Study Notes

Environmental Vision & Occupational Health

The presentation explores the relationship between the environment, workplace hazards, visual performance, and ocular health.
It emphasizes the importance of eye safety programs and the impact of environmental changes on ocular health.

US Eye Injury Registry

The US Eye Injury Registry tracks the types and causes of eye injuries nationwide.
This data is crucial for improving occupational eye safety programs.
The pie chart shows the distribution of eye injury types: Blunt Trauma, Penetrating Injury, Chemical Exposure, Thermal Burn, and Other.

Occupational Eye Safety Programs

These programs are designed to proactively protect workers' visual health and prevent workplace eye injuries.
Risk assessment is a crucial first step: it determines potential ocular hazards and job-specific visual demands.
Based on the assessment, appropriate hazard controls are implemented: engineering controls, administrative policies, and PPE.
Education and training are provided to workers on eye safety best practices, hazard awareness, and the correct use of PPE.

Visual Demands and Ocular Hazards at Home

Household chores and home maintenance tasks can expose the eyes to dust, chemicals, bright light, debris, and sharp objects, causing eye strain and irritation.
Recreational activities, such as gardening, crafting, and reading, can also lead to eye strain, fatigue, and damage from UV radiation.
Improper lighting conditions (glare and shadows) in the home can lead to visual discomfort.

Visual Demands and Ocular Hazards at Work

Prolonged computer use can lead to eye strain, dry eyes, and Computer Vision Syndrome.
Working with machinery, tools, or chemicals can cause eye injuries from debris, impacts, and splashes.
Improper lighting, glare, and reflections can cause eye fatigue and headaches in a workspace.

Visual Demands and Ocular Hazards in Recreation

Outdoor activities, like hiking, camping, and water sports, can expose the eyes to bright sunlight, UV exposure, airborne debris, and fast-moving objects, causing eye injuries or strain.
Indoor hobbies, such as crafting, model building and gaming, can cause eye strain due to the prolonged close-up work, poor lighting and glare from screens.

Materials Designed for Safety
