Buying glasses online is tricky: the frames look great on the model, but will they suit your face shape? Virtual try-on shows you on your own photo, before you order or visit an optician.
Upload a portrait facing the camera — a regular selfie works — and add the glasses: a photo from an online store, a shot of the frames on a table, or a link to the product page. Under “What you're trying on”, choose “Accessory or shoes”, and add wishes if you like: “sunglasses pushed up on the head”, “clear lenses”.
Google's Nano Banana 2 puts the glasses on, matching the shape, color and material from the product photo, while your face, hair and background stay yours. Upload your photo once: next time the try-on uses it automatically, so you only swap frames. You're only charged for successful results.
