Talk:Visual angle

Untitled
Its quite unfortunate to use "n" for a distance in optics. This letter is almost always used for the index of refraction.

Intro/Definition
Instead of jumping right into the technical aspects a basic introduction or definition that explains briefly what the Visual angle is should be included. Preferably in simple or laymans terms. — Preceding unsigned comment added by 72.11.91.140 (talk) 03:01, 3 April 2014 (UTC)
