When a person is interested in something, their pupils will likely dilate somewhat. Look to the pupils as a sign that a woman is interested in a certain topic.

Conversely, raised eyebrows and constricted pupils together may mean surprise or shock. Lowered eyebrows or a single raised eyebrow may show frustration or skepticism.

Squinting may indicate suspicion or mistrust. If you are not in an improperly-lit area, which may also cause squinting, ask the woman directly if something is bothering her. Wide open eyes can indicate happiness or excitement. Take note of what makes this women open her eyes wide to find out more about her interests and passions.

For example, do not assume a woman’s eyes say “Yes,” when she is plainly stating “No” to your offers or propositions. Respect her words over the perceived value you want to see reflected in her expression.

Try to avoid intense stares. Make polite eye contact when someone speaks, but do not stare a woman down after she has stopped talking or if something else is calling your attention.

Listen to what she’s saying to give you an idea of what she is feeling. For example, when she says, “I really like learning about this subject,” take a look at her eyes and remember that expression as one that indicates joy.

Understand that a woman making frequent eye contact or avoiding eye contact may not be a sign of her romantic interests. If you want to know about a woman’s romantic feelings, you will get the most direct answer from politely inquiring directly.

Looking directly at someone’s mouth is also often thought to be part of a flirty gaze.

People often blink at different speeds. Compare the blinking around the person a woman desires to the amount she blinks when that individual is not around.

If you believe a woman is indicating romantic interest with her eyes, try letting her know by saying, “I get the sense that you like this person. Is that the case?” Do not assume that the eyes say something different than what she indicates verbally. Accept a woman’s answer when you ask for clarification, even if you aren’t certain her expressions correspond with what she’s saying.
