Flirting can be a tricky subject, especially if you feel nervous around the person you like. Flirting using eye contact is good as it doesn't require you to think of witty phrases or even know too much about the person. Eye contact is one of the most powerful ways people use to convey attraction. However, it is also subtle enough not to pose any risk if you still do not know if the person you like is interested in you.
Steps
Method 1 of 3: Holding His Gaze

Step 1. Choose the ideal moment
Holding the gaze of your crush can be a great way to flirt, but it should be done at a good time. There is no way to plan the exact moment, but look for it to be when you can have their full attention without too many distractions.
- Don't pick a time when that person is distracted or busy. They won't be able to pay attention to you if they are. For example, don't try to hold his gaze while he's driving, reading, or working.
- A good time can be when you meet her and shake her hands, when you hand her something, or when you open the door to greet her.

Step 2. Catch their eyes
If you've already picked a good time, this shouldn't be difficult. They will likely make eye contact naturally when you show up or see her at the door. If it's a more difficult context, keep your eyes on that person until they realize you're looking at them.
If you are at a party or social event, position yourself so that you can see the eyes of the person you like. Keep your gaze on her as much as possible. Sooner or later, she will look up and probably notice that you are looking at her

Step 3. Maintain a welcoming facial expression
Let your expression be smooth. This can mean smiling slightly or even licking your lips a bit. If you freeze or look very serious, it may appear that you are staring instead of flirting.

Step 4. Maintain eye contact
Normal eye contact lasts about three seconds. However, if you can hold her gaze for a couple more, she'll have a strong clue that you're flirting with her. You can even hold their gaze longer if you prefer, as long as that person isn't looking away.
If you're feeling nervous, it's probably tempting to look away. However, try to maintain eye contact to help build tension. Doing so will make you feel confident and available, which are both attractive and powerful qualities
Method 2 of 3: Coy Eye Contact

Step 1. Catch their eyes
This can happen in a natural context, such as when they have to talk or are in a hallway. However, if you are in a busy social setting, keep your eyes on that person until they look at you and meet your gaze.
There is a difference between looking at someone normally and staring. Make sure your gaze shows curiosity and is welcoming. You don't want to seem impatient or upset

Step 2. Look down
Once your crush makes eye contact with you and you've held it for a couple of seconds, look away as if you're feeling shy (as you probably feel right now anyway). However, just lower your gaze for a moment. You don't want that person to put their attention on something else.
- You can look away from your lap or the floor to appear shy.
- If you're feeling bold, you can look down at another trait of the person that you like, such as their lips, chest, or groin. This can be very suggestive and can put someone off, but it's good if you want to be extremely obvious about your intentions.

Step 3. Look up slowly
Once you've lowered your gaze a bit, lift it up to meet his again. This person is likely to have an inquisitive expression on their face since you will have given them the clear signal that you are flirting with them.
- At this point, you will be able to maintain eye contact or look away again.
- If you are deep in conversation, keep talking. Feel free to keep eye contact and look down again when you want to appear flirtatious.
Method 3 of 3: Placing Facial Expressions and Gestures While Flirting

Step 1. Make eye contact with that person
You can perform this technique in any context. It is good if they work together or are already friends. If you are with multiple people, you may need to say or do something to get their attention to make eye contact.
Don't do anything fancy to get their attention. Just say "Excuse me, could you tell me the time?" A "hello" is enough

Step 2. Smile
It may be obvious. However, if you like someone, you are likely to feel nervous to the point of forgetting to smile. As soon as that person makes eye contact with you, put on a big, friendly smile.
People can unconsciously know if a smile is real or fake. To make sure your smile looks warm and genuine, show your teeth and make sure to squint, creating crow's feet on your face

Step 3. Add more energy
This may be a bit confusing as it is more subtle. To add energy to the interaction, simply let the positive and nervous feelings you feel around that person energize the way you look at them. Don't try to hide it. Some ways you can add energy are as follows:
- Take a deep breath and exhale through your mouth.
- Straighten your posture.

Step 4. Make another gesture or expression to convey that you are flirting
You can try waving, touching your face, winking, or running your hand through your hair. You can smile, avert your gaze a bit, and lick your lips if you're feeling a bit sassy. Choose a light facial gesture that works for you.
- Winking can be flirty, but it's sometimes seen as dated or even creepy depending on the context. Use your intuition to see if it will work with the person you like.
- You can also blink lightly and frequently when you're with her. This is something that people do unconsciously when they are with someone they are attracted to. This will be helpful in sending the subtle message that you like him.
