Description

DESCRIPTION

A VISUAL FIELD EXPANDER OPTICAL EYEGLASSES SYSTEM

Technical Field

This invention relates to a visual field expander optical eyeglasses system which is used for rehabilitation of the eye diseases such as glaucoma, retinitis pigmentosa, diabetic retinopathy, optic neuropathy which have peripheral visual field defect or tunnel visual field and which provides fitting the image forming in the retina into a narrow visual field by minimizing and angling.

Prior Art

Eye diseases leading to peripheral visual field defect or tunnel are principally glaucoma, retinitis pigmentosa, diabetic retinopathy and optic neuropathy. Patients with said eye diseases often bump into surroundings, cannot go down the stairs or often fall and be subjected to physical injuries. In crowded places they might bump into others and be subjected to insults, criminal and psychological traumas like being accused with abuse. Their physical appearance is mostly normal; however, they are anxious patients who do not want to use a stick or visual impairment assistive device due to their anxiety for being understood as a patient with visual impairment and ostracization from the society. In the current state, patients are using stick or various visual impairment assistance devices.

In the present state of the art, there is a reverse telescope system that can be applied to one eye or both eyes. It is in the form of a binocular and it is hard to fit the optical axis into the narrow visual field, if optical axis is not centralized exactly, there might be distortions in the sight. It can expand the visual field only by minimizing the objects, it does not have a prismatic affect Since they are obvious as a visual impairment assistive device, most of the patients do not want to use them in social environments. At the same time their cost is very high. On the other hand, the visual field can be expanded with strabismus glasses prisms or Fresnel prisms. However, high dioptric prisms mostly impair central vision and decrease contrast sensitivity. Mostly current prism diopter is not sufficient to expand the visual field as much as the patient needs. High dioptric prisms applied to both eyes might lead to diplopia. The image forming in the prisms and the objects are not in their actual spatial positions, they can limit the spatial perception and activity capability of the patient.

In another method, glasses with digital LED screen are used. The image captured with a high-resolution digital camera is transferred to the screen in front of the eyes. The objects can be minimized or maximized at desired ratios and their contrast can be adjusted, these glasses can provide virtual digital image instead of real optical image. It is a big virtual system which is obvious that there is visual impairment assistive device in front of the eye. It is necessary to control with remote control and the cables. With these glasses, it is pretty hard to walk. It requires electrical connection and charge. Using ft requires a learning and adaptation curve. They are high technological products which are rather expensive and which require technical maintenance and repair. They can be easily damaged during their use by the patients with visual impairment Most of the patients do not want to use them in social environments.

Another method is named as an eyeglasses system the refractivity of which can be changed by administering silicone within adjustable dioptrics. However, said eyeglasses system does not change the image size and it does not have any expanding effect for visual field. It has the characteristic of prescription glasses only for far-near vision. Besides, it is used in the treatment of eye closing treatment for amblyopic patients.

The visual field expanding optical eyeglasses system used in the present invention consists of three-layered structure having a dioptrics and a different refractory index from front to back. The refractive indices of said three-layers are different from each other and from the refractive indices of fed eye lens. By gradually refracting fee light by said three-layers, the image that will form in the retina is minimized and the visual field is expanded. There is an optical chamber and an optical framework that surround the liquid and gas in an impermeable manner on the anterior refractive aspheric optical surface, on the posterior aspheric optical surface and within fee space therebetween. Between the anterior and posterior refractive optical surface, there is an angle of four- prism diopter the base of which tapers from bottom to top. This angle is designed to facilitate walking, going down the stairs and to expand the visual field of the patient by angling, especially in the defects of fee low half visual field. This prism angle and base layout can be provided by being changed according to the needs of fee patient. The Objects of the Invention

The object of this invention is to realize a visual field expander optical eyeglasses system which can expand the visual field significantly in cases which restrict the daily activity capability in the diseases which proceed with visual field stenosis.

Another object of the invention is to realize a visual field expander optica! eyeglasses system which provides activity capability without the need of sticks or visual devices with navigation system in the cases of visual field stenosis which restrict daily activity capability.

Another object of the invention is to realize a visual field expander optical eyeglasses system which prevents or minimizes the patient from experiencing a physical trauma while the patient is doing his daily activities in the cases of visual field stenosis which restrict daily motion capability.

Another object of tills invention is to realize a visual field expander optical eyeglasses system which is aesthetic and looks like normal eyeglasses instead of visual impairment assistive devices which the patient cannot use due to aesthetic needs and social drawbacks.

Summary of the invention

A visual field expander optical eyeglasses system defined in the first claim and in the other claims depended thereon for realizing the object of this invention consists of a frame, an optical glass, a coupling latch, a magnetic element and an optical system. The optical eyeglass system can be produced from aspheric mineral glass, acrylic or any other optical material. It can be worn as a visual field expander eyeglass by mounting on an eyeglass frame produced from any material. The large-angle optical system can be used by being mounted to right-left clips system via being attached in front of the prescription glasses of the patient, if any. The optical eyeglasses system is produced as a magnetic front apparatus and can be attached and detached to/from the eyeglasses frame by magnets after the prescription numbers of the patient if any, are mounted on a magnetic frame. In the optical system, an anterior refractive surface is placed on the posterior refractive surface with the posterior refractive surface being located at its base. There is a refractive chamber between the anterior and posterior refractive surface. The anterior refractive surface, the posterior refractive surface and the refractive chamber found within the structure of the optical system have different refractive indices. Between the posterior refractive surface and the anterior refractive surface, there is ah angle of four-prism diopter with their base being at the bottom. This angle is designed to facilitate walking, going down the stairs and to expand the visual field of the patient by angling, especially in the defects of low half visual field. This prism angle and base layout can be provided by being changed according to the needs of the patient There is a refractive chamber between the anterior refractive surface and the posterior refractive surface. The lights reflecting ova- the object whose image will form in the eye are primarily refracted over the anterior refractive surface. The light passing into anterior refractive surface refracts towards the posterior refractive surface via fluid and gas having different refractive indices located in the tight refractive chamber. Finally, a refraction occurs from the posterior refractive surface such that a minimized image will form in the retina. Thus, it becomes possible to create the visual field by expanding the visual field which the eye can see via the optical eyeglasses system. The type of the fluid and gas to be contained in the refractive chamber is determined according to the required refractive index. In the cases where the refractive index is demanded to be high, silicone and liquid perfluorocarbon or any optical transparent liquid can be used. In the cases where refractive index is demanded to be low, C3F8, SF6, C2F5 or any optical gas can be used.
