Binocular Visual Acuity in Intermittent Exotropia: Role of Accommodative Convergence

What is it about?

Minus (short sighted) lenses are sometimes used to treat intermittent divergent strabismus (squint). We propose that the lenses may not do this by "making the eyes focus more", but might work by correcting any over-focus induced by the need to converge more to overcome a primary divergent eye position

Why is it important?

This is an alternative explanation for the mechanism of a commonly used treatment for intermittent divergent squint
