Lower Order Aberrations (LOA) are the vision aberrations that can be corrected with glasses or contact lenses. You may think of LOA as the quantity of vision.

Higher Order Aberrations (HOA) are additional aberrations of the optics of the eye that affect the quality of vision. We have an article with more on Higher Order Aberrations that you may want to read.
