Description

Multifunctional wearable visual evaluation device integrating image display and image capture

The present invention provides a multifunctional wearable visual evaluation device integrating image display and image capture, especially a wearable device that can be used in a visual detection mode by configuring a display device, an optical unit, and an image capture device. , while the display device is displayed to perform detection, the image capture device can still capture the image synchronously towards the viewing position through the optical unit, so that the image capture by the image capture device is not affected by the configuration of the display device And shielding, in order to carry out visual inspection and shoot eyeball images at the same time, in order to facilitate the perfect inspection of the user's eyes.

By the way, with the rapid development of science and technology, people's dependence on 3C products is increasing day by day, and the incidence of eye diseases is also increasing year by year. Most eye diseases are difficult to fully recover after the onset, and can only be detected and treated early to improve complete cure. Chance.

At present, most of the eye examinations in the society are usually carried out with the help of professional doctors and equipment in the hospital. For example, the existing professional eye examinations use the WAM700 pre-guided wave aberration analysis multifunctional screening instrument to measure the degree. , corneal curvature, thickness detection, leading wave aberration analysis, etc., for professional eye detection; most eye measurement instruments are very large, cannot be easily moved, and are expensive. The hospital completes the examination, and the life of modern people The accelerated pace of life, coupled with the time-consuming and inconvenient inspection process, and the need to arrange another time for queuing and registration for inspections, has led to a decline in the enthusiasm of many people for eye inspections, which also indirectly reduces the possibility of early detection of recessive eye diseases However, based on the concept of early detection and early treatment, it is still necessary to carry out regular testing in order to help early detection of symptoms and improve the cure rate.

The common eye diseases and corresponding examination methods are summarized as follows:

1. Glaucoma is a common eye disease that threatens the optic nerve and visual function. It is known as the "invisible killer of vision". Because it has almost no symptoms in the early stage, it is undetectable, so it is the most blinding eye disease in the world. It ranks first, and its only treatment method is early detection and early intervention, so as to delay or even stop the further loss of vision through drugs or surgery; and the examination of glaucoma is mainly to check the visual field of the eyes separately to judge whether it is glaucoma. There are cases of visual field defects to facilitate the diagnosis of glaucoma, and because of the complementarity of binocular vision, the detection system needs to be tested separately, which requires a large visual field testing instrument to carry out, and a single test costs a lot time, thus reducing the willingness of patients to undergo testing.

2. Macular degeneration, also known as age-related macular degeneration, is a lesion in the macular area. The macula is located in the center of the retina directly behind the eyeball. The sensory cells of the retina are the densest and the most important visual center. It is the most important of the retina. The part of the retina is also the most sensitive area of visual function. The retina is like a camera film in the eye. Once the disease occurs, the vision will be greatly affected. Macular degeneration is a common eye disease over the age of 50. Caused by functional aging and decline; macular degeneration can be divided into dry macular degeneration and wet macular degeneration, which must be judged by physicians based on different macular pathological changes; modern people use 3C products for a long time and overuse their eyes Under stimulating conditions, the eyes will age prematurely, so it is not uncommon for young people to have macular degeneration; most patients with macular degeneration have obvious subjective symptoms, including metamorphopsia, color fading or dark shadows, vision loss, visual acuity, etc. Round, oval, oval, and irregular dark spots appear in the field, and the objects seen appear distorted, deformed, or have abnormal color perception, and sometimes cause a decrease in contrast color sensitivity. If not treated immediately, it may eventually lead to Blindness; and these symptoms can be detected and treated early by combining visual acuity tests, visual field tests, color vision tests, and contrast tests.

3. Cataract, which is a disease that causes vision loss due to turbidity of the lens of the eye, and may invade one or both eyes; cataract is that the originally transparent and clear crystalline lens in the eye becomes turbid, and protein agglomerates or yellow-brown pigments deposited in the crystalline lens cause the crystalline The transparency of the retina is reduced, which in turn reduces the light sensed by the retina and blocks the line of sight, resulting in visual impairment. It is a disease caused by lens opacity. It can usually be divided into two types: congenital and acquired. Among them, acquired senile cataract is Most common; cataracts can lead to driving difficulties, dyslexia, and reduced ability to recognize people; vision loss can also lead to risks of falls and depression; in addition, cataracts are the cause of half of blindness and 33% of visually impaired cases worldwide, approximately 2000 people worldwide Tens of thousands of people are blind due to cataracts; the most common cause of the lesion is aging, and other causes include trauma, radiation exposure, congenital, complications after eye surgery, etc.; symptoms include decreased chroma, blurred vision, and light produced by light sources. Halos, photophobia, and visual disturbance in dark environments; diagnostic methods include visual acuity examination, astigmatism examination, and color vision examination.

From the above, it is obvious that the detection of eye diseases is really important, but limited by the cost, volume and detection time of detection equipment, it will make it difficult to effectively popularize eye detection and reduce the enthusiasm of eye detection. It also indirectly reduces the cure rate when suffering from eye diseases. Therefore, if a portable, low-cost rapid detection instrument can be developed so that ordinary people can easily use it without professional training, it will help its popularization. Therefore, its detection products The development of it is one of the problems that need to be solved urgently.

Among the existing head-mounted eye-related inspection or auxiliary devices, it is known to provide a "near-eye display and imaging head-mounted device" similar to my country's invention patent certificate No. I727511.

It is also known that there is another "binocular split vision cognitive operation simulation system" similar to my country's new patent certificate No. M615221, which is mainly configured in the user's left and right eyes through the first lens and the second lens. It is used to train the concentration and recognition ability of the user's binocular separation by receiving different information from the two eyes; although its configuration is also to present the display information through the lens, as mentioned above, it is mainly used for The training and testing of the focus of recognition is not exclusively used for the detection of various eye diseases.

Xizhi also provides an invention patent case similar to my country Publication No. 201917447 "head-mounted display device and color difference enhancement method", which is mainly through the configuration of a display on the head-mounted display device. Display system and image capture system, and capture the front and surrounding images through the image capture system, strengthen the image through color difference, and present it to the user through the display system; and its configuration is mainly used to solve the problem of improving color for people with color weakness Difficulties in identification are not used for the detection of actors, and the image capture system is mainly used to capture environmental images, not for detection of the user's eyes.
