Is there a clear standard for medical goggles to refer to for testing?
The answer is yes! This standard is a local standard formulated during the SARS period. DB11/188-2003 "Technical Requirements for Medical Protective Glasses" implemented by Beijing Quality Inspection Bureau in 2003. DB11/188-2003 stipulates 13 test items for medical protective glasses, namely vertex deviation, prism deviation, lens ring size, surface quality and internal flaws, appearance quality, visible light transmittance, impact resistance, assembly Quality, plastic requirements, high temperature resistance, corrosion resistance, and disinfectant resistance. Although DB11/188-2003 is the counterpart, but considering it is a local standard, and the implementation time, the testing items are not perfect, etc., it can only be used for reference.
One of the most basic requirements for medical goggles testing is harmlessness. In particular, the harmful substances precipitated from the goggles material have toxicological properties such as sensitization, carcinogenicity, and mutagenicity to the eyes. The toxicological performance of medical goggles can be analyzed with reference to GBZ/T 240.5-2011 "Chemical Toxicology Evaluation Procedures and Test Methods Part 5: Acute Eye Irritation/Corrosion Test". You can refer to the test.
In summary, the standards that can be referred to for the detection of medical goggles are GB 14866, YY/T 0128, DB11/188, and GBZ/T 240.5. In addition, we should pay attention to breathability, leakage performance, antivirus performance, etc. After long-term use of medical goggles, the eyes will have hypoxic reaction and cause eye fatigue, so proper air permeability must not be small. While packaging certain air permeability, it must also have certain leakage resistance. Of course, the need for antivirus performance is self-evident.
