They say the eyes are the windows to the soul.
Allah tells the believing men and women to lower their gazes.
Tell the believing men to reduce [some] of their vision and guard their private parts. That is purer for them. Indeed, Allah is Acquainted with what they do.
Quran, Chapter 24, Verse 30
Eye contact communicates interest, feelings, and connection.
Between you and your wife, it will communicate all as well as love.
Many men talk to their wives without looking at them. They will stay locked on the television or their computer screen.
When she talks to you, turn towards her. Look at her.
Look her in the eyes. Let her know you’re interested and you care.
