- This concept will also be applied to anisometropes as they represent a unique example of ocular development, where the two eyes of an individual, with an identical genetic background and seemingly subject to identical environmental influences, can grow asymmetrically to produce significantly different refractive errors. This correction and manipulation strategy has the potential to be applied to the more hyperopic eye to encourage eye growth and reduction of hyperopia with associated benefits of improved binocular vision and stereopsis.
