The antonym for "opened eyes" is "closed eyes." When we close our eyes, our vision becomes dark and blurry. It is a sign of relaxation, meditation, or sleep. When we have opened eyes, we are alert and aware of our surroundings. In some cultures, opening one's eyes symbolizes knowledge, wisdom, or enlightenment. However, closing them stands for ignorance, naivety, or dullness. Additionally, closing our eyes helps us focus on the other senses, such as listening or feeling. It also gives our eyes a break from the constant stimulation of light and colors. Therefore, both having opened and closed eyes have their advantages and purpose.
