The following NYSOA guidelines can help prevent or reduce eye and vision problems associated with computer vision syndrome:
• Check the height and arrangement of the computer. According to optometrists, a computer screen should be 15 to 20 degrees below eye level (about 4 or 5 inches) as measured from the center of the screen and held 20 to 28 inches away from the eyes.
• Check for glare on the computer screen. If possible, windows or other light sources should not be directly visible when sitting in front of the monitor. If this happens, turn the desk or computer to prevent glare on the screen.
• Reduce the amount of lighting in the room to match the computer screen. A lower-wattage light can be substituted for a bright overhead light or a dimmer switch may be installed to give flexible control of room lighting.
• Keep blinking. To minimize the chances of developing dry eye when using a computer or digital device, make an effort to blink frequently. Blinking keeps the front surface of the eye moist.
Most importantly, as part of the yearly, back-to-school checklist, students should see a doctor of optometry for a comprehensive eye examination to ensure their eyes are healthy and functioning properly.
