate 4 is difficult to come off from the frame 1.

  Since the translucent plate 4 is made of polypropylene, the translucent plate 4 hardly affects the weight balance of the glasses because polypropylene is lightweight. Further, since polypropylene is easy to process, the translucent plate 4 can be easily processed according to the shape of the frame 1 and is difficult to come off once the translucent plate 4 is fixed to the frame.

  Further, since the frame 1 is made of plastic, processing for fixing the translucent plate 4 is facilitated.

  Further, since the lens 3 is colored to the same extent as the other lens 2, it is not conspicuous that the one lens 3 is provided with the translucent plate 4, and the appearance is improved.

  Furthermore, when the length H of the lens 3 in the vertical direction is 80% or more of the length L in the horizontal direction, the periphery of the eye is covered in a wide range, and double vision does not occur in peripheral vision.

  The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, the case where the translucent plate is made of polypropylene has been described as an example. However, the present invention is not limited to this, and the translucent plate may be made of other synthetic resin or glass. Further, the frame may not be made of plastic and may be formed of metal.

  The effect of the single-eye half-shielding glasses for double vision patients of the present invention was confirmed in actual cases. In this case, diplopia was strong in the downward view, causing a lot of obstacles such as falls during walking. There were various diseases in the elderly, and there was no indication for surgery. By wearing the single-eye half-shielding glasses for double vision patients according to the present invention, even when looking downward while walking, double vision was not noticed, and cosmetically, there was no sense of incongruity when viewed from others.

It is a front view which shows one Example of the single eye semi-shielding spectacles for double vision patients of this invention.
