Virtual live facilitator-led courses give you comprehensive training right from your own computer. Virtual Live Classroom (VLC) training provides hands-on learning, interactivity and participant engagement, all with the flexibility of learning from wherever you choose. Practical components are demonstrated whereafter the student completes the training requirements by gaining the necessary practical experience at a face-to-face practical training day that occurs on site in Cape Town, Johannesburg, Durban, George, Port Elizabeth, Nelspruit, Windhoek and Harare.

Ways to prevent computer vision syndrome:
Make screen viewing easier by regularly taking breaks. Use the 20-20-20 rule which means take a 20-second break every 20 minutes and focus the eyes on something about 20 feet away.
Simple eye care will help too. Have regular eye examinations. Describe the type of work done with the optician, which should include how much screen time is involved in the type of work being done.
Check eye prescriptions for glasses every 2 years. Tinted glasses, block wavelengths from fluorescent lights that can cause dizziness and headaches. These glasses, called blue blockers, may help with screening the wavelengths that computers emit.

Sometimes simple solutions are the best. Adjusting the screen’s contrast, brightness, and resolution. Don’t be tempted to increase it to the maximum resolution lower resolution and a larger font may be easier on the eyes and allow more effectively work.
Take control of the lighting. Don’t have the lights too bright and avoid glare. Get filters for computer screens that reduce glare, as well as glasses.
If the office or workspace has sunlight coming in, ensure correct positioning. Aim to have any sunlight behind the worker, instead of in front, ensure sunlight does not cause reflections on the screen.
Seating position is important. Sit upright and slightly downward at the centre of the computer screen.
Source the correct chair. It needs to support the back.
The placement of reference or ancillary materials can affect vision throughout the day. Additional equipment and materials like stationary, files, and notepaper, should be at the same distance from the computer screen. The eyes won’t have to change focus to look at these things.
If eye strain symptoms include dry eyes, dry eye treatments may help. Eye drops, or artificial tears, can help reduce discomfort during long days in front of the computer. The optometrist / OMP will recommend the best treatment option and determine whether dry eyes is due to digital eye strain or if there is another cause.
Improve the air quality of the office. Some changes that may help prevent dry eyes include using a humidifier, adjusting the thermostat to reduce blowing air and avoiding smoke. Stop smoking. Change the seating position to a different area in the office may help reduce the amount of dry moving air over the eyes and face.
Blink often to refresh the eyes. Many people blink less than usual when working at a computer, which can contribute to dry eyes. Blinking produces tears that moisten and refresh the eyes. All workers require instruction in the proper use and location of emergency showers or eyewash stations before any emergencies occur.
The procedures for reporting, correcting, and replacing defective PPE and for engineering noise control measures.
The training must be conducted prior to the placement of the relevant employee.
Refresher training shall be conducted annually or at intervals that may be recommended by the health and safety committee and the health and safety representative.
The training must be provided by a person who is competent to do so and who has adequate personal practical experience and theoretical knowledge of all aspects of the work carried out by the employee.
An employer or self-employed person shall ensure as far as is reasonably practicable that his or her mandatories or persons other than employees who may be affected by exposure at the workplace are given adequate information, instruction, and training.
An employer shall keep a record of any training that is given to an employee in terms of this regulation.
