In our previous write-up, we discussed the meaning of computer vision syndrome (CVS) and the symptoms that accompany the condition. In this concluding part, we look at practical ways to manage computer vision syndrome.
SIMPLE WAYS TO MANAGE COMPUTER VISION SYNDROME
- POSITION OF COMPUTER/SMART DEVICE SCREEN: Place monitor directly in front of you, not off to one side. It should be about 20 – 28 inches away from you, placed not too high or blow preferably 15 – 20 degrees below eye level
- CONTRAST: Adjust contrast between the background and characters on the screen and even brightness
- REFERENCE MATERIALS: Place materials above the keyboard and below the monitor/screen so you do not move your head to look from document to screen. Get a document holder that is well lit beside the monitor
- LIGHTING: Use fewer bulbs, fluorescent bulbs or bulbs of lower wattage in addition to window blinds or drapes to reduce glare from overhead lighting or windows
- ANTIGLARE: Use antiglare screens for monitors that are compatible or special lenses from eye doctor. Sunglasses not ideal!
- SEATING POSITION: Good seating position with back straight and shoulders back. Right chair height and adjusted so that your arms are parallel to the floor when you type. Feet should also be flat on the floor or on footstool.
- REST BREAKS: Rest eyes for 15 minutes after 2hours of continuous computer use. Alternatively, for every 20minutes of computer viewing, focus on an object 20feet away for 20seconds (the 20-20-20 rule)
- BLINKING: Blink regularly to avoid dry eyes
- Regular visits with an eye doctor for your eye and visual needs: Even if you don’t need glasses or contact lenses for daily activities, you may need them for computer or device use. An eye checkup to get the right prescription can help prevent pain in the neck, shoulders or back that results from contorting your body to see the screen.
In conclusion, aside from the physical discomfort you may experience from the symptoms, computer vision syndrome (CVS) can have a lasting effect on your vision even after stopping work at a computer. The time to act is now!!!!!!!!
