Medical protective eyeshade for preventing harmful light and infection after eye operation

Abstract

The invention discloses a medical protective eyeshade for preventing harmful light and infection after an eye operation, which comprises an eyeshade frame body, lenses arranged in the eyeshade frame body, an elastic isolation gasket which is arranged on the eyeshade frame body and is in close contact with the skin around the eyes and the nose of a wearer, and elastic bandages arranged on the two sides of the eyeshade frame body, wherein the eyeshade frame body is provided with at least one vent hole assembly for ventilating eyes, each lens comprises a resin lens substrate, and the following components in parts by weight are also added into each resin lens substrate: 80-200 parts of coloring agent; 4-10 parts of a dyeing assistant; 5-6 parts of an ultraviolet light absorber; and 10-20 partsof a short-wave visible light absorbent. According to the invention, the protection concept of 'absorption' or 'blocking' of the traditional protection lens is broken through, and the protection concept of 'absorption-blocking' is adopted, so that the problem that harmful light with different wavelengths cannot be thoroughly protected is solved, and the object color of an object is not changed when a wearer sees the environment.

Description

technical field [0001] The invention belongs to the technical field of surgical medical instruments, and in particular relates to a medical protective goggle for preventing harmful light and infection after eye surgery. Background technique [0002] With the continuous advancement of science and technology, electronic products are inseparable from people's lives. Computers, mobile phones and other products have brought great convenience to people's work and life, and have also changed people's eye habits. The most important thing is the damage to eye health, which leads to more and more people suffering from eye diseases. Some eye diseases need to be solved through surgical treatment. At present, after ophthalmic surgery in hospitals, patients often need to wear goggles for a period of time. Finally, it is very important to protect the affected part of the eye, which is related to whether the patient can recover quickly. Sunlight, lights, blue light emitted by electronic sc...

Problems solved by technology

[0008] The above-mentioned patented technology prevents harmful ultraviolet rays, blue light and other harmful light that are harmful to the eyes to a certain extent, and improves the protective effect of the eyes, but there are still some problems. For example, the above-mentioned technologies all use coatings to block harmful light. , filter, but at the same time it also blocks the entry of beneficial light to a certain extent, and when patients or users wear it, the coating will inevitably have a certain impact on the line of sight and light. The visible light transmittance is low, resulting in darker vision , Long-term wearing will also affect vision, and the color of colored lenses will change when looking at objects, affecting the normal vision of the wearer

The most critical point is that most of the current traditional harmful light protection lenses have the protection principle of "absorption" or "blocking". If the wavelength range of harmful light is limited by adding an absorber, the protective effect is poor; if it is only blocked, both the beneficial light and the harmful light are blocked by the coating method, which affects the visual effect and eye rehabilitation effect
