Introduction to Occupational Health, Hygiene, and Safety
What is Occupational Health?
Occupational health is a specialized field of healthcare dedicated to the physical, mental, and social well-being of workers in all types of occupations. Its goal is to promote and maintain the highest degree of health and safety among employees in the workplace. This includes prevention of occupational diseases and injuries, promotion of health and productivity, and adaptation of work to individuals and vice versa.
For optometrists, occupational health plays a critical role in identifying visual demands in workplaces, assessing hazards that may affect the eyes, and implementing interventions such as corrective lenses or protective eyewear.
Key Principles of Occupational Health
- Promotion of Health: Encouraging healthy practices among workers.
- Prevention: Preventing occupational diseases and injuries before they occur.
- Adaptation: Matching the job to the worker and vice versa.
- Legal Compliance: Ensuring all workplace practices adhere to health and safety legislation.
Importance of Occupational Hygiene
Occupational hygiene involves identifying, evaluating, and controlling environmental stressors that may cause discomfort, illness, or injury among workers. These include:
- Physical hazards (e.g., noise, radiation, temperature)
