Description

Wide-spectrum protective glasses suitable for oral medical personnel

Technical Field

The invention relates to the field of occupational disease protection of oral and oral medical personnel, in particular to a wide-spectrum protective glasses suitable for oral and oral medical personnel.

Background

With rapid development of oral medicine, minimally invasive and precise operation trends of dental treatment appear, which leads to high dependence on visual judgment. The concrete characteristics include: "extremely small objects" -details of the dental treatment even need to be effectively identified with the aid of magnifying glasses, microscopes, such as the root canal orifice of a root canal treatment, the margin of a tooth preparation, all with the aid of instruments to an accuracy of about 1/10 mm; the 'low contrast' -the components of enamel, dentin and the like of the tooth tissue are close, the color system is consistent, even the repairing filling body is attractive, and the tooth tissue is integrated with the natural tooth. The eyes of the patient move frequently, the patient needs to be highly concentrated in a local treatment area during operation, meanwhile, instruments need to be frequently replaced, the patient needs to raise the head and turn the neck, rotate the eyeballs and observe the conditions of the patient in the table, the brightness of the dental vision is different from the surrounding environment, and the eyeballs need to be adjusted due to frequent strong and weak light switching. The above development directions all mean that brighter illumination is needed for local illumination and room illumination, and only with brighter illumination, the efficiency can be improved and the treatment effect can be ensured.

The outer layer of the dental crown is enamel, the surface of the dental crown is a slight uneven smooth surface, incident light is easily reflected at various angles, glare is generated, the dental crown works intensively in a high-brightness visual field for a long time, and a large amount of glare easily causes eye fatigue and visual deterioration.

Meanwhile, more and more dental illuminations adopt the LED illumination technology: blue LEDs are used to mix yellow phosphor to create white light in the human eye, which illuminates the white light containing the higher energy peak of the blue electromagnetic waves. The blue light has short wavelength, potential damage is caused to eye tissues, excessive exposure of eyes to blue electromagnetic waves can cause red eyes, dry eyes, unsmooth eyes, blurred vision and fatigue, severe people cause vision reduction, and macular degeneration of eyeballs is caused. The main reasons are as follows: short wavelengths are more likely to scatter in the refractive medium than long wavelengths, and glare from scattering is the root cause of scintillation, glare, and dry eyes.

Further research shows that when excessive blue light penetrates through the dioptric medium to reach the retina, the formation of lipid peroxides and the generation of active oxygen radicals are induced, a series of chemical damages are generated on intracellular biological membranes, proteins and other cell molecules, the permeability of cell membranes is influenced, the cells lack nutrients, and therefore the damage, the apoptosis, the dissolution of the biological membranes and even the necrosis and the apoptosis of the cells are caused, and the eye diseases of the retina and macular region are caused, such as: retinal pigmentary degeneration, age-related macular degeneration and the like, severe patients can cause vision loss, and researches show that cell damage apoptosis can be an important mechanism of blue light to damage the retina.

Recently, the dental field has also attracted attention as a protection against oral occupational diseases by the phenomenon of fluorescence: teeth, particularly collagen fibers contained in dentin, absorb blue electromagnetic waves that have penetrated enamel, and generate green fluorescence, which is mixed with reflected light of the blue electromagnetic waves to cause a blue glare on the tooth surface. Such glare can also lead to eye fatigue and decreased vision.

In addition, the colors of teeth and related diseased tissue observed by the human eye in oral treatment under normal daylight illumination contain little blue or green color. The tooth color is generally recognized as yellow and light yellow; caries: light brown, chalky, black; dental calculus: brown, yellow, black, magenta, white. The gum is pink in color and shows a deep dark red color if the gum is engorged with edema. If analyzed by Lab of the International Lighting Association, the color system is mainly located in: red + a and yellow + b; in clinical observations, blue-b, and green-a were rarely used.

In summary, according to the inspired by legal regulations such as the "prevention and treatment of occupational diseases of the people's republic of China" and the "technical requirements for light health and light safety application of blue light protective film", some oral medical practitioners choose to wear conventional blue light goggles, light curing lamp goggles and the like, so that the oral medical protective film has a certain protective effect and does not influence clinical observation. However, the conventional blue light goggles have a narrow blue light prevention range, more isolate <445nm electromagnetic waves, and a low isolation rate, generally isolate 20-80% of blue light electromagnetic waves, so the clinical protection effect is not good enough, and the oral medical staff does not recognize the blue light protection effect. The aim of clinical use of the light-curing lamp goggles determines that the manufacturing process is thick, the optical light-transmitting parameters are uncertain, the natural light transmittance is low, and the observation definition is low, so that the light-curing lamp goggles are only used in the light-curing operation, and few dentists are used for clinical treatment observation needing high precision.

Meanwhile, in the eye occupational disease protection of oral medical personnel, goggles are worn according to the regulation of the Chinese health industry standard Hospital isolation technical Specification for protecting dental spray. The best spray protection is the totally-enclosed eye-shield type goggles, but as tears are heated and transpired, lenses are condensed and fogged when meeting cold air, and the sight is seriously affected, so oral medical personnel generally select open type goggles.

When the open goggles are worn, in the clinical diagnosis and treatment process, a lot of droplets including blood, dental plaque, dental tissues, dental calculus, polishing materials, old repair materials and the like can be ejected at a high speed and cling to the outer layer of the medical mask from bottom to top, and the droplets enter eyes along the lower edge of the open goggles in an ejection mode, so that occupational exposure of the eyes is caused.

There is many medical care to choose to use double faced adhesive tape to bond goggles and gauze mask, nevertheless because the outer inviscid of gauze mask, the contact gap that gauze mask and open goggles picture frame were followed down simultaneously is not of uniform size, has facial muscle and respiratory gas's motion again, so, the double faced adhesive tape loses effect very fast, leads to the reflection of droplet multiple times and gets into the eye, leads to the occupation of eyes to expose.

In summary, in the field of occupational disease protection of eyes, a pair of protective glasses with glare interference, blue light injury prevention and eyesight sensitivity enhancement is needed for oral medical personnel at present, and the pair of protective glasses also has the functions of isolating dental spray and interfering light. The present invention has been made.
