Occupational Safety Training for Eyeglass Manufacturing

1. Overview of Eyeglasses

a. What are Eyeglasses?

• Eyeglasses are a type of device or material that includes a frame surrounding the eyes and one or two lenses inserted to protect and enhance the wearer’s vision.
• Eyeglasses are used to correct vision problems such as myopia, hyperopia, presbyopia, lazy eye, dry eyes, and glare, and they also protect the eyes from external factors such as strong light, dust, insects, and impact objects. Additionally, eyeglasses are used for decoration and to express the wearer’s style.
• The eyeglass manufacturing industry in Vietnam is currently developing, with many businesses operating in this sector. According to statistics from the General Statistics Office of Vietnam, the production of eyeglasses in 2020 was over 11 million units, an increase of 3.3% compared to the previous year. However, this production only meets approximately 50% of domestic demand, with the remainder imported.

b. Eyeglass Manufacturing Machinery

The machinery used in eyeglass manufacturing includes:

• Glass cutting machines: Use cutting tools with computer-controlled cuts to create glass pieces of the required size and shape.
• Glass grinding machines: Use grinding stones to sand and shape the glass. Machines can be programmed to create different shapes for eyeglass lenses.
• Anti-glare coating machines: Use electrochemical processes to apply an anti-glare film on the lenses. Computers adjust the coating process for precision and contrast.
• Glass milling machines: Use milling tools to remove excess glass and create precise edges.
• Lens measuring machines: Use laser technology to measure lens dimensions and ensure production accuracy.
• Engraving machines: Use lasers to engrave patterns, logos, or letters on the lens surface.
• Glass tempering machines: Use high pressure and temperature to temper the glass, increasing durability and strength.

c. Prominent Eyeglass Manufacturers in Vietnam

Currently, several companies manufacture eyeglasses in Vietnam, including:

• Vietnam Optical Co., Ltd – Việt Optical: One of the leading companies producing and trading eyeglasses in Vietnam, established in 1960, headquartered in Ho Chi Minh City.

2. Overview of Occupational Safety Training for Eyeglass Manufacturing

This article focuses on Group 3 because Group 3 directly participates in production and faces the highest occupational safety risks. For other groups, see here.

a. What is Group 3 Occupational Safety Training?

• Group 3 occupational safety training consists of sessions that raise awareness and teach workers how to prevent occupational accidents.
• The training helps workers recognize hazards and avoid risks to minimize workplace accidents.

b. Training Duration

Initial safety training

• Total training duration is at least 24 hours, including assessment time.
• 8 hours of theoretical study on safety policies and labor hygiene laws
• 8 hours of theoretical study on basic occupational safety and hygiene knowledge
• 4 hours of theoretical study on specialized training content
• 2 hours of practical training on specialized content
• 2 hours of theoretical assessment at the end of the course

The safety training center schedules multiple sessions depending on worker availability. Typically, there are 6 sessions over 3 days, provided the manufacturing company allows continuous training.

Periodic safety training

• Before the occupational safety card expires, workers who want reissuance must undergo periodic occupational safety training for at least 50% of the initial training duration.

Explanation: The total periodic occupational safety training duration is at least 12 hours, including assessment time. After completing the course and passing the assessment, workers are reissued and have their occupational safety cards extended.

c. Training Content

d. Occupational Safety Card

After completing occupational safety training and passing the assessment, workers will be issued a occupational safety card (commonly called Group 3 safety certificate).

The Group 3 safety card displays information such as full name, date of birth, specific job and working environment, training duration, official seal, and signature confirming completion.

According to regulations on card issuance specified in Clause 2 of Article 24, Decree 44/2016/ND-CP, there are two cases:

• If the employer and employee have a labor contract, the employer must sign, stamp, and certify the Group 3 occupational safety card after the worker completes the training and passes the assessment.
• If the worker is freelance or seasonal and does not have a labor contract, the training unit must sign, stamp, and certify the card after the worker completes the training and passes the assessment.

3. Identifying Hazards Affecting Workers in Eyeglass Manufacturing

Some hazards affecting workers during eyeglass manufacturing may include:

• Risk of eye injury may occur during the eyeglass production process, especially when cutting, grinding, and polishing lenses. To prevent this risk, workers should use protective glasses, enhance occupational safety training, and comply with safety procedures.
• The eyeglass production process may involve the use of chemicals and hazardous materials such as acids, solvents, and adhesives. Direct contact with these substances can cause skin burns or chemical burns. To ensure safety, workers need to use full protective equipment and follow safety procedures during work.
• Machinery and equipment used in eyeglass production can cause occupational accidents if not used properly or maintained regularly. To avoid accidents, workers should be trained in the use of machinery, maintenance, and periodic equipment servicing.
• The eyeglass manufacturing process may generate dust and toxic fumes. Inhaling this dust and fumes over long periods can be harmful to workers’ health. To ensure safety, it is necessary to use full protective equipment, especially dust and chemical-resistant masks.

4. Common Occupational Accidents in Eyeglass Manufacturing

Some common occupational accidents during eyeglass manufacturing include:

• Cuts, tears, or punctures to hands from cutting blades, knives, sharp materials, or rough raw materials.
• Eye and skin damage due to strong light from glass processing machines, lighting, or fine dust during polishing.
• Hearing loss due to loud noise from machinery.
• Chemical poisoning from exposure to chemicals such as solvents, dyes, cleaning agents, and opacifying agents.
• Slips and falls due to wet floors or moving in confined spaces.
• Injuries from heavy objects, collisions with machines, or equipment.
• Mental health issues, stress, and psychological pressure.

5. Safety Measures When Participating in Eyeglass Manufacturing

Safety measures when participating in eyeglass manufacturing include:

• When working in an eyeglass manufacturing factory, workers should use personal protective equipment such as safety glasses, gloves, masks, helmets, and anti-puncture shoes to ensure body safety.
• Eyeglass manufacturing machinery should be regularly inspected to ensure safety and product quality. Additionally, electrical lines, piping systems, and mechanical systems must be properly maintained and repaired.
• Employees working in the eyeglass factory need training on safety regulations and procedures, how to use personal protective equipment, and emergency measures in case of incidents.
• During eyeglass production, safe and compliant materials should be used to ensure product safety. Materials must also be stored properly and free from contamination.
• Eyeglass production often involves chemicals and high temperatures, so fire and explosion prevention measures should be implemented, including occupational hygiene, regular inspection of fire-fighting systems, and identifying hazardous areas.
• Factories must comply with labor safety, environmental protection, and product quality regulations.
• Regularly conduct occupational environment monitoring in the factory to collect and analyze harmful factors affecting workers, thereby reducing risks and preventing occupational diseases.
