41. IMAGE DISPARITY
This condition may exist when there is a difference in brightness between the two image-intensifier assemblies within the same binocular.

42. OUTPUT BRIGHTNESS VARIATION
This condition is evidenced by areas of varying brightness in or across the image area. The lower contrasts do not exhibit distinct lines of demarcation nor do they degrade image quality. Do not confuse output brightness with shading.
