Re: Myopia, binocular vision and Class 1
Just to clarify a previous post, esophoria is a hidden or latent extra-ocular muscle imbalance. In other words it is a condition for a tendency for the eyes to either move inwards (esophoria) or outwards (exophoria). The presence of an eso- or exo-phoria is not noticeable when simply looking at someone, it can only be detected under certain test conditions. However, a tropia (esotropia or exotropia) is a visible "squint" and is obviously noticeable to anyone who would see an eye squinting either inwards or outwards.
