			==Positive vs. Negative Cylinder==
			Eyecare professionals have individual preferences for writing out positive vs negative values for cyl. For discussion with other EM participants, it is usually recommended to convert positive cylinder values into their negative equivalent, as the negative cylinder values are potentially more intuitive from a reduction point of view.

			* For example, there are participants who get surprised [https://www.youtube.com/watch?v=AJQEdXwKiNA&t=1363s when they remove plus cylinder, and then find that the glasses they order are too strong].
