Jos, You are right, optical parameters of a single eye play a role too. But because the image we "see" is a result of the brain combining the image from both eyes (if the binocular vision is working alright), - both play a role. The distance makes a difference, but when we are finding a lens

This news popped up on a few science websites yesterday (I suspect due to Rutgers' PR department's efforts), - and I just saw it on CBS morning news review this morning. https://phys.org/news/2018-03-distortive-effects-short-distance-nasal.html While what they discussed is fine, they
