We have never seen eye to eye on this matter. (我们对此事的意见从来就没有一致过) (正)
We have never seen eyeball to eyeball on this matter. (误)
解说：see eye to eye (with someone) 意为“(与某人) 看法完全一致”;eyeball to eyeball 意为“面对面 (face to face)。(尤指) 两名选手、两支球队、两支敌对军队等即将开打、厮杀而怒目相向、对峙”，如 In the playoffs we go eyeball to eyeball with the Tigers. (在季后赛中，我们将对抗老虎队);We are eyeball to eyeball with the enemy. (我们正与敌军对峙中)。英文并无 see eyeball to eyeball 这样的惯用语。
