How to Use Eye Shape Detector to Test Your Eye Shape

Eye Shape Detector with AI (eyeshapedetector.app) tests your eye shape in three steps: upload a clear, well-lit photo of your eyes, click Analyze, and read the detailed analysis result. It works on any device with a browser, accepts PNG and JPG files up to 10MB, and needs no account or download. The catch is photo quality — the tool's own tips ask for natural light, open and relaxed eyes, a direct look at the camera, and no heavy makeup or glasses, because those are the conditions under which the AI can actually see your eyelid crease, iris position, and outer-corner angle.

What you need before you start

• A photo where both eyes are visible and in focus
• PNG or JPG format, up to 10MB
• Lighting that shows your eye area clearly — natural light is what the site recommends
• No heavy eye makeup and no glasses, since both hide the features the detector reads

You can either upload an existing file or use the camera option on the page. If you shoot a new photo, face a window or another even light source rather than a lamp directly overhead, which casts shadows into the crease.

Step-by-step: running the test

1. Upload your photo

On the upload area, either click to browse your files or drag and drop the image. The page also offers a camera button if you'd rather take the photo on the spot. Accepted formats are PNG and JPG, maximum 10MB.

2. Click Analyze

Press the analyze button. The tool processes the photo and identifies your eye shape.

3. Read the analysis results

The result page gives a detailed eye shape analysis. The site groups eyes into common shapes including:

Match your result against these descriptions to sanity-check it. If the analysis says "almond" but your outer corners clearly sit lower than your inner corners in the same photo, the photo is the more likely problem — retake it before trusting the label.

How to get a more reliable result

The site's own guidance for best results:

• Use good lighting, natural light preferred
• Keep your eyes open and relaxed — don't squint or widen them deliberately
• Look directly at the camera
• Avoid heavy makeup or glasses

A few practical additions to those:

• Take the photo at eye level. Shooting from below or above changes the apparent angle of your outer corner, which is exactly what separates upturned from downturned.
• Don't smile hard. A strong smile squints the lower lid and can make round eyes read as narrower.
• Compare two photos. Run the test on a second photo taken in different light. If both give the same shape, you can be reasonably confident; if they disagree, the disagreement usually points to lighting or angle rather than your actual anatomy.

Common snags

• Upload rejected. Check the file is PNG or JPG and under 10MB. Screenshots saved as other formats, or photos straight from some phone cameras in HEIC, won't pass.
• Both eyes not detected. Crop tighter around your eyes, or retake the photo with your whole eye area in frame and your face straight-on.
• Result feels wrong. Almost always a photo issue: glasses, shadow across the crease, a tilted head, or a downward gaze. Retake under natural light looking straight at the lens.
• Heavy eyeliner or shadow. It fills in or hides the crease, which is one of the main signals the detector uses. Remove it for the test photo.

Privacy and responsible use

The site includes a section on privacy, safety, and responsible use, so treat your photo as personal data: upload only what you're comfortable sharing, and avoid using photos of other people without their consent. An eye shape result is a descriptive label, not a medical assessment — if you have a concern about your eyes or vision, that's a question for an eye care professional, not a shape detector.
