The name
Born from light
Helio comes from Helios, the Sun. In 1868, while studying sunlight, scientists discovered a new element and named it helium. It was not found on Earth until 1895.

Size guide
Will they fit you?
Measure your face from temple to temple with a tape measure and compare it with each model’s total width, shown on its page.
- Narrow face (under 13.5 cm)135–140 mm
- Medium face (13.5–14.5 cm)140–145 mm
- Wide face (over 14.5 cm)145 mm or more
Measurements may vary by 1 to 3 mm depending on the model.
What is the difference between Aria and Duetto?
Aria are rimless sunglasses: the lens floats free, with nothing around it. There are two styles: Facetta, with a cut edge, and Chiara, with a smooth edge. Duetto are prescription-ready frames with magnetic sun clip-ons: you wear them as eyeglasses and, with the clip-on attached, as sunglasses. There are two styles: Filo, in metal, and Piuma, in TR90.
Do they protect from the sun?
Yes. All Aria lenses and all Duetto clip-ons have UV400 protection, which blocks UVA and UVB rays. Duetto clip-ons are also polarized.
Can I order them with my prescription?
Duetto, yes: choose With prescription and enter your prescription values. Each model shows the prescription range it is made in. Aria are non-prescription sunglasses.
Are they for men or women?
For anyone. Check the size guide to choose the width that best suits your face.
How long does my order take?
We prepare your order in 1 to 3 business days; if it has a prescription, we add a few days to make your lenses. You will see the estimated delivery time at checkout, and we email you the tracking number. If you order several models, they may arrive in separate packages.
Can I exchange or return them?
If they arrive damaged or are not what you ordered, write to us within 30 days with photos or a video and we will send you a new pair or refund you, with nothing to send back. We do not accept returns for a change of mind, and prescription glasses are made to your prescription; check the measurements before buying. See full policy.
How do I care for them?
Clean them with a microfiber cloth and a little warm water; avoid paper and alcohol-based products. Keep them in their case to protect the lenses, especially Facetta’s cut edge and Duetto’s clip-ons.
