- Contact lenses: Used for cosmetic or vision correction purposes, available in colored, contrast-enhancing, or multifocal types.
- Ultraviolet protection glasses: Protect eyes from harmful ultraviolet radiation, blocking UVA and UVB rays.
- Protective glasses: Used in workplaces requiring eye safety such as construction sites, industries, or extreme sports, protecting against impact, dust, cuts, or hazardous substances.
2. Overview of Occupational Environment Monitoring Services
a. What is occupational environment monitoring at an eyeglass manufacturing factory?
Occupational environment monitoring (or workplace environmental measurement) at an eyeglass manufacturing factory involves collecting, evaluating, and analyzing workplace environmental factors to implement timely measures, minimize health risks to workers, and prevent occupational diseases. This monitoring is mandatory for eyeglass manufacturing factories.
It plays a critical role in protecting and improving worker health because employees are the main resources of enterprises and directly generate profits. Workers frequently exposed to harmful factors beyond permissible limits are at risk of health problems and occupational diseases.
