Glare: The term 'glare' is sometimes used to refer to any visual aberration resulting from refractive surgery. In the author's opinion, this usage is archaic, and reflects a lack of understanding of the perceptual phenomena that afflict those with complications. Here, the term is restricted to situations in which light seems to overflow, or 'seep outside,' its normal boundaries around light sources, or sources of reflected light, such as shiny objects.

Directions:

• 1. Use the slider to change the amount of glare.

Limitations:

• 1. Many individuals who see glare, particularly those with larger pupils, will see more than one aberration, for example, glare combined with ghosting or blurry vision.
