Love is not blind. People just don't understand why we chose the person we love or they have the wrong concept of love. Most of the time, this is said when you tend to like someone who's not that attractive. True love is not solely based on the appearance, though it can be a factor. A person can be blinded by love, but not the other way around.
Love is not blind. You can say that love is blind because maybe you love the person the most without knowing his or her true identity. That's you can say that love is blind.
