expression
Proverb meaning that when in love, one loses the ability to see faults or make rational judgments. The literal translation 'love is blind' is the most common equivalent.
恋は盲目とはよく言ったもので、彼は彼女の欠点にまったく気づいていない。
They say love is blind, and he is completely unaware of her faults.
恋は盲目だから、周りの忠告も耳に入らない。
Because love is blind, even advice from others falls on deaf ears.
