12.1.2.3-10 Glare and the Use of Eyeglasses

If users wear eyeglasses, bright light sources behind the user should be avoided.

Additional Information: For users wearing eyeglasses, bright lights can cause glare if the sources are located behind the user between 30 degrees above and 45 degrees below the line of sight, or behind the user within 20 degrees left or right of the line of sight, since eyeglasses can reflect glare into the eyes of the user from such positions.1472G
